# 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    
24      * packaging changes:
25        - removed unnecessary dependency to libuuid
26          (originated by libgig's usage of it)
27        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
28          auto detect whether it (sh/c)ould output its messages in color.
29    
30      * Real-time instrument scripts:
31        - Implemented scheduler for delayed MIDI events and for suspended scripts.
32        - Built-in script function "wait()": implemented support for function's
33          "duration-us" argument, thus scripts using this function are now
34          correctly resumed after the requested amount of microseconds.
35        - Built-in script function "play_note()": implemented support for
36          function's "duration-us" argument, thus notes triggered with this
37          argument are now correctly released after the requested amount of
38          microseconds.
39        - Fix: script events were not cleared when engine channel was reset,
40          potentially causing undefined behavior.
41        - Fixed crash which happened when trying to reference an undeclared
42          variable.
43        - Built-in script function "play_note()": Added support for passing
44          special value -1 for "duration-us" argument, which will cause the
45          triggered note to be released once the original note was released.
46

80        - fixed build error on newer MinGW
81        - support building with older jack versions
82        - support building with spaces in vst sdk path

117        "Foo.gig", "Foo.gx01", "Foo.gx02", ...        "Foo.gig", "Foo.gx01", "Foo.gx02", ...
118        - Added new C++ API method Sampler::GetGlobalMaxVoices().
119        - Added new C++ API method Sampler::GetGlobalMaxStreams().
120        - Added new C++ API method Sampler::SetGlobalMaxVoices().
121        - Added new C++ API method Sampler::SetGlobalMaxStreams().
122        - Various "const" and "restrict" optimizations.
123        - all engines: add pan CC value to instrument pan parameter before
124          applying panning, instead of using two separate pan functions in
125          series (#182)
126        - added a lock guard class for exception safe mutex handling and
127          used it everywhere appropriate
128        - Immediately apply scale tuning changes to active voices.
129        - Exposed scale tuning to C++ API (along to the already existing standard
130          SysEx way).
131        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
132          and broken for ppc64. (Seq_cst loads and stores are actually not
133          used in LS, so the bug wasn't noticable.)
134        - lsatomic.h: added ARMv7 support
135        - Added support for multiple MIDI input ports per sampler channel (and
136          added various new C++ methods for this new feature / design change, old
137          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
138          as deprecated but are still there and should provide full behavior
139          backward compatibility).
140        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
141          unsafe and caused compilation error with clang 2.x).
142        - Bugfix: only process the latest MIDI program change event.
143        - Introducing the LSCP shell, which provides convenient control of the
144          sampler from the command line by providing LSCP aware features.
145        - VirtualMidiDevice: Added support for program change.
146        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
147        - VirtualMidiDevice: Added support for pitch bend.
148        - Aftertouch: extended API to explicitly handle channel pressure and
149          polyphonic key pressure events (so far polyphonic pressure was not
150          supported at all, and channel pressure was rerouted as CC128 but not
151          used so far).
152        - Added initial support for real-time instrument scripts. The script VM
153          code is shared by all sampler engine implemementations, however only the
154          gig file format currently provides support for storing instrument scripts
155          (as LinuxSampler extension to the original GigaStudio 4 format).

336          (modified patch which was originally posted by Sergey on LS mailing list)
337        - bugfix: generation of velocity curves etc should not be done
338          after each "#include", only after the main file is parsed
339        - bugfix: line numbers in error messages were wrong after "#include"
340        - added support for float and 32 bit sample files

390          informations like the EngineChannel for which the instrument editor was

392          with the sampler.

415        - CoreMIDI: automatically connect to all input sources by default (driver
416          parameter "AUTO_BIND").

480        - Added support for built-in LSCP reference documentation, which will

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

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