# 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    
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    
20      * packaging changes:
21        - removed unnecessary dependency to libuuid
22          (originated by libgig's usage of it)
23    
24      * Real-time instrument scripts:
25        - Implemented scheduler for delayed MIDI events and for suspended scripts.
26        - Built-in script function "wait()": implemented support for function's
27          "duration-us" argument, thus scripts using this function are now
28          correctly resumed after the requested amount of microseconds.
29        - Built-in script function "play_note()": implemented support for
30          function's "duration-us" argument, thus notes triggered with this
31          argument are now correctly released after the requested amount of
32          microseconds.
33        - Fix: script events were not cleared when engine channel was reset,
34          potentially causing undefined behavior.
35        - Fixed crash which happened when trying to reference an undeclared
36          variable.
37    
38    Version 2.0.0 (15 July 2015)

67          makefiles
68        - fix for building with bison 3.0 (#202)
69        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
70          on the process's main thread
71        - fixed build error on newer MinGW
72        - support building with older jack versions
73        - support building with spaces in vst sdk path
74        - enabled automake 'subdir-objects' option and moved external
75          source references (vst, au, asio) from makefiles to cpp files,
76          in order to get rid of warnings from automake 1.14

116        series (#182)        series (#182)
117        - added a lock guard class for exception safe mutex handling and
118          used it everywhere appropriate
119        - Immediately apply scale tuning changes to active voices.
120        - Exposed scale tuning to C++ API (along to the already existing standard
121          SysEx way).
122        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
123          and broken for ppc64. (Seq_cst loads and stores are actually not
124          used in LS, so the bug wasn't noticable.)
125        - lsatomic.h: added ARMv7 support
126        - Added support for multiple MIDI input ports per sampler channel (and
127          added various new C++ methods for this new feature / design change, old
128          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
129          as deprecated but are still there and should provide full behavior
130          backward compatibility).
131        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
132          unsafe and caused compilation error with clang 2.x).
133        - Bugfix: only process the latest MIDI program change event.
134        - Introducing the LSCP shell, which provides convenient control of the
135          sampler from the command line by providing LSCP aware features.
136        - VirtualMidiDevice: Added support for program change.
137        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
138        - VirtualMidiDevice: Added support for pitch bend.
139        - Aftertouch: extended API to explicitly handle channel pressure and
140          polyphonic key pressure events (so far polyphonic pressure was not
141          supported at all, and channel pressure was rerouted as CC128 but not
142          used so far).
143        - Added initial support for real-time instrument scripts. The script VM
144          code is shared by all sampler engine implemementations, however only the
145          gig file format currently provides support for storing instrument scripts
146          (as LinuxSampler extension to the original GigaStudio 4 format).

379      * Instrument editor interface:
380        - Changed instrument editor plugin interface, providing additional
381          informations like the EngineChannel for which the instrument editor was
382          spawned for. This allows the instrument editors to interact more actively
383          with the sampler.

459        - provide comprehensive error messages on LSCP syntax errors
460          (suggesting expected next non-terminal symbols)

462      * LSCP shell:
463        - Added support for auto correction of obvious and trivial syntax mistakes.
464        - Added support for auto completion by tab key.

469          be the case in other shells).
470        - Added support for moving cursor left/right with arrow keys.
471        - Added support for built-in LSCP reference documentation, which will
472          automatically show the relevant LSCP reference section on screen as soon

521          (i.e. return value of new script function "by_marks()").
522        - Pass/preserve polyphonic variable data from respective "note" event
523          handler to "release" event handler.

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