# Line 1  Line 1 
1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3      * SFZ format engine:
4        - added support for <global>, <master> and #define (patch by Alby M)
5        - Removed code duplication in SFZ file loading code.
6        - Added support for sfz extension opcode 'script' which may be used to
7          load real-time instrument script file (NKSP script language).
8        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
9        - Fixed unintended volume fade-in of voices under certain conditions.
10        - sfz parser: allow missing space between header and opcode
11    
12      * Gigasampler/GigaStudio format engine:
13        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
14          cutoff settings.
15        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
16          all if an up-pitch of more than 40 semi tones was requested (I don't
17          think there is any stock gig sound that requires this behavior to
18          resemble its original sound).
19        - Added support for controlling whether the individual EGADSR stages may
20          be aborted (as LinuxSampler extension to the original GigaStudio 4
21          format).
22    
23      * general changes:
24        - fixed printf type errors (mostly in debug messages)
25        - use unique_ptr instead of auto_ptr when building with C++11
26        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
27          allowing to sort data efficiently in real-time safe manner.
28        - RTList class: added methods for moving/inserting elements to arbitrary
29          position within a list.
30        - RTList class: added method fromPtr() for creating an Iterator object from
31          a raw element pointer.
32        - Attempt to partly fix resetting engine channels vs. resetting engine, an
33          overall cleanup of the Reset*(), ConnectAudioDevice(),
34          DisconnectAudioDevice() API methods would still be desirable though,
35          because the current situation is still inconsistent and error prone.
36        - Active voices are now internally grouped to "Note" objects, instead of
37          being directly assigned to a keyboard key. This allows more fine graded
38          processing of voices, which is i.e. required for certain instrument
39          script features.
40        - Fix: Release trigger voices were not spawned on sustain pedal up
41          (CC #64) events.
42        - Fix: Release trigger voices can now also distinguish correctly between
43          note-off and sustain pedal up events.
44        - All engines: Increased ramp speed of volume smoother and pan smoother
45          (while slow rate of crossfade smoother is preserved) to allow quick
46          volume and pan changes by instrument scripts for instance.
47        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
48          properly and thus were ignored for certain uses.
49        - Added new C++ API method
50          VirtualMidiDevice::SendChannelPressureToSampler().
51        - windows, 32-bit: fixed potential crashes by making sure the stack in
52          sub threads is 16-byte aligned
53        - fixed numerous compiler warnings
54        - Fixed invalid (note-on) event ID being assigned to new Note objects.
55        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
56          fixes potential undefined behavior.
57        - Fixed Note object leak when triggering notes on keys which did not
58          have a valid sample mapped (fixes bug #252).
59        - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
60    
61      * packaging changes:
62        - removed unnecessary dependency to libuuid
63          (originated by libgig's usage of it)
64        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
65          auto detect whether it (sh/c)ould output its messages in color.
66        - Debian: Fixed packaging error about invalid "Source-Version"
67          substitution variable.
68        - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
69    
70      * Real-time instrument scripts:
71        - Implemented scheduler for delayed MIDI events and for suspended scripts.
72        - Built-in script function "wait()": implemented support for function's
73          "duration-us" argument, thus scripts using this function are now
74          correctly resumed after the requested amount of microseconds.
75        - Built-in script function "play_note()": implemented support for
76          function's "duration-us" argument, thus notes triggered with this
77          argument are now correctly released after the requested amount of
78          microseconds.
79        - Fix: script events were not cleared when engine channel was reset,
80          potentially causing undefined behavior.
81        - Fixed crash which happened when trying to reference an undeclared
82          variable.
83        - Built-in script function "play_note()": Added support for passing
84          special value -1 for "duration-us" argument, which will cause the
85          triggered note to be released once the original note was released.
86        - Instrument script classes now exported with the liblinuxsampler C++ API.
87        - Added new API method ScriptVM::syntaxHighlighting() which provides
88          a convenient syntax highlighting backend for external instrument
89          script editor applications.
90        - Added new C++ API class "ScriptVMFactory".
91        - Extended parser issues to provide not only first line and first
92          column, but also last line and last column of issue (thus marking
93          the precise span of the issue within the source code).
94        - Reload script automatically after being modified by an instrument
95          editor.
96        - NKSP language grammar correction: allow empty event handler bodies
97          like "on note end on".
98        - Implemented built-in script function "change_vol()".
99        - Implemented built-in script function "change_tune()".
100        - Implemented built-in script function "change_pan()".
101        - Implemented built-in script function "change_cutoff()".
102        - Implemented built-in script function "change_reso()".
103        - Implemented built-in script function "event_status()".
104        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
105          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
106          "event_status()" function.
107        - NKSP language: Added support for bitwise operators ".or.", ".and."
108          and ".not.".
109        - NKSP language scanner: Fixed IDs matching to require at least one
110          character (i.e. when matching function names or variable names).
111        - NKSP language scanner: disabled unusued rules.
112        - Fixed behavior of play_note() and note_off() functions which must
113          be distinguished engine internally from "real" MIDI note on/off
114          events in order to avoid misbehaviors like hanging notes.
115        - Implemented built-in script variable "$KSP_TIMER".
116        - Implemented built-in script variable "$NKSP_REAL_TIMER".
117        - Implemented built-in script variable "$NKSP_PERF_TIMER".
118        - Implemented built-in script variable "$ENGINE_UPTIME".
119        - Implemented built-in script function "inc()".
120        - Implemented built-in script function "dec()".
121        - NKSP language fix: division expressions were evaluated too often.
122        - NKSP language fix: string concatenation operator was right
123          associative instead of left (to right).
124        - NKSP language correction: allow empty statements in entire language
125          (i.e. "if end if").
126        - Implemented built-in script function "stop_wait()".
127        - Implemented built-in script variable "$NI_CALLBACK_ID".
128        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
129        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
130        - Added support for read-only built-in variables (respectively
131          handled by the script parser).
132        - Added built-in script constant "$NI_CB_TYPE_INIT".
133        - Added built-in script constant "$NI_CB_TYPE_NOTE".
134        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
135        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".

138        - Implemented built-in script function "change_decay()".
139        - Implemented built-in script function "change_release()".
140        - Fixed all change_*() built-in script functions to apply their
141          synthesis parameter changes immediately in case the respective note
142          was triggered at the same time, instead of scheduling the parameter
143          change, especially because it would cause some parameter types's
144          changes either to be ramped (i.e. change_vol()) or other types even
145          to have not effect at all (i.e. change_attack()).
146        - Implemented built-in script function "sh_left()".
147        - Implemented built-in script function "sh_right()".
148        - Implemented built-in script function "min()".
149        - Implemented built-in script function "max()".
150        - NKSP Fix: "init" event handler was not always executed when a script
151          was loaded.
152        - NKSP built-in wait() script function: abort script execution if
153          a negative or zero wait time was passed as argument (since this is
154          a common indication of a bug either of the script or even of the
155          engine, which could lead to RT instability or even worse).
156        - ScriptVM: Implemented automatic suspension of RT safety
157          threatening scripts.
158        - Provide more user friendly error messages on syntax errors.
159        - Fixed NKSP parser warning "Not a statement" when assigning an
160          initializer list to an array variable.
161        - Implemented built-in script array variable "%ALL_EVENTS".
162        - Implemented built-in script function "in_range()".

165        - Implemented built-in script function "change_pitch_lfo_depth()".
166        - Implemented built-in script function "change_pitch_lfo_freq()".
167        - Implemented built-in script function "change_vol_time()".
168        - Implemented built-in script function "change_tune_time()".
169        - Implemented built-in script function "fade_in()".
170        - Implemented built-in script function "fade_out()".
171        - Fixed acceptance of wrong data type of parameters passed to built-in
172          script functions "change_vol()", "change_tune()", "change_pan()",
173          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
174          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
175          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
176        - Added built-in script function "get_event_par()" and implemented some
177          of its possible parameter selections.
178        - Added built-in script function "set_event_par()" and implemented some
179          of its possible parameter selections.
180        - Fixed a bunch of scheduler time related bugs.
181        - Fixed polyphonic variables not being reset to zero after usage.
182        - Built-in "ignore_event()" function: argument is now optional, like with
183          built-in function "ignore_controller()".
184        - Implemented built-in script function "change_velo()".
185        - Implemented built-in script function "change_note()".
186        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
187          intuitive behavior if used in combination with "change_vol_time()" or
188          "change_tune_time()" respectively: now tuning/volume changes are only
189          assigned (without delay) immediately to a new note if the respective
190          timing function has not been called before, otherwise the volume/tuning
191          changes are automatically faded (before, only the event's time stamp was
192          relevant).
193         - Implemented built-in script function "array_equal()".
194         - Implemented built-in script function "search()".
195         - Implemented built-in script function "sort()".
196         - NKSP Fix: Never suspend "init" event handlers.
197         - Implemented built-in script function "same_region()" (currently only
198           available for gig format engine).
199         - Added built-in script constant "$NKSP_LINEAR".
200         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
201         - Implemented built-in script function "change_vol_curve()".
202         - Implemented built-in script function "change_tune_curve()".
203         - built-in "play_note()" function now supports a sample playback start
204           offset with argument 3, where special value -1 means to use the regular
205           sample offset as defined by the instrument file.
206         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
207         - Built-in variable $EVENT_NOTE is now a read-only variable.
208         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
209         - built-in "play_note()" function now accepts -2 for its fourth argument
210           (note duration) which means the life time of the note shall be sticked
211           to the requested note number of argument 1.
212         - Fix: built-in "play_note()" function now returns 0 as result value if
213           -1 was passed for its fourth argument (note duration) and the respective
214           parent note is already gone.
215        - Implemented built-in script function "change_play_pos()".
216        - NKSP language: Added support for user declared const array variables.
217        - NKSP language: Raise parser warning if array variable is accessed with
218          an index that exceeds the array's size.
219        - NKSP language fix: Unknown characters were not handled correctly.
220        - NKSP language: Added support for "synchronized .. end synchronized"
221          code blocks.
222        - Implemented built-in script function "abort()" which allows to abort
223          another script handler by passing its callback ID.
224        - Fixed potential memory access bug and potential undefined behavior of
225          "init" event handlers.
226        - Print a time stamp along to each call of built-in function "message()".
227        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
228          to retrieve all code blocks filtered out by the preprocessor.
229        - Added built-in script function "fork()".
230        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
231        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
232        - Fixed potential crash when accessing dynamic built-in array variables.
233        - Added built-in script function "callback_status()".
234        - Added built-in constant $CALLBACK_STATUS_TERMINATED.
235        - Added built-in constant $CALLBACK_STATUS_QUEUE.
236        - Added built-in constant $CALLBACK_STATUS_RUNNING.
237        - Removed max. value limitation of built-in functions "change_attack()",
238          "change_decay()" and "change_release()" to i.e. allow passing 2000000
239          for doubling the respective time.
240        - NKSP script editor syntax highlighting API: Fixed app termination due
241          to a lexer start condition stack underrun.
242        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
243          USE_CODE_IF_NOT() preprocessor statements.
244        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
245          can be set to disable all subsequent built-in "message()" function calls
246          on preprocessor level.
247        - Implemented built-in script function "change_sustain()".
248        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
249          to avoid the editor app to crash on ill-formed text input.
250        - Added built-in script function "change_pan_time()".
251        - Added built-in script function "change_pan_curve()".
252    
253      * Instruments DB:
254        - Fixed memory access bug of general DB access code which lead to
255          undefined behavior.
256        - Cleanup of instruments DB file creation and opening code.
257        - The instrument DB path of linuxsampler's --create-instruments-db argument
258          is now optional, if it is missing, then a default location is used.
259        - Added support for scanning SFZ (.sfz) files.
260        - Added support for scanning Sound Font (.sf2) files.
261        - Fixed undefined DB transaction behavior.
262

265      * packaging changes:
266        - fixed building with newer MinGW-w64
267        - Mac OS X: support the new dir for Core Audio SDK
268        - Mac OS X: fixed building outside source directory
269        - made sure all source files for hostplugins are included when
270          doing "make dist"
271        - removed empty directories left from the cvs to svn migration
272        - fixed compilation with gcc 4.6.1
273        - another "make dist" fix, for the LV2 plugin
274        - made --enable-pthread-testcancel default on Mac OS X
275        - minor Makefile fix for building lscpparser when build and source
276          directories are separate
277        - Mac OS X: made it possible to specify plugin installation dir to
278          configure
279        - Mac OS X: Makefile fix for the install-strip target
280        - fixed compilation with gcc 4.7
281        - fixed configure script error with old autoconf versions
282        - lsatomic.h: use gcc provided atomic functions if building with
283          gcc 4.7 and C++11
284        - modernized configure script
285        - fixed linkage error when building with
286          LDFLAGS="-Wl,--no-undefined" (#190)
287        - fixed compilation with Clang 3.2

297        - support building with older jack versions
298        - support building with spaces in vst sdk path
299        - enabled automake 'subdir-objects' option and moved external
300          source references (vst, au, asio) from makefiles to cpp files,
301          in order to get rid of warnings from automake 1.14
302    
303      * general changes:
304        - Refactoring: moved the independent code from
305          the Gigasampler format engine to base classes
306        - command line option '--profile' is currently disabled, since the
307          respective profiling code is currently broken
308        - Introduced support for optional environment variable
309          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
310          where the sampler shall look for instrument editor plugins
311          (patch by Luis Garrido, slightly modified).
312        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
313        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
314        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
315          note (in this implementation of the sampler its simply hard routed to
316          the 1st effect send of the sampler channel, no matter what the actual
317          effect type is)
318        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
319          note (in this implementation of the sampler its simply hard routed to
320          the 2nd effect send of the sampler channel, no matter what the actual
321          effect type is)
322        - implemented support for internal LADSPA effects
323        - raised limit of program change queue from 100 to 512
324          (as suggested by Alex Stone)
325        - implemented sine LFO, pulse LFO and saw LFO
326        - experimental support for per voice equalization
327        - added command line option --exec-after-init
328        - Introduced new C++ API method:
329          EngineChannel::InstrumentFileName(int index)
330          allowing to retrieve the whole list of files used for the loaded
331          instrument on an engine channel (a.k.a. part). Some GigaStudio
332          instruments for example are splitted over several files like
333          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
334        - Added new C++ API method Sampler::GetGlobalMaxVoices().
335        - Added new C++ API method Sampler::GetGlobalMaxStreams().
336        - Added new C++ API method Sampler::SetGlobalMaxVoices().
337        - Added new C++ API method Sampler::SetGlobalMaxStreams().
338        - Various "const" and "restrict" optimizations.
339        - all engines: add pan CC value to instrument pan parameter before
340          applying panning, instead of using two separate pan functions in
341          series (#182)
342        - added a lock guard class for exception safe mutex handling and
343          used it everywhere appropriate
344        - Immediately apply scale tuning changes to active voices.
345        - Exposed scale tuning to C++ API (along to the already existing standard
346          SysEx way).
347        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
348          and broken for ppc64. (Seq_cst loads and stores are actually not
349          used in LS, so the bug wasn't noticable.)
350        - lsatomic.h: added ARMv7 support
351        - Added support for multiple MIDI input ports per sampler channel (and
352          added various new C++ methods for this new feature / design change, old
353          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
354          as deprecated but are still there and should provide full behavior
355          backward compatibility).
356        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
357          unsafe and caused compilation error with clang 2.x).
358        - Bugfix: only process the latest MIDI program change event.
359        - Introducing the LSCP shell, which provides convenient control of the
360          sampler from the command line by providing LSCP aware features.
361        - VirtualMidiDevice: Added support for program change.
362        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
363        - VirtualMidiDevice: Added support for pitch bend.
364        - Aftertouch: extended API to explicitly handle channel pressure and
365          polyphonic key pressure events (so far polyphonic pressure was not
366          supported at all, and channel pressure was rerouted as CC128 but not
367          used so far).

572          incorrectly set to two. This caused silence in Cubase 5.
573        - save engine type (gig, sfz or sf2) in plugin state
574        - VST: when opening Fantasia, look for both 32 and 64 bit Java on

630        - MME bugfix: driver wasn't closed properly
631        - CoreMIDI: automatically connect to all input sources by default (driver
632          parameter "AUTO_BIND").

769          after MIDI/audio device creation failure
770        - When creating MIDI instrument map entries with "PERSISTENT" type, the
771          instruments were uselessly precached with zero samples, however it still
772          took the full preloading time and on 1st program change the respective
773          instrument was completely reloaded again.
774        - fixed handling of rapid bank select and program change messages
775          sent to the same sampler channel (patch from the Open Octave

791          playing a note in a key group
792        - fixed erroneous error message piping in VoiceBase.h
793          (labelled "Disk stream not available in time")
794        - Update effects on sample rate & period size changes (to avoid
795          crashes and noise on such transitions).
796        - ignore missing LADSPA paths without ignoring valid LADSPA paths
797          (fixes #208)
798        - Fixed bug in LSCP grammar definition which caused a statement like
799          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
800          practically irrelevant, however it caused problems with the new LSCP
801          shell's auto completion feature).
802        - Fixed MIDI program change messages being ignored if quickly executed
803          after each other (fixes #231).

853        - automatic stacktrace mechanism is now turned off by default and can
854          be switched on by command line option "--stacktrace" (the automatic
855          stacktrace mechanism seems to be broken on most systems at the moment)
856        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
857          a pointer to the launched InstrumentEditor object
858        - added optional 3rd party user data parameter for following

881        - added (experimental) CoreAudio driver
882        - applied old fixes to the ASIO driver that were included in the
883          previous binary release but accidentally never committed to CVS
884          (fixes #117)
885        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
886          win64)

900          exception when getting parameters from a disconnected device
901    
902      * MIDI driver:
903        - added JACK MIDI driver
904        - dispatch bank select as ordinary CC as well, the user might seriously

922          instrument database compilable
923        - added instrument database support on Windows
924          works with both standalone mode and VST plugin.
925          the instruments DB file is located in
926          %USERPROFILE%\.linuxsampler\instruments.db which allows different
927          databases for each windows user
928          if no DB is present it automatically creates the .linuxsampler subdir
929          and then creates an empty DB
930        - fixed recursive import, which was broken on Windows
931    
932    * Gigasampler format engine:    * Gigasampler format engine:

934        while notes were playing        while notes were playing
935        - made it possible to load an instrument even if the audio thread
936          isn't running
937        - added partial support for the "Controller Triggered" MIDI rule,
938          enough for piano gigs with pedal noise samples
939        - minor fix: only mark FX sends as being modified if really the
940          respective FX send MIDI controller was used
941        - added support for GM global device volume SysEx message
942          (can be selected at compile time to either apply globally to the
943          whole sampler [default] or only to the sampler channels that are
944          connected to the respective MIDI input port the SysEx message arrived
945          on)
946        - bugfix: notes triggered at position 0 in the audio buffer were
947          sometimes wrongly killed in the same buffer, causing no sound to
948          be played
949        - added support for chromatic / drumkit mode Roland GS Sysex message
950          which is usally used to switch a part between chromatic sounds and
951          drumkit sounds (as opposed to their common default setting of MIDI
952          part 10 being a drumkit part and all other ones chromatic parts), in
953          LS however one can switch between the first 16 MIDI instrument maps
954          defined for the sampler
955        - made it possible to create multiple sample channels even if the
956          audio thread isn't running
957        - fixed crash when removing channel with active voices (#116)
958        - bugfix: on sample reference changes (instrument editor), only
959          un-cache the respective sample if it's really not used by any
960          sampler engine anymore
961        - re-cache samples in case they were changed by an instrument editor,
962          e.g. when a sample was added while playing (#82)
963        - fixed hanging notes which occured when note-off event had the exact
964          same time stamp as the voice's note-on event and occured both in the
965          same audio fragment cycle (fixes bug #112)
966        - added support for the "fine tune" and "pitch bend range"
967          instrument-level gig parameters
968        - fixed minor artifacts in pitch bend handling
969        - added support for GS Reset SysEx message
970        - allow gig files to use unlimited downward pitch shifting
971        - added a limit check for upward pitch shifting
972        - bugfix: sometimes, when playing a note twice fast, the second
973          note was silent
974        - fixed crash happening when a pitch bend event arrived at the
975          same time a new instrument was loading
976    
977      * LSCP server:
978        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
979          react on MIDI data arriving on certain sampler channels (so far only
980          Note-On and Note-Off events are sent via this LSCP event)
981        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
982          react on MIDI data arriving on certain MIDI input devices (so far only
983          Note-On and Note-Off events are sent via this LSCP event)
984        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
985          SET DB_INSTRUMENT FILE_PATH
986        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
987          frontends to send MIDI messages to specific sampler channel
988        - added two additional fields to GET FILE INSTRUMENT INFO command -
989          KEY_BINDINGS and KEYSWITCH_BINDINGS
990        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
991          was incorrect
992        - Optimized the retrieval of the MIDI instrument mappings
993        - added new LSCP command "SET VOICES" to globally alter the maximum
994          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
995          be triggered respectively
996        - added new LSCP command "SET STREAMS" to globally alter the maximum
997          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
998          which will be triggered respectively
999        - bugfix: retry if "select" returns EINTR (this fixes a crash when
1000          a gigedit file dialog is opened)
1001        - close all connections when LSCPServer is deleted
1002        - hard close of all sockets on exit
1003        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1004          driver
1005    
1006      * Bug fixes:
1007        - fixed a crash which occurs when removing a sampler channel waiting

1017          GET MIDI_INPUT_DRIVER INFO
1018          GET MIDI_INPUT_DRIVER_PARAMETER INFO
1019        - fixed possible compilation error when sqlite is not present
1020        - fixed orphaned pointers when setting maximum voices limit (bug #118)
1021        - fixed crash when changing the audio output device of a sampler
1022          channel with loaded instrument and start playing notes
1023        - fixed endless loop in Engine::SuspendAll() (bug #120)
1024        - fixed a low-level atomic load function that was broken on 64-bit
1025          PowerPC, which probably could cause crashes on that platform
1026        - fixed a memory management error which could cause a crash when a
1027          plugin was unloaded
1028        - bugfix: two private structs had the same name, which could cause
1029          problems if the linker chose the wrong constructor
1030        - fixed low-level ConditionServer usage bug that caused lockups on
1031          Windows
