# 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    
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".

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()".
150        - Implemented built-in script function "change_amp_lfo_freq()".
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.

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.

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
