# Line 1  Line 1 
1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3    * plugin changes:    * SFZ format engine:
4      - LV2 Persist + Files support (patch by David Robillard)      - 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    
28      * packaging changes:
29        - removed unnecessary dependency to libuuid
30          (originated by libgig's usage of it)
31        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
32          auto detect whether it (sh/c)ould output its messages in color.
33    
34      * Real-time instrument scripts:
35        - Implemented scheduler for delayed MIDI events and for suspended scripts.
36        - Built-in script function "wait()": implemented support for function's
37          "duration-us" argument, thus scripts using this function are now
38          correctly resumed after the requested amount of microseconds.
39        - Built-in script function "play_note()": implemented support for
40          function's "duration-us" argument, thus notes triggered with this
41          argument are now correctly released after the requested amount of
42          microseconds.
43        - Fix: script events were not cleared when engine channel was reset,
44          potentially causing undefined behavior.
45        - Fixed crash which happened when trying to reference an undeclared
46          variable.
47        - Built-in script function "play_note()": Added support for passing
48          special value -1 for "duration-us" argument, which will cause the
49          triggered note to be released once the original note was released.
50        - Instrument script classes now exported with the liblinuxsampler C++ API.
51        - Added new API method ScriptVM::syntaxHighlighting() which provides
52          a convenient syntax highlighting backend for external instrument
53          script editor applications.
54        - Added new C++ API class "ScriptVMFactory".
55        - Extended parser issues to provide not only first line and first
56          column, but also last line and last column of issue (thus marking
57          the precise span of the issue within the source code).
58        - Reload script automatically after being modified by an instrument
59          editor.
60        - NKSP language grammar correction: allow empty event handler bodies
61          like "on note end on".
62        - Implemented built-in script function "change_vol()".
63        - Implemented built-in script function "change_tune()".
64        - Implemented built-in script function "change_pan()".
65        - Implemented built-in script function "change_cutoff()".
66        - Implemented built-in script function "change_reso()".
67        - Implemented built-in script function "event_status()".
68        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
69          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
70          "event_status()" function.
71        - NKSP language: Added support for bitwise operators ".or.", ".and."
72          and ".not.".
73        - NKSP language scanner: Fixed IDs matching to require at least one
74          character (i.e. when matching function names or variable names).
75        - NKSP language scanner: disabled unusued rules.
76        - Fixed behavior of play_note() and note_off() functions which must
77          be distinguished engine internally from "real" MIDI note on/off
78          events in order to avoid misbehaviors like hanging notes.
79        - Implemented built-in script variable "$KSP_TIMER".
80        - Implemented built-in script variable "$NKSP_REAL_TIMER".
81        - Implemented built-in script variable "$NKSP_PERF_TIMER".
82        - Implemented built-in script variable "$ENGINE_UPTIME".
83

143      - implemented support for internal LADSPA effects      - implemented support for internal LADSPA effects
144      - raised limit of program change queue from 100 to 512      - raised limit of program change queue from 100 to 512
145        (as suggested by Alex Stone)        (as suggested by Alex Stone)
146        - implemented sine LFO, pulse LFO and saw LFO
147        - experimental support for per voice equalization
148        - added command line option --exec-after-init
149        - Introduced new C++ API method:
150          EngineChannel::InstrumentFileName(int index)
151          allowing to retrieve the whole list of files used for the loaded
152          instrument on an engine channel (a.k.a. part). Some GigaStudio
153          instruments for example are splitted over several files like
154          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
155        - Added new C++ API method Sampler::GetGlobalMaxVoices().
156        - Added new C++ API method Sampler::GetGlobalMaxStreams().
157        - Added new C++ API method Sampler::SetGlobalMaxVoices().
158        - Added new C++ API method Sampler::SetGlobalMaxStreams().
159        - Various "const" and "restrict" optimizations.
160        - all engines: add pan CC value to instrument pan parameter before
161          applying panning, instead of using two separate pan functions in
162          series (#182)
163        - added a lock guard class for exception safe mutex handling and
164          used it everywhere appropriate
165        - Immediately apply scale tuning changes to active voices.
166        - Exposed scale tuning to C++ API (along to the already existing standard
167          SysEx way).
168        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
169          and broken for ppc64. (Seq_cst loads and stores are actually not
170          used in LS, so the bug wasn't noticable.)
171        - lsatomic.h: added ARMv7 support
172        - Added support for multiple MIDI input ports per sampler channel (and
173          added various new C++ methods for this new feature / design change, old
174          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
175          as deprecated but are still there and should provide full behavior
176          backward compatibility).
177        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
178          unsafe and caused compilation error with clang 2.x).
179        - Bugfix: only process the latest MIDI program change event.
180        - Introducing the LSCP shell, which provides convenient control of the
181          sampler from the command line by providing LSCP aware features.
182        - VirtualMidiDevice: Added support for program change.
183        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
184        - VirtualMidiDevice: Added support for pitch bend.
185        - Aftertouch: extended API to explicitly handle channel pressure and
186          polyphonic key pressure events (so far polyphonic pressure was not
187          supported at all, and channel pressure was rerouted as CC128 but not
188          used so far).
189        - Added initial support for real-time instrument scripts. The script VM
190          code is shared by all sampler engine implemementations, however only the
191          gig file format currently provides support for storing instrument scripts
192          (as LinuxSampler extension to the original GigaStudio 4 format).
193    
194    * Gigasampler format engine:    * Gigasampler format engine:
195      - implemented the "round robin keyboard" dimension      - implemented the "round robin keyboard" dimension

200        - bugfix: pitch LFO controller "internal+aftertouch" was broken
201        - bugfix: filter keyboard tracking was broken
202        - filter performance fix (an unnecessary copy was made of the
203          filter parameters in each sub fragment)
204        - handle special case when pan parameter in gig file has max or
205          min value
206        - Exclusive Groups: don't ever stop voices of the same note,
207          doesn't sound naturally with a drumkit
208        - fixed EG1 modulation when attack or release is zero
209        - Fixed support for 'aftertouch' attenuation controller.
210        - Fixed crash that happened with velocity split sounds under certain
211          conditions (see also previous commit on libgig).
