# 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    
11      * Gigasampler/GigaStudio format engine:
12        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
13          cutoff settings.
14    
15      * general changes:
16        - fixed printf type errors (mostly in debug messages)
17        - use unique_ptr instead of auto_ptr when building with C++11
18        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
19          allowing to sort data efficiently in real-time safe manner.
20        - RTList class: added methods for moving/inserting elements to arbitrary
21          position within a list.
22        - RTList class: added method fromPtr() for creating an Iterator object from
23          a raw element pointer.
24        - Attempt to partly fix resetting engine channels vs. resetting engine, an
25          overall cleanup of the Reset*(), ConnectAudioDevice(),
26          DisconnectAudioDevice() API methods would still be desirable though,
27          because the current situation is still inconsistent and error prone.
28        - Active voices are now internally grouped to "Note" objects, instead of
29          being directly assigned to a keyboard key. This allows more fine graded
30          processing of voices, which is i.e. required for certain instrument
31          script features.
32        - Fix: Release trigger voices were not spawned on sustain pedal up
33          (CC #64) events.
34        - Fix: Release trigger voices can now also distinguish correctly between
35          note-off and sustain pedal up events.
36        - All engines: Increased ramp speed of volume smoother and pan smoother
37          (while slow rate of crossfade smoother is preserved) to allow quick
38          volume and pan changes by instrument scripts for instance.
39        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
40          properly and thus were ignored for certain uses.
41        - Added new C++ API method
42          VirtualMidiDevice::SendChannelPressureToSampler().
43        - windows, 32-bit: fixed potential crashes by making sure the stack in
44          sub threads is 16-byte aligned
45        - fixed numerous compiler warnings
46        - Fixed invalid (note-on) event ID being assigned to new Note objects.
47        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
48          fixes potential undefined behavior.
49    
50      * packaging changes:
51        - removed unnecessary dependency to libuuid
52          (originated by libgig's usage of it)
53        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
54          auto detect whether it (sh/c)ould output its messages in color.
55    
56      * Real-time instrument scripts:
57        - Implemented scheduler for delayed MIDI events and for suspended scripts.
58        - Built-in script function "wait()": implemented support for function's
59          "duration-us" argument, thus scripts using this function are now
60          correctly resumed after the requested amount of microseconds.
61        - Built-in script function "play_note()": implemented support for
62          function's "duration-us" argument, thus notes triggered with this
63          argument are now correctly released after the requested amount of
64          microseconds.
65        - Fix: script events were not cleared when engine channel was reset,
66          potentially causing undefined behavior.
67        - Fixed crash which happened when trying to reference an undeclared
68          variable.
69        - Built-in script function "play_note()": Added support for passing
70          special value -1 for "duration-us" argument, which will cause the
71          triggered note to be released once the original note was released.
72        - Instrument script classes now exported with the liblinuxsampler C++ API.
73        - Added new API method ScriptVM::syntaxHighlighting() which provides
74          a convenient syntax highlighting backend for external instrument
75          script editor applications.
76        - Added new C++ API class "ScriptVMFactory".
77        - Extended parser issues to provide not only first line and first
78          column, but also last line and last column of issue (thus marking
79          the precise span of the issue within the source code).
80        - Reload script automatically after being modified by an instrument
81          editor.
82        - NKSP language grammar correction: allow empty event handler bodies
83          like "on note end on".
84        - Implemented built-in script function "change_vol()".
85        - Implemented built-in script function "change_tune()".
86        - Implemented built-in script function "change_pan()".
87        - Implemented built-in script function "change_cutoff()".
88        - Implemented built-in script function "change_reso()".
89        - Implemented built-in script function "event_status()".
90        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
91          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
92          "event_status()" function.
93        - NKSP language: Added support for bitwise operators ".or.", ".and."
94          and ".not.".
95        - NKSP language scanner: Fixed IDs matching to require at least one
96          character (i.e. when matching function names or variable names).
97        - NKSP language scanner: disabled unusued rules.
98        - Fixed behavior of play_note() and note_off() functions which must
99          be distinguished engine internally from "real" MIDI note on/off
100          events in order to avoid misbehaviors like hanging notes.
101        - Implemented built-in script variable "$KSP_TIMER".
102        - Implemented built-in script variable "$NKSP_REAL_TIMER".
103        - Implemented built-in script variable "$NKSP_PERF_TIMER".
104        - Implemented built-in script variable "$ENGINE_UPTIME".
105        - Implemented built-in script function "inc()".
106        - Implemented built-in script function "dec()".
107        - NKSP language fix: division expressions were evaluated too often.
108        - NKSP language fix: string concatenation operator was right
109          associative instead of left (to right).
110        - NKSP language correction: allow empty statements in entire language
111          (i.e. "if end if").
112        - Implemented built-in script function "stop_wait()".
113        - Implemented built-in script variable "$NI_CALLBACK_ID".
114        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
115        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
116        - Added support for read-only built-in variables (respectively
117          handled by the script parser).
118        - Added built-in script constant "$NI_CB_TYPE_INIT".
119        - Added built-in script constant "$NI_CB_TYPE_NOTE".
120        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
121        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
122        - NKSP Language: Added support for user defined script functions.
123        - Implemented built-in script function "change_attack()".
124        - Implemented built-in script function "change_decay()".
125        - Implemented built-in script function "change_release()".
126        - Fixed all change_*() built-in script functions to apply their
127          synthesis parameter changes immediately in case the respective note
128          was triggered at the same time, instead of scheduling the parameter
129          change, especially because it would cause some parameter types's
130          changes either to be ramped (i.e. change_vol()) or other types even
131          to have not effect at all (i.e. change_attack()).
132        - Implemented built-in script function "sh_left()".
133        - Implemented built-in script function "sh_right()".
134        - Implemented built-in script function "min()".
135        - Implemented built-in script function "max()".
136        - NKSP Fix: "init" event handler was not always executed when a script
137          was loaded.
138        - NKSP built-in wait() script function: abort script execution if
139          a negative or zero wait time was passed as argument (since this is
140          a common indication of a bug either of the script or even of the
141          engine, which could lead to RT instability or even worse).
142        - ScriptVM: Implemented automatic suspension of RT safety
143          threatening scripts.
144        - Provide more user friendly error messages on syntax errors.
145        - Fixed NKSP parser warning "Not a statement" when assigning an
146          initializer list to an array variable.
147        - Implemented built-in script array variable "%ALL_EVENTS".
148        - Implemented built-in script function "in_range()".
149        - Implemented built-in script function "change_amp_lfo_depth()".

151        - Implemented built-in script function "change_pitch_lfo_depth()".
152        - Implemented built-in script function "change_pitch_lfo_freq()".
153        - Implemented built-in script function "change_vol_time()".
154        - Implemented built-in script function "change_tune_time()".
155        - Implemented built-in script function "fade_in()".
156        - Implemented built-in script function "fade_out()".
157        - Fixed acceptance of wrong data type of parameters passed to built-in
158          script functions "change_vol()", "change_tune()", "change_pan()",
159          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
160          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
161          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
162        - Added built-in script function "get_event_par()" and implemented some
163          of its possible parameter selections.
164        - Added built-in script function "set_event_par()" and implemented some
165          of its possible parameter selections.
166        - Fixed a bunch of scheduler time related bugs.
167        - Fixed polyphonic variables not being reset to zero after usage.
168        - Built-in "ignore_event()" function: argument is now optional, like with
169          built-in function "ignore_controller()".
170        - Implemented built-in script function "change_velo()".
171        - Implemented built-in script function "change_note()".
172        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
173          intuitive behavior if used in combination with "change_vol_time()" or
174          "change_tune_time()" respectively: now tuning/volume changes are only
175          assigned (without delay) immediately to a new note if the respective
176          timing function has not been called before, otherwise the volume/tuning
177          changes are automatically faded (before, only the event's time stamp was
178          relevant).
179         - Implemented built-in script function "array_equal()".
180         - Implemented built-in script function "search()".
181         - Implemented built-in script function "sort()".
182         - NKSP Fix: Never suspend "init" event handlers.
183         - Implemented built-in script function "same_region()" (currently only
184           available for gig format engine).
185         - Added built-in script constant "$NKSP_LINEAR".
186         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
187         - Implemented built-in script function "change_vol_curve()".
188         - Implemented built-in script function "change_tune_curve()".
189         - built-in "play_note()" function now supports a sample playback start
190           offset with argument 3, where special value -1 means to use the regular
191           sample offset as defined by the instrument file.
192         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
193         - Built-in variable $EVENT_NOTE is now a read-only variable.
194         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
195         - built-in "play_note()" function now accepts -2 for its fourth argument
196           (note duration) which means the life time of the note shall be sticked
197           to the requested note number of argument 1.
198         - Fix: built-in "play_note()" function now returns 0 as result value if
199           -1 was passed for its fourth argument (note duration) and the respective
200           parent note is already gone.
201        - Implemented built-in script function "change_play_pos()".
202        - NKSP language: Added support for user declared const array variables.
203        - NKSP language: Raise parser warning if array variable is accessed with
204          an index that exceeds the array's size.
205        - NKSP language fix: Unknown characters were not handled correctly.
206        - NKSP language: Added support for "synchronized .. end synchronized"
207          code blocks.

209          another script handler by passing its callback ID.
210        - Fixed potential memory access bug and potential undefined behavior of
211          "init" event handlers.
212        - Print a time stamp along to each call of built-in function "message()".
213        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
214          to retrieve all code blocks filtered out by the preprocessor.
215    
216      * Instruments DB:
217        - Fixed memory access bug of general DB access code which lead to
218          undefined behavior.
219        - Cleanup of instruments DB file creation and opening code.
220        - The instrument DB path of linuxsampler's --create-instruments-db argument
221          is now optional, if it is missing, then a default location is used.
222        - Added support for scanning SFZ (.sfz) files.
223        - Added support for scanning Sound Font (.sf2) files.
224        - Fixed undefined DB transaction behavior.

285      - implemented support for internal LADSPA effects      - implemented support for internal LADSPA effects
286      - raised limit of program change queue from 100 to 512      - raised limit of program change queue from 100 to 512
287        (as suggested by Alex Stone)        (as suggested by Alex Stone)
288        - implemented sine LFO, pulse LFO and saw LFO
289        - experimental support for per voice equalization
290        - added command line option --exec-after-init
291        - Introduced new C++ API method:
292          EngineChannel::InstrumentFileName(int index)
293          allowing to retrieve the whole list of files used for the loaded
294          instrument on an engine channel (a.k.a. part). Some GigaStudio
295          instruments for example are splitted over several files like
296          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
297        - Added new C++ API method Sampler::GetGlobalMaxVoices().
298        - Added new C++ API method Sampler::GetGlobalMaxStreams().
299        - Added new C++ API method Sampler::SetGlobalMaxVoices().
300        - Added new C++ API method Sampler::SetGlobalMaxStreams().
301        - Various "const" and "restrict" optimizations.
302        - all engines: add pan CC value to instrument pan parameter before
303          applying panning, instead of using two separate pan functions in
304          series (#182)
305        - added a lock guard class for exception safe mutex handling and
306          used it everywhere appropriate
307        - Immediately apply scale tuning changes to active voices.
308        - Exposed scale tuning to C++ API (along to the already existing standard
309          SysEx way).
310        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
311          and broken for ppc64. (Seq_cst loads and stores are actually not
312          used in LS, so the bug wasn't noticable.)
313        - lsatomic.h: added ARMv7 support
314        - Added support for multiple MIDI input ports per sampler channel (and
315          added various new C++ methods for this new feature / design change, old
316          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
317          as deprecated but are still there and should provide full behavior
318          backward compatibility).
319        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
320          unsafe and caused compilation error with clang 2.x).
321        - Bugfix: only process the latest MIDI program change event.
322        - Introducing the LSCP shell, which provides convenient control of the
323          sampler from the command line by providing LSCP aware features.
324        - VirtualMidiDevice: Added support for program change.
325        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
326        - VirtualMidiDevice: Added support for pitch bend.
327        - Aftertouch: extended API to explicitly handle channel pressure and
328          polyphonic key pressure events (so far polyphonic pressure was not
329          supported at all, and channel pressure was rerouted as CC128 but not
330          used so far).
331        - Added initial support for real-time instrument scripts. The script VM
332          code is shared by all sampler engine implemementations, however only the
333          gig file format currently provides support for storing instrument scripts
334          (as LinuxSampler extension to the original GigaStudio 4 format).
335    
336    * Gigasampler format engine:    * Gigasampler format engine:
337      - implemented the "round robin keyboard" dimension      - implemented the "round robin keyboard" dimension

342        - bugfix: pitch LFO controller "internal+aftertouch" was broken
343        - bugfix: filter keyboard tracking was broken
344        - filter performance fix (an unnecessary copy was made of the
345          filter parameters in each sub fragment)
346        - handle special case when pan parameter in gig file has max or
347          min value
348        - Exclusive Groups: don't ever stop voices of the same note,
349          doesn't sound naturally with a drumkit
350        - fixed EG1 modulation when attack or release is zero
351        - Fixed support for 'aftertouch' attenuation controller.
352        - Fixed crash that happened with velocity split sounds under certain
353          conditions (see also previous commit on libgig).
354        - fixed behaviour of filter LFO

396        - added support for velocity effect on amplifier envelope time
397          (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
398          ampeg_vel2release)
399        - added support for EG hold (ampeg_hold)
400        - added support for sample offset (offset)
401        - use the newly introduced signal units model
402        - implemented opcodes lfoN_delay,

736          instrument was completely reloaded again.
737        - fixed handling of rapid bank select and program change messages
738          sent to the same sampler channel (patch from the Open Octave
739          project, slightly adjusted)
740        - fixed crash when trying to create an effect instance with controls
741          which min and/or max values depend on the sample rate
742        - fixed bug #162
743        - bugfix: LADSPA_PATH was not evaluated correctly when containing
744          multiple paths (#165)
745        - thread safety fixes for the instrument loading thread
746        - bugfix: instrument loading crashed for sfz and sf2 in Ardour

756          (labelled "Disk stream not available in time")
757        - Update effects on sample rate & period size changes (to avoid

762          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
763          practically irrelevant, however it caused problems with the new LSCP
764          shell's auto completion feature).
