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    
66    Version 2.0.0 (15 July 2015)

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

184        - filter performance fix (an unnecessary copy was made of the
185          filter parameters in each sub fragment)
186        - handle special case when pan parameter in gig file has max or
187          min value
188        - Exclusive Groups: don't ever stop voices of the same note,
189          doesn't sound naturally with a drumkit
190        - fixed EG1 modulation when attack or release is zero
191        - Fixed support for 'aftertouch' attenuation controller.
192        - Fixed crash that happened with velocity split sounds under certain

409          informations like the EngineChannel for which the instrument editor was
410          spawned for. This allows the instrument editors to interact more actively
411          with the sampler.

571        - When creating MIDI instrument map entries with "PERSISTENT" type, the
572          instruments were uselessly precached with zero samples, however it still
573          took the full preloading time and on 1st program change the respective
574          instrument was completely reloaded again.
575        - fixed handling of rapid bank select and program change messages
576          sent to the same sampler channel (patch from the Open Octave
577          project, slightly adjusted)

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