# Line 1  Line 1 
1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3    * plugin changes:    * SFZ format engine:
4      - LV2 Persist + Files support (patch by David Robillard)      - 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    
20      * general changes:
21        - fixed printf type errors (mostly in debug messages)
22        - use unique_ptr instead of auto_ptr when building with C++11
23        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
24          allowing to sort data efficiently in real-time safe manner.
25        - RTList class: added methods for moving/inserting elements to arbitrary
26          position within a list.
27        - RTList class: added method fromPtr() for creating an Iterator object from
28          a raw element pointer.
29        - Attempt to partly fix resetting engine channels vs. resetting engine, an
30          overall cleanup of the Reset*(), ConnectAudioDevice(),
31          DisconnectAudioDevice() API methods would still be desirable though,
32          because the current situation is still inconsistent and error prone.
33        - Active voices are now internally grouped to "Note" objects, instead of
34          being directly assigned to a keyboard key. This allows more fine graded
35          processing of voices, which is i.e. required for certain instrument
36          script features.
37        - Fix: Release trigger voices were not spawned on sustain pedal up
38          (CC #64) events.
39        - Fix: Release trigger voices can now also distinguish correctly between
40          note-off and sustain pedal up events.
41        - All engines: Increased ramp speed of volume smoother and pan smoother
42          (while slow rate of crossfade smoother is preserved) to allow quick
43          volume and pan changes by instrument scripts for instance.
44        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
45          properly and thus were ignored for certain uses.
46        - Added new C++ API method
47          VirtualMidiDevice::SendChannelPressureToSampler().
48        - windows, 32-bit: fixed potential crashes by making sure the stack in
49          sub threads is 16-byte aligned
50        - fixed numerous compiler warnings
51        - Fixed invalid (note-on) event ID being assigned to new Note objects.
52        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
53          fixes potential undefined behavior.
54    
55      * packaging changes:
56        - removed unnecessary dependency to libuuid
57          (originated by libgig's usage of it)
58        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
59          auto detect whether it (sh/c)ould output its messages in color.
60    
61      * Real-time instrument scripts:
62        - Implemented scheduler for delayed MIDI events and for suspended scripts.
63        - Built-in script function "wait()": implemented support for function's
64          "duration-us" argument, thus scripts using this function are now
65          correctly resumed after the requested amount of microseconds.
66        - Built-in script function "play_note()": implemented support for
67          function's "duration-us" argument, thus notes triggered with this
68          argument are now correctly released after the requested amount of
69          microseconds.
70        - Fix: script events were not cleared when engine channel was reset,
71          potentially causing undefined behavior.
72        - Fixed crash which happened when trying to reference an undeclared
73          variable.
74        - Built-in script function "play_note()": Added support for passing
75          special value -1 for "duration-us" argument, which will cause the
76          triggered note to be released once the original note was released.
77        - Instrument script classes now exported with the liblinuxsampler C++ API.
78        - Added new API method ScriptVM::syntaxHighlighting() which provides
79          a convenient syntax highlighting backend for external instrument
80          script editor applications.
81        - Added new C++ API class "ScriptVMFactory".
82        - Extended parser issues to provide not only first line and first
83          column, but also last line and last column of issue (thus marking
84          the precise span of the issue within the source code).
85        - Reload script automatically after being modified by an instrument
86          editor.
87        - NKSP language grammar correction: allow empty event handler bodies
88          like "on note end on".
89        - Implemented built-in script function "change_vol()".
90        - Implemented built-in script function "change_tune()".
91        - Implemented built-in script function "change_pan()".
92        - Implemented built-in script function "change_cutoff()".
93        - Implemented built-in script function "change_reso()".
94        - Implemented built-in script function "event_status()".
95        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
96          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
97          "event_status()" function.
98        - NKSP language: Added support for bitwise operators ".or.", ".and."
99          and ".not.".
100        - NKSP language scanner: Fixed IDs matching to require at least one
101          character (i.e. when matching function names or variable names).
102        - NKSP language scanner: disabled unusued rules.
103        - Fixed behavior of play_note() and note_off() functions which must
104          be distinguished engine internally from "real" MIDI note on/off
105          events in order to avoid misbehaviors like hanging notes.
106        - Implemented built-in script variable "$KSP_TIMER".
107        - Implemented built-in script variable "$NKSP_REAL_TIMER".
108        - Implemented built-in script variable "$NKSP_PERF_TIMER".
109        - Implemented built-in script variable "$ENGINE_UPTIME".
110        - Implemented built-in script function "inc()".
111        - Implemented built-in script function "dec()".
112        - NKSP language fix: division expressions were evaluated too often.
113        - NKSP language fix: string concatenation operator was right
114          associative instead of left (to right).
115        - NKSP language correction: allow empty statements in entire language
116          (i.e. "if end if").
117        - Implemented built-in script function "stop_wait()".
118        - Implemented built-in script variable "$NI_CALLBACK_ID".
119        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
120        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
121        - Added support for read-only built-in variables (respectively
122          handled by the script parser).
123        - Added built-in script constant "$NI_CB_TYPE_INIT".
124        - Added built-in script constant "$NI_CB_TYPE_NOTE".
125        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
126        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
127        - NKSP Language: Added support for user defined script functions.
128        - Implemented built-in script function "change_attack()".
129        - Implemented built-in script function "change_decay()".
130        - Implemented built-in script function "change_release()".
131        - Fixed all change_*() built-in script functions to apply their
132          synthesis parameter changes immediately in case the respective note
133          was triggered at the same time, instead of scheduling the parameter
134          change, especially because it would cause some parameter types's
135          changes either to be ramped (i.e. change_vol()) or other types even
136          to have not effect at all (i.e. change_attack()).
137        - Implemented built-in script function "sh_left()".
138        - Implemented built-in script function "sh_right()".
139        - Implemented built-in script function "min()".
140        - Implemented built-in script function "max()".
141        - NKSP Fix: "init" event handler was not always executed when a script
142          was loaded.
143        - NKSP built-in wait() script function: abort script execution if
144          a negative or zero wait time was passed as argument (since this is
145          a common indication of a bug either of the script or even of the
146          engine, which could lead to RT instability or even worse).
147        - ScriptVM: Implemented automatic suspension of RT safety
148          threatening scripts.
149        - Provide more user friendly error messages on syntax errors.
150        - Fixed NKSP parser warning "Not a statement" when assigning an
151          initializer list to an array variable.
152        - Implemented built-in script array variable "%ALL_EVENTS".
153        - Implemented built-in script function "in_range()".
154        - Implemented built-in script function "change_amp_lfo_depth()".

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

301      - implemented sine LFO, pulse LFO and saw LFO      - implemented sine LFO, pulse LFO and saw LFO
302        - experimental support for per voice equalization
303        - added command line option --exec-after-init
304        - Introduced new C++ API method:
305          EngineChannel::InstrumentFileName(int index)
306          allowing to retrieve the whole list of files used for the loaded
307          instrument on an engine channel (a.k.a. part). Some GigaStudio
308          instruments for example are splitted over several files like
309          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
310        - Added new C++ API method Sampler::GetGlobalMaxVoices().
311        - Added new C++ API method Sampler::GetGlobalMaxStreams().
312        - Added new C++ API method Sampler::SetGlobalMaxVoices().
313        - Added new C++ API method Sampler::SetGlobalMaxStreams().
314        - Various "const" and "restrict" optimizations.
315        - all engines: add pan CC value to instrument pan parameter before
316          applying panning, instead of using two separate pan functions in
317          series (#182)
318        - added a lock guard class for exception safe mutex handling and
319          used it everywhere appropriate
320        - Immediately apply scale tuning changes to active voices.
321        - Exposed scale tuning to C++ API (along to the already existing standard
322          SysEx way).
323        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
324          and broken for ppc64. (Seq_cst loads and stores are actually not
325          used in LS, so the bug wasn't noticable.)
326        - lsatomic.h: added ARMv7 support
327        - Added support for multiple MIDI input ports per sampler channel (and
328          added various new C++ methods for this new feature / design change, old
329          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
330          as deprecated but are still there and should provide full behavior
331          backward compatibility).
332        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
333          unsafe and caused compilation error with clang 2.x).
334        - Bugfix: only process the latest MIDI program change event.
335        - Introducing the LSCP shell, which provides convenient control of the
336          sampler from the command line by providing LSCP aware features.
337        - VirtualMidiDevice: Added support for program change.
338        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
339        - VirtualMidiDevice: Added support for pitch bend.
340        - Aftertouch: extended API to explicitly handle channel pressure and
341          polyphonic key pressure events (so far polyphonic pressure was not
342          supported at all, and channel pressure was rerouted as CC128 but not
343          used so far).
344        - Added initial support for real-time instrument scripts. The script VM
345          code is shared by all sampler engine implemementations, however only the
346          gig file format currently provides support for storing instrument scripts
347          (as LinuxSampler extension to the original GigaStudio 4 format).

357        - filter performance fix (an unnecessary copy was made of the
358          filter parameters in each sub fragment)
359        - handle special case when pan parameter in gig file has max or
360          min value
361        - Exclusive Groups: don't ever stop voices of the same note,
362          doesn't sound naturally with a drumkit
363        - fixed EG1 modulation when attack or release is zero
364        - Fixed support for 'aftertouch' attenuation controller.
365        - Fixed crash that happened with velocity split sounds under certain
366          conditions (see also previous commit on libgig).
367        - fixed behaviour of filter LFO
