# 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    
67      * Real-time instrument scripts:
68        - Implemented scheduler for delayed MIDI events and for suspended scripts.
69        - Built-in script function "wait()": implemented support for function's
70          "duration-us" argument, thus scripts using this function are now
71          correctly resumed after the requested amount of microseconds.
72        - Built-in script function "play_note()": implemented support for
73          function's "duration-us" argument, thus notes triggered with this
74          argument are now correctly released after the requested amount of
75          microseconds.
76        - Fix: script events were not cleared when engine channel was reset,
77          potentially causing undefined behavior.
78        - Fixed crash which happened when trying to reference an undeclared
79          variable.
80        - Built-in script function "play_note()": Added support for passing
81          special value -1 for "duration-us" argument, which will cause the
82          triggered note to be released once the original note was released.
83        - Instrument script classes now exported with the liblinuxsampler C++ API.
84        - Added new API method ScriptVM::syntaxHighlighting() which provides
85          a convenient syntax highlighting backend for external instrument
86          script editor applications.
87        - Added new C++ API class "ScriptVMFactory".
88        - Extended parser issues to provide not only first line and first
89          column, but also last line and last column of issue (thus marking
90          the precise span of the issue within the source code).
91        - Reload script automatically after being modified by an instrument
92          editor.
93        - NKSP language grammar correction: allow empty event handler bodies
94          like "on note end on".
95        - Implemented built-in script function "change_vol()".
96        - Implemented built-in script function "change_tune()".
97        - Implemented built-in script function "change_pan()".
98        - Implemented built-in script function "change_cutoff()".
99        - Implemented built-in script function "change_reso()".
100        - Implemented built-in script function "event_status()".
101        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
102          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
103          "event_status()" function.
104        - NKSP language: Added support for bitwise operators ".or.", ".and."
105          and ".not.".
106        - NKSP language scanner: Fixed IDs matching to require at least one
107          character (i.e. when matching function names or variable names).
108        - NKSP language scanner: disabled unusued rules.
109        - Fixed behavior of play_note() and note_off() functions which must
110          be distinguished engine internally from "real" MIDI note on/off
111          events in order to avoid misbehaviors like hanging notes.
112        - Implemented built-in script variable "$KSP_TIMER".
113        - Implemented built-in script variable "$NKSP_REAL_TIMER".
114        - Implemented built-in script variable "$NKSP_PERF_TIMER".
115        - Implemented built-in script variable "$ENGINE_UPTIME".
116        - Implemented built-in script function "inc()".
117        - Implemented built-in script function "dec()".
118        - NKSP language fix: division expressions were evaluated too often.
119        - NKSP language fix: string concatenation operator was right
120          associative instead of left (to right).
121        - NKSP language correction: allow empty statements in entire language
122          (i.e. "if end if").
123        - Implemented built-in script function "stop_wait()".
124        - Implemented built-in script variable "$NI_CALLBACK_ID".
125        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
126        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
127        - Added support for read-only built-in variables (respectively
128          handled by the script parser).
129        - Added built-in script constant "$NI_CB_TYPE_INIT".
130        - Added built-in script constant "$NI_CB_TYPE_NOTE".
131        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
132        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".

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

162        - Implemented built-in script function "change_pitch_lfo_depth()".
163        - Implemented built-in script function "change_pitch_lfo_freq()".
164        - Implemented built-in script function "change_vol_time()".
165        - Implemented built-in script function "change_tune_time()".
166        - Implemented built-in script function "fade_in()".
167        - Implemented built-in script function "fade_out()".
168        - Fixed acceptance of wrong data type of parameters passed to built-in
169          script functions "change_vol()", "change_tune()", "change_pan()",
170          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
171          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
172          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
173        - Added built-in script function "get_event_par()" and implemented some
174          of its possible parameter selections.
175        - Added built-in script function "set_event_par()" and implemented some
176          of its possible parameter selections.
177        - Fixed a bunch of scheduler time related bugs.
178        - Fixed polyphonic variables not being reset to zero after usage.
179        - Built-in "ignore_event()" function: argument is now optional, like with
180          built-in function "ignore_controller()".
181        - Implemented built-in script function "change_velo()".
182        - Implemented built-in script function "change_note()".
183        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
184          intuitive behavior if used in combination with "change_vol_time()" or
185          "change_tune_time()" respectively: now tuning/volume changes are only
186          assigned (without delay) immediately to a new note if the respective
187          timing function has not been called before, otherwise the volume/tuning
188          changes are automatically faded (before, only the event's time stamp was
189          relevant).
190         - Implemented built-in script function "array_equal()".
191         - Implemented built-in script function "search()".
192         - Implemented built-in script function "sort()".
193         - NKSP Fix: Never suspend "init" event handlers.
194         - Implemented built-in script function "same_region()" (currently only
195           available for gig format engine).
196         - Added built-in script constant "$NKSP_LINEAR".
197         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
198         - Implemented built-in script function "change_vol_curve()".
199         - Implemented built-in script function "change_tune_curve()".
200         - built-in "play_note()" function now supports a sample playback start
201           offset with argument 3, where special value -1 means to use the regular
202           sample offset as defined by the instrument file.
203         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
204         - Built-in variable $EVENT_NOTE is now a read-only variable.
205         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
206         - built-in "play_note()" function now accepts -2 for its fourth argument
207           (note duration) which means the life time of the note shall be sticked
208           to the requested note number of argument 1.
209         - Fix: built-in "play_note()" function now returns 0 as result value if
210           -1 was passed for its fourth argument (note duration) and the respective
211           parent note is already gone.
212        - Implemented built-in script function "change_play_pos()".
213        - NKSP language: Added support for user declared const array variables.

220          another script handler by passing its callback ID.
221        - Fixed potential memory access bug and potential undefined behavior of
222          "init" event handlers.
223        - Print a time stamp along to each call of built-in function "message()".
224        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
225          to retrieve all code blocks filtered out by the preprocessor.
226        - Added built-in script function "fork()".
227        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
228        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
229        - Fixed potential crash when accessing dynamic built-in array variables.
230        - Added built-in script function "callback_status()".
231        - Added built-in constant $CALLBACK_STATUS_TERMINATED.
232        - Added built-in constant $CALLBACK_STATUS_QUEUE.
233        - Added built-in constant $CALLBACK_STATUS_RUNNING.
234        - Removed max. value limitation of built-in functions "change_attack()",
235          "change_decay()" and "change_release()" to i.e. allow passing 2000000
236          for doubling the respective time.
237        - NKSP script editor syntax highlighting API: Fixed app termination due
238          to a lexer start condition stack underrun.
239        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
240          USE_CODE_IF_NOT() preprocessor statements.
241        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
242          can be set to disable all subsequent built-in "message()" function calls
243          on preprocessor level.
244        - Implemented built-in script function "change_sustain()".
245        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
246          to avoid the editor app to crash on ill-formed text input.
247    
248      * Instruments DB:
249        - Fixed memory access bug of general DB access code which lead to
250          undefined behavior.
251        - Cleanup of instruments DB file creation and opening code.
252        - The instrument DB path of linuxsampler's --create-instruments-db argument
253          is now optional, if it is missing, then a default location is used.
254        - Added support for scanning SFZ (.sfz) files.
255        - Added support for scanning Sound Font (.sf2) files.
256        - Fixed undefined DB transaction behavior.
