# Line 1  Line 1 
1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3    * General changes:    * SFZ format engine:
4        - added support for <global>, <master> and #define (patch by Alby M)
5    
6      * general changes:
7        - fixed printf type errors (mostly in debug messages)
8        - use unique_ptr instead of auto_ptr when building with C++11
9        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
10          allowing to sort data efficiently in real-time safe manner.
11        - RTList class: added methods for moving/inserting elements to arbitrary
12          position within a list.
13        - RTList class: added method fromPtr() for creating an Iterator object from
14          a raw element pointer.
15        - Attempt to partly fix resetting engine channels vs. resetting engine, an
16          overall cleanup of the Reset*(), ConnectAudioDevice(),
17          DisconnectAudioDevice() API methods would still be desirable though,
18          because the current situation is still inconsistent and error prone.
19        - Active voices are now internally grouped to "Note" objects, instead of
20          being directly assigned to a keyboard key. This allows more fine graded
21          processing of voices, which is i.e. required for certain instrument
22          script features.
23        - Fix: Release trigger voices were not spawned on sustain pedal up
24          (CC #64) events.
25        - Fix: Release trigger voices can now also distinguish correctly between
26          note-off and sustain pedal up events.
27        - All engines: Increased ramp speed of volume smoother and pan smoother
28          (while slow rate of crossfade smoother is preserved) to allow quick
29          volume and pan changes by instrument scripts for instance.
30        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
31          properly and thus were ignored for certain uses.
32        - Added new C++ API method
33          VirtualMidiDevice::SendChannelPressureToSampler().
34    
35      * packaging changes:
36        - removed unnecessary dependency to libuuid
37          (originated by libgig's usage of it)
38        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
39          auto detect whether it (sh/c)ould output its messages in color.
40    
41      * Real-time instrument scripts:
42        - Implemented scheduler for delayed MIDI events and for suspended scripts.
43        - Built-in script function "wait()": implemented support for function's
44          "duration-us" argument, thus scripts using this function are now
45          correctly resumed after the requested amount of microseconds.
46        - Built-in script function "play_note()": implemented support for
47          function's "duration-us" argument, thus notes triggered with this
48          argument are now correctly released after the requested amount of
49          microseconds.
50        - Fix: script events were not cleared when engine channel was reset,
51          potentially causing undefined behavior.
52        - Fixed crash which happened when trying to reference an undeclared
53          variable.
54        - Built-in script function "play_note()": Added support for passing
55          special value -1 for "duration-us" argument, which will cause the
56          triggered note to be released once the original note was released.
57        - Instrument script classes now exported with the liblinuxsampler C++ API.
58        - Added new API method ScriptVM::syntaxHighlighting() which provides
59          a convenient syntax highlighting backend for external instrument
60          script editor applications.
61        - Added new C++ API class "ScriptVMFactory".
62        - Extended parser issues to provide not only first line and first
63          column, but also last line and last column of issue (thus marking
64          the precise span of the issue within the source code).
65        - Reload script automatically after being modified by an instrument
66          editor.
67        - NKSP language grammar correction: allow empty event handler bodies
68          like "on note end on".
69        - Implemented built-in script function "change_vol()".
70        - Implemented built-in script function "change_tune()".
71        - Implemented built-in script function "change_pan()".
72        - Implemented built-in script function "change_cutoff()".
73        - Implemented built-in script function "change_reso()".
74        - Implemented built-in script function "event_status()".
75        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
76          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
77          "event_status()" function.
78        - NKSP language: Added support for bitwise operators ".or.", ".and."
79          and ".not.".
80        - NKSP language scanner: Fixed IDs matching to require at least one
81          character (i.e. when matching function names or variable names).
82        - NKSP language scanner: disabled unusued rules.
83        - Fixed behavior of play_note() and note_off() functions which must
84          be distinguished engine internally from "real" MIDI note on/off
85          events in order to avoid misbehaviors like hanging notes.
86        - Implemented built-in script variable "$KSP_TIMER".
87        - Implemented built-in script variable "$NKSP_REAL_TIMER".
88        - Implemented built-in script variable "$NKSP_PERF_TIMER".
89        - Implemented built-in script variable "$ENGINE_UPTIME".
90        - Implemented built-in script function "inc()".
91        - Implemented built-in script function "dec()".
92        - NKSP language fix: division expressions were evaluated too often.
93        - NKSP language fix: string concatenation operator was right
94          associative instead of left (to right).
95        - NKSP language correction: allow empty statements in entire language
96          (i.e. "if end if").
97        - Implemented built-in script function "stop_wait()".
98        - Implemented built-in script variable "$NI_CALLBACK_ID".
99        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
100        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
101        - Added support for read-only built-in variables (respectively
102          handled by the script parser).
103        - Added built-in script constant "$NI_CB_TYPE_INIT".
104        - Added built-in script constant "$NI_CB_TYPE_NOTE".
105        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
106        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
107        - NKSP Language: Added support for user defined script functions.
108        - Implemented built-in script function "change_attack()".
109        - Implemented built-in script function "change_decay()".
110        - Implemented built-in script function "change_release()".
111        - Fixed all change_*() built-in script functions to apply their
112          synthesis parameter changes immediately in case the respective note
113          was triggered at the same time, instead of scheduling the parameter
114          change, especially because it would cause some parameter types's
115          changes either to be ramped (i.e. change_vol()) or other types even
116          to have not effect at all (i.e. change_attack()).
117        - Implemented built-in script function "sh_left()".
118        - Implemented built-in script function "sh_right()".
119        - Implemented built-in script function "min()".
120        - Implemented built-in script function "max()".
121        - NKSP Fix: "init" event handler was not always executed when a script
122          was loaded.
123        - NKSP built-in wait() script function: abort script execution if
124          a negative or zero wait time was passed as argument (since this is
125          a common indication of a bug either of the script or even of the
126          engine, which could lead to RT instability or even worse).
127        - ScriptVM: Implemented automatic suspension of RT safety
128          threatening scripts.
129        - Provide more user friendly error messages on syntax errors.
130        - Fixed NKSP parser warning "Not a statement" when assigning an
131          initializer list to an array variable.
132

181        (patch by Luis Garrido, slightly modified).        (patch by Luis Garrido, slightly modified).
182        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
183        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
184        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
185          note (in this implementation of the sampler its simply hard routed to
186          the 1st effect send of the sampler channel, no matter what the actual
187          effect type is)
188        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
189          note (in this implementation of the sampler its simply hard routed to
190          the 2nd effect send of the sampler channel, no matter what the actual
191          effect type is)
192        - implemented support for internal LADSPA effects
193        - raised limit of program change queue from 100 to 512
194          (as suggested by Alex Stone)
195        - implemented sine LFO, pulse LFO and saw LFO
196        - experimental support for per voice equalization
197        - added command line option --exec-after-init
198        - Introduced new C++ API method:
199          EngineChannel::InstrumentFileName(int index)
200          allowing to retrieve the whole list of files used for the loaded
201          instrument on an engine channel (a.k.a. part). Some GigaStudio
202          instruments for example are splitted over several files like
203          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
204        - Added new C++ API method Sampler::GetGlobalMaxVoices().
205        - Added new C++ API method Sampler::GetGlobalMaxStreams().
206        - Added new C++ API method Sampler::SetGlobalMaxVoices().
207        - Added new C++ API method Sampler::SetGlobalMaxStreams().
208        - Various "const" and "restrict" optimizations.
209        - all engines: add pan CC value to instrument pan parameter before
210          applying panning, instead of using two separate pan functions in
211          series (#182)
212        - added a lock guard class for exception safe mutex handling and
213          used it everywhere appropriate
214        - Immediately apply scale tuning changes to active voices.
215        - Exposed scale tuning to C++ API (along to the already existing standard
216          SysEx way).
217        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
218          and broken for ppc64. (Seq_cst loads and stores are actually not
219          used in LS, so the bug wasn't noticable.)
220        - lsatomic.h: added ARMv7 support
221        - Added support for multiple MIDI input ports per sampler channel (and
222          added various new C++ methods for this new feature / design change, old
223          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
224          as deprecated but are still there and should provide full behavior
225          backward compatibility).
226        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
227          unsafe and caused compilation error with clang 2.x).
228        - Bugfix: only process the latest MIDI program change event.
229        - Introducing the LSCP shell, which provides convenient control of the
230          sampler from the command line by providing LSCP aware features.
231        - VirtualMidiDevice: Added support for program change.
232        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
233        - VirtualMidiDevice: Added support for pitch bend.
234        - Aftertouch: extended API to explicitly handle channel pressure and
235          polyphonic key pressure events (so far polyphonic pressure was not
236          supported at all, and channel pressure was rerouted as CC128 but not
237          used so far).
238        - Added initial support for real-time instrument scripts. The script VM
239          code is shared by all sampler engine implemementations, however only the
240          gig file format currently provides support for storing instrument scripts
241          (as LinuxSampler extension to the original GigaStudio 4 format).
242    
243    * Gigasampler format engine:    * Gigasampler format engine:

249        - bugfix: pitch LFO controller "internal+aftertouch" was broken
250        - bugfix: filter keyboard tracking was broken
251        - filter performance fix (an unnecessary copy was made of the
252          filter parameters in each sub fragment)
253        - handle special case when pan parameter in gig file has max or
254          min value
255        - Exclusive Groups: don't ever stop voices of the same note,
256          doesn't sound naturally with a drumkit
257        - fixed EG1 modulation when attack or release is zero
258        - Fixed support for 'aftertouch' attenuation controller.
259        - Fixed crash that happened with velocity split sounds under certain
260          conditions (see also previous commit on libgig).
261        - fixed behaviour of filter LFO

288        - fixed a bug that could cause voice stealing to fail
289        - optimized sample lookup
290        - improved support for exclusive groups (group, off_by and
291          off_mode)

637          after MIDI/audio device creation failure
638        - When creating MIDI instrument map entries with "PERSISTENT" type, the
639          instruments were uselessly precached with zero samples, however it still
640          took the full preloading time and on 1st program change the respective
641          instrument was completely reloaded again.
642        - fixed handling of rapid bank select and program change messages
643          sent to the same sampler channel (patch from the Open Octave

664        - ignore missing LADSPA paths without ignoring valid LADSPA paths
665          (fixes #208)
666        - Fixed bug in LSCP grammar definition which caused a statement like
667          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
668          practically irrelevant, however it caused problems with the new LSCP
669          shell's auto completion feature).
670        - Fixed MIDI program change messages being ignored if quickly executed
671          after each other (fixes #231).
