# 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    
47      * packaging changes:
48        - removed unnecessary dependency to libuuid
49          (originated by libgig's usage of it)
50        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
51          auto detect whether it (sh/c)ould output its messages in color.
52    
53      * Real-time instrument scripts:
54        - Implemented scheduler for delayed MIDI events and for suspended scripts.
55        - Built-in script function "wait()": implemented support for function's
56          "duration-us" argument, thus scripts using this function are now
57          correctly resumed after the requested amount of microseconds.
58        - Built-in script function "play_note()": implemented support for
59          function's "duration-us" argument, thus notes triggered with this
60          argument are now correctly released after the requested amount of
61          microseconds.
62        - Fix: script events were not cleared when engine channel was reset,
63          potentially causing undefined behavior.
64        - Fixed crash which happened when trying to reference an undeclared
65          variable.
66        - Built-in script function "play_note()": Added support for passing
67          special value -1 for "duration-us" argument, which will cause the
68          triggered note to be released once the original note was released.
69        - Instrument script classes now exported with the liblinuxsampler C++ API.
70        - Added new API method ScriptVM::syntaxHighlighting() which provides
71          a convenient syntax highlighting backend for external instrument
72          script editor applications.
73        - Added new C++ API class "ScriptVMFactory".
74        - Extended parser issues to provide not only first line and first
75          column, but also last line and last column of issue (thus marking
76          the precise span of the issue within the source code).
77        - Reload script automatically after being modified by an instrument
78          editor.
79        - NKSP language grammar correction: allow empty event handler bodies
80          like "on note end on".
81        - Implemented built-in script function "change_vol()".
82        - Implemented built-in script function "change_tune()".
83        - Implemented built-in script function "change_pan()".
84        - Implemented built-in script function "change_cutoff()".
85        - Implemented built-in script function "change_reso()".
86        - Implemented built-in script function "event_status()".
87        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
88          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
89          "event_status()" function.
90        - NKSP language: Added support for bitwise operators ".or.", ".and."
91          and ".not.".
92        - NKSP language scanner: Fixed IDs matching to require at least one
93          character (i.e. when matching function names or variable names).
94        - NKSP language scanner: disabled unusued rules.
95        - Fixed behavior of play_note() and note_off() functions which must
96          be distinguished engine internally from "real" MIDI note on/off
97          events in order to avoid misbehaviors like hanging notes.
98        - Implemented built-in script variable "$KSP_TIMER".
99        - Implemented built-in script variable "$NKSP_REAL_TIMER".
100        - Implemented built-in script variable "$NKSP_PERF_TIMER".
101        - Implemented built-in script variable "$ENGINE_UPTIME".
102        - Implemented built-in script function "inc()".
103        - Implemented built-in script function "dec()".
104        - NKSP language fix: division expressions were evaluated too often.
105        - NKSP language fix: string concatenation operator was right
106          associative instead of left (to right).
107        - NKSP language correction: allow empty statements in entire language
108          (i.e. "if end if").
109        - Implemented built-in script function "stop_wait()".
110        - Implemented built-in script variable "$NI_CALLBACK_ID".
111        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
112        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
113        - Added support for read-only built-in variables (respectively
114          handled by the script parser).
115        - Added built-in script constant "$NI_CB_TYPE_INIT".
116        - Added built-in script constant "$NI_CB_TYPE_NOTE".
117        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
118        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
119        - NKSP Language: Added support for user defined script functions.
120        - Implemented built-in script function "change_attack()".
121        - Implemented built-in script function "change_decay()".
122        - Implemented built-in script function "change_release()".
123        - Fixed all change_*() built-in script functions to apply their
124          synthesis parameter changes immediately in case the respective note
125          was triggered at the same time, instead of scheduling the parameter
126          change, especially because it would cause some parameter types's
127          changes either to be ramped (i.e. change_vol()) or other types even
128          to have not effect at all (i.e. change_attack()).
129        - Implemented built-in script function "sh_left()".
130        - Implemented built-in script function "sh_right()".
131        - Implemented built-in script function "min()".
132        - Implemented built-in script function "max()".
133        - NKSP Fix: "init" event handler was not always executed when a script
134          was loaded.
135        - NKSP built-in wait() script function: abort script execution if
136          a negative or zero wait time was passed as argument (since this is
137          a common indication of a bug either of the script or even of the
138          engine, which could lead to RT instability or even worse).
139        - ScriptVM: Implemented automatic suspension of RT safety
140          threatening scripts.
141        - Provide more user friendly error messages on syntax errors.
142        - Fixed NKSP parser warning "Not a statement" when assigning an
143          initializer list to an array variable.
144        - Implemented built-in script array variable "%ALL_EVENTS".
145        - Implemented built-in script function "in_range()".
146        - Implemented built-in script function "change_amp_lfo_depth()".
147        - Implemented built-in script function "change_amp_lfo_freq()".
148        - Implemented built-in script function "change_pitch_lfo_depth()".
149        - Implemented built-in script function "change_pitch_lfo_freq()".
150        - Implemented built-in script function "change_vol_time()".
151        - Implemented built-in script function "change_tune_time()".
152        - Implemented built-in script function "fade_in()".
153        - Implemented built-in script function "fade_out()".
154        - Fixed acceptance of wrong data type of parameters passed to built-in
155          script functions "change_vol()", "change_tune()", "change_pan()",
156          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
157          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
158          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
159    
160      * Instruments DB:
161        - Fixed memory access bug of general DB access code which lead to
162          undefined behavior.
163        - Cleanup of instruments DB file creation and opening code.
164        - The instrument DB path of linuxsampler's --create-instruments-db argument
165          is now optional, if it is missing, then a default location is used.
166        - Added support for scanning SFZ (.sfz) files.
167        - Added support for scanning Sound Font (.sf2) files.
168        - Fixed undefined DB transaction behavior.

274          used so far).
275        - Added initial support for real-time instrument scripts. The script VM
276          code is shared by all sampler engine implemementations, however only the
