# Line 1  Line 1 
1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3    * plugin changes:    * SFZ format engine:
4      - LV2 "state" extension 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

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

438          the driver will automatically connect to other CoreMIDI clients' ports
439          (e.g. external MIDI devices being attached to the Mac)
440        - added support for MIDI note on velocity filter
441        - CoreMIDI: fixed memory deallocation error

512        - Added support for moving cursor left/right with arrow keys.
513        - Added support for built-in LSCP reference documentation, which will
514          automatically show the relevant LSCP reference section on screen as soon
