# Line 1  Line 1 
1  Version CVS HEAD (?)  Version 2.1.0 (25 Nov 2017)
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".

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        - Added built-in script function "change_cutoff_attack()".
258        - Added built-in script function "change_cutoff_decay()".
259        - Added built-in script function "change_cutoff_sustain()".
260        - Added built-in script function "change_cutoff_release()".
261        - Added built-in script function "change_cutoff_lfo_depth()".
262        - Added built-in script function "change_cutoff_lfo_freq()".
263    
264      * Instruments DB:
265        - Fixed memory access bug of general DB access code which lead to
266          undefined behavior.
267        - Cleanup of instruments DB file creation and opening code.
268        - The instrument DB path of linuxsampler's --create-instruments-db argument
269          is now optional, if it is missing, then a default location is used.
270        - Added support for scanning SFZ (.sfz) files.
271        - Added support for scanning Sound Font (.sf2) files.
272        - Fixed undefined DB transaction behavior.

349      - Various "const" and "restrict" optimizations.      - Various "const" and "restrict" optimizations.
350        - all engines: add pan CC value to instrument pan parameter before
351          applying panning, instead of using two separate pan functions in
352          series (#182)
353        - added a lock guard class for exception safe mutex handling and
354          used it everywhere appropriate
355        - Immediately apply scale tuning changes to active voices.
356        - Exposed scale tuning to C++ API (along to the already existing standard
357          SysEx way).
358        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
359          and broken for ppc64. (Seq_cst loads and stores are actually not
360          used in LS, so the bug wasn't noticable.)
361        - lsatomic.h: added ARMv7 support
362        - Added support for multiple MIDI input ports per sampler channel (and
363          added various new C++ methods for this new feature / design change, old
364          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
365          as deprecated but are still there and should provide full behavior
366          backward compatibility).
367        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
368          unsafe and caused compilation error with clang 2.x).
369        - Bugfix: only process the latest MIDI program change event.
370        - Introducing the LSCP shell, which provides convenient control of the
371          sampler from the command line by providing LSCP aware features.
372        - VirtualMidiDevice: Added support for program change.
373        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
374        - VirtualMidiDevice: Added support for pitch bend.
375        - Aftertouch: extended API to explicitly handle channel pressure and
376          polyphonic key pressure events (so far polyphonic pressure was not
377          supported at all, and channel pressure was rerouted as CC128 but not
378          used so far).
379        - Added initial support for real-time instrument scripts. The script VM
380          code is shared by all sampler engine implemementations, however only the
381          gig file format currently provides support for storing instrument scripts
382          (as LinuxSampler extension to the original GigaStudio 4 format).

392        - filter performance fix (an unnecessary copy was made of the
393          filter parameters in each sub fragment)
394        - handle special case when pan parameter in gig file has max or
395          min value
396        - Exclusive Groups: don't ever stop voices of the same note,
397          doesn't sound naturally with a drumkit
398        - fixed EG1 modulation when attack or release is zero
399        - Fixed support for 'aftertouch' attenuation controller.
400        - Fixed crash that happened with velocity split sounds under certain
401          conditions (see also previous commit on libgig).
