# 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        - linuxsampler binary fix: option --create-instruments-db ignored
61          subsequent optional argument due to glibc's implementation oddity
62          which expects a "=" sign, but no space between them.
63    
64      * packaging changes:
65        - removed unnecessary dependency to libuuid
66          (originated by libgig's usage of it)
67        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
68          auto detect whether it (sh/c)ould output its messages in color.
69        - Debian: Fixed packaging error about invalid "Source-Version"
70          substitution variable.
71        - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
72        - Debian: Added build dependency to libsqlite3-dev for building
73          linuxsampler with instruments DB support.
74    
75      * Real-time instrument scripts:
76        - Implemented scheduler for delayed MIDI events and for suspended scripts.
77        - Built-in script function "wait()": implemented support for function's
78          "duration-us" argument, thus scripts using this function are now
79          correctly resumed after the requested amount of microseconds.
80        - Built-in script function "play_note()": implemented support for
81          function's "duration-us" argument, thus notes triggered with this
82          argument are now correctly released after the requested amount of
83          microseconds.
84        - Fix: script events were not cleared when engine channel was reset,
85          potentially causing undefined behavior.
86        - Fixed crash which happened when trying to reference an undeclared
87          variable.
88        - Built-in script function "play_note()": Added support for passing
89          special value -1 for "duration-us" argument, which will cause the
90          triggered note to be released once the original note was released.
91        - Instrument script classes now exported with the liblinuxsampler C++ API.
92        - Added new API method ScriptVM::syntaxHighlighting() which provides
93          a convenient syntax highlighting backend for external instrument
94          script editor applications.
95        - Added new C++ API class "ScriptVMFactory".
96        - Extended parser issues to provide not only first line and first
97          column, but also last line and last column of issue (thus marking
98          the precise span of the issue within the source code).
99        - Reload script automatically after being modified by an instrument
100          editor.
101        - NKSP language grammar correction: allow empty event handler bodies
102          like "on note end on".
103        - Implemented built-in script function "change_vol()".
104        - Implemented built-in script function "change_tune()".
105        - Implemented built-in script function "change_pan()".
106        - Implemented built-in script function "change_cutoff()".
107        - Implemented built-in script function "change_reso()".
108        - Implemented built-in script function "event_status()".
109        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
110          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
111          "event_status()" function.
112        - NKSP language: Added support for bitwise operators ".or.", ".and."
113          and ".not.".
114        - NKSP language scanner: Fixed IDs matching to require at least one
115          character (i.e. when matching function names or variable names).
116        - NKSP language scanner: disabled unusued rules.
117        - Fixed behavior of play_note() and note_off() functions which must
118          be distinguished engine internally from "real" MIDI note on/off
119          events in order to avoid misbehaviors like hanging notes.
120        - Implemented built-in script variable "$KSP_TIMER".
121        - Implemented built-in script variable "$NKSP_REAL_TIMER".
122        - Implemented built-in script variable "$NKSP_PERF_TIMER".
123        - Implemented built-in script variable "$ENGINE_UPTIME".
124        - Implemented built-in script function "inc()".
125        - Implemented built-in script function "dec()".
126        - NKSP language fix: division expressions were evaluated too often.
127        - NKSP language fix: string concatenation operator was right
128          associative instead of left (to right).
129        - NKSP language correction: allow empty statements in entire language
130          (i.e. "if end if").
131        - Implemented built-in script function "stop_wait()".
132        - Implemented built-in script variable "$NI_CALLBACK_ID".
133        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
134        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
135        - Added support for read-only built-in variables (respectively
136          handled by the script parser).
137        - Added built-in script constant "$NI_CB_TYPE_INIT".
138        - Added built-in script constant "$NI_CB_TYPE_NOTE".
139        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
140        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".

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

170        - Implemented built-in script function "change_pitch_lfo_depth()".
171        - Implemented built-in script function "change_pitch_lfo_freq()".
172        - Implemented built-in script function "change_vol_time()".
173        - Implemented built-in script function "change_tune_time()".
174        - Implemented built-in script function "fade_in()".
175        - Implemented built-in script function "fade_out()".
176        - Fixed acceptance of wrong data type of parameters passed to built-in
177          script functions "change_vol()", "change_tune()", "change_pan()",
178          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
179          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
180          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
181        - Added built-in script function "get_event_par()" and implemented some
182          of its possible parameter selections.
183        - Added built-in script function "set_event_par()" and implemented some
184          of its possible parameter selections.
185        - Fixed a bunch of scheduler time related bugs.
186        - Fixed polyphonic variables not being reset to zero after usage.
187        - Built-in "ignore_event()" function: argument is now optional, like with
188          built-in function "ignore_controller()".
189        - Implemented built-in script function "change_velo()".
190        - Implemented built-in script function "change_note()".
191        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
192          intuitive behavior if used in combination with "change_vol_time()" or
193          "change_tune_time()" respectively: now tuning/volume changes are only
194          assigned (without delay) immediately to a new note if the respective
195          timing function has not been called before, otherwise the volume/tuning
196          changes are automatically faded (before, only the event's time stamp was
197          relevant).
198         - Implemented built-in script function "array_equal()".
199         - Implemented built-in script function "search()".
200         - Implemented built-in script function "sort()".
201         - NKSP Fix: Never suspend "init" event handlers.
202         - Implemented built-in script function "same_region()" (currently only
203           available for gig format engine).
204         - Added built-in script constant "$NKSP_LINEAR".
205         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
206         - Implemented built-in script function "change_vol_curve()".
207         - Implemented built-in script function "change_tune_curve()".
208         - built-in "play_note()" function now supports a sample playback start
209           offset with argument 3, where special value -1 means to use the regular
210           sample offset as defined by the instrument file.
211         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
212         - Built-in variable $EVENT_NOTE is now a read-only variable.
213         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
214         - built-in "play_note()" function now accepts -2 for its fourth argument
215           (note duration) which means the life time of the note shall be sticked
216           to the requested note number of argument 1.
217         - Fix: built-in "play_note()" function now returns 0 as result value if
218           -1 was passed for its fourth argument (note duration) and the respective
219           parent note is already gone.
220        - Implemented built-in script function "change_play_pos()".
221        - NKSP language: Added support for user declared const array variables.
222        - NKSP language: Raise parser warning if array variable is accessed with
223          an index that exceeds the array's size.
224        - NKSP language fix: Unknown characters were not handled correctly.
225        - NKSP language: Added support for "synchronized .. end synchronized"
226          code blocks.
227        - Implemented built-in script function "abort()" which allows to abort
228          another script handler by passing its callback ID.
229        - Fixed potential memory access bug and potential undefined behavior of
230          "init" event handlers.
231        - Print a time stamp along to each call of built-in function "message()".
232        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
233          to retrieve all code blocks filtered out by the preprocessor.
234        - Added built-in script function "fork()".
235        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
236        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
237        - Fixed potential crash when accessing dynamic built-in array variables.
238        - Added built-in script function "callback_status()".
239        - Added built-in constant $CALLBACK_STATUS_TERMINATED.
240        - Added built-in constant $CALLBACK_STATUS_QUEUE.
241        - Added built-in constant $CALLBACK_STATUS_RUNNING.
242        - Removed max. value limitation of built-in functions "change_attack()",
243          "change_decay()" and "change_release()" to i.e. allow passing 2000000
244          for doubling the respective time.
245        - NKSP script editor syntax highlighting API: Fixed app termination due
246          to a lexer start condition stack underrun.
247        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
248          USE_CODE_IF_NOT() preprocessor statements.
249        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
250          can be set to disable all subsequent built-in "message()" function calls
251          on preprocessor level.
252        - Implemented built-in script function "change_sustain()".
253        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
254          to avoid the editor app to crash on ill-formed text input.
255        - Added built-in script function "change_pan_time()".
256        - Added built-in script function "change_pan_curve()".
257    
258      * Instruments DB:
259        - Fixed memory access bug of general DB access code which lead to
260          undefined behavior.
261        - Cleanup of instruments DB file creation and opening code.
262        - The instrument DB path of linuxsampler's --create-instruments-db argument
263          is now optional, if it is missing, then a default location is used.
264        - Added support for scanning SFZ (.sfz) files.
265        - Added support for scanning Sound Font (.sf2) files.
266        - Fixed undefined DB transaction behavior.
267

272        - Mac OS X: support the new dir for Core Audio SDK
273        - Mac OS X: fixed building outside source directory
274        - made sure all source files for hostplugins are included when
275          doing "make dist"
276        - removed empty directories left from the cvs to svn migration
277        - fixed compilation with gcc 4.6.1
278        - another "make dist" fix, for the LV2 plugin
279        - made --enable-pthread-testcancel default on Mac OS X
280        - minor Makefile fix for building lscpparser when build and source
281          directories are separate
282        - Mac OS X: made it possible to specify plugin installation dir to
283          configure
284        - Mac OS X: Makefile fix for the install-strip target
285        - fixed compilation with gcc 4.7
286        - fixed configure script error with old autoconf versions

288          gcc 4.7 and C++11
289        - modernized configure script
290        - fixed linkage error when building with
291          LDFLAGS="-Wl,--no-undefined" (#190)
292        - fixed compilation with Clang 3.2

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

371          supported at all, and channel pressure was rerouted as CC128 but not
372          used so far).
373        - Added initial support for real-time instrument scripts. The script VM
374          code is shared by all sampler engine implemementations, however only the
375          gig file format currently provides support for storing instrument scripts
376          (as LinuxSampler extension to the original GigaStudio 4 format).

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

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

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

800          crashes and noise on such transitions).
801        - ignore missing LADSPA paths without ignoring valid LADSPA paths
802          (fixes #208)
803        - Fixed bug in LSCP grammar definition which caused a statement like
804          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
805          practically irrelevant, however it caused problems with the new LSCP
806          shell's auto completion feature).
807        - Fixed MIDI program change messages being ignored if quickly executed
808          after each other (fixes #231).

927          instrument database compilable
928        - added instrument database support on Windows
929          works with both standalone mode and VST plugin.
930          the instruments DB file is located in
931          %USERPROFILE%\.linuxsampler\instruments.db which allows different
932          databases for each windows user
933          if no DB is present it automatically creates the .linuxsampler subdir

942        - added partial support for the "Controller Triggered" MIDI rule,
943          enough for piano gigs with pedal noise samples

946        - added support for GM global device volume SysEx message
947          (can be selected at compile time to either apply globally to the
948          whole sampler [default] or only to the sampler channels that are
949          connected to the respective MIDI input port the SysEx message arrived
950          on)
951        - bugfix: notes triggered at position 0 in the audio buffer were
952          sometimes wrongly killed in the same buffer, causing no sound to
953          be played
954        - added support for chromatic / drumkit mode Roland GS Sysex message
955          which is usally used to switch a part between chromatic sounds and
956          drumkit sounds (as opposed to their common default setting of MIDI
957          part 10 being a drumkit part and all other ones chromatic parts), in
958          LS however one can switch between the first 16 MIDI instrument maps
959          defined for the sampler

969          same time stamp as the voice's note-on event and occured both in the
970          same audio fragment cycle (fixes bug #112)
971        - added support for the "fine tune" and "pitch bend range"
972          instrument-level gig parameters
973        - fixed minor artifacts in pitch bend handling
974        - added support for GS Reset SysEx message
975        - allow gig files to use unlimited downward pitch shifting
976        - added a limit check for upward pitch shifting
977        - bugfix: sometimes, when playing a note twice fast, the second
978          note was silent
979        - fixed crash happening when a pitch bend event arrived at the
980          same time a new instrument was loading

986        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
987          react on MIDI data arriving on certain MIDI input devices (so far only
988          Note-On and Note-Off events are sent via this LSCP event)
989        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
990          SET DB_INSTRUMENT FILE_PATH
991        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
992          frontends to send MIDI messages to specific sampler channel
993        - added two additional fields to GET FILE INSTRUMENT INFO command -
994          KEY_BINDINGS and KEYSWITCH_BINDINGS
995        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
996          was incorrect
997        - Optimized the retrieval of the MIDI instrument mappings
998        - added new LSCP command "SET VOICES" to globally alter the maximum
999          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1000          be triggered respectively

1032          plugin was unloaded
1033        - bugfix: two private structs had the same name, which could cause
