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        - 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    
28      * Real-time instrument scripts:
29        - Implemented scheduler for delayed MIDI events and for suspended scripts.
30        - Built-in script function "wait()": implemented support for function's
31          "duration-us" argument, thus scripts using this function are now
32          correctly resumed after the requested amount of microseconds.
33        - Built-in script function "play_note()": implemented support for
34          function's "duration-us" argument, thus notes triggered with this
35          argument are now correctly released after the requested amount of
36          microseconds.
37        - Fix: script events were not cleared when engine channel was reset,
38          potentially causing undefined behavior.
39        - Fixed crash which happened when trying to reference an undeclared
40          variable.
41        - Built-in script function "play_note()": Added support for passing
42          special value -1 for "duration-us" argument, which will cause the
43          triggered note to be released once the original note was released.
44    
45    Version 2.0.0 (15 July 2015)

80        - support building with spaces in vst sdk path
81        - enabled automake 'subdir-objects' option and moved external
82          source references (vst, au, asio) from makefiles to cpp files,
83          in order to get rid of warnings from automake 1.14

132      - lsatomic.h: added ARMv7 support      - lsatomic.h: added ARMv7 support
133        - Added support for multiple MIDI input ports per sampler channel (and
134          added various new C++ methods for this new feature / design change, old
135          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
136          as deprecated but are still there and should provide full behavior
137          backward compatibility).
138        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
139          unsafe and caused compilation error with clang 2.x).
140        - Bugfix: only process the latest MIDI program change event.
141        - Introducing the LSCP shell, which provides convenient control of the
142          sampler from the command line by providing LSCP aware features.
143        - VirtualMidiDevice: Added support for program change.
144        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
145        - VirtualMidiDevice: Added support for pitch bend.
146        - Aftertouch: extended API to explicitly handle channel pressure and
147          polyphonic key pressure events (so far polyphonic pressure was not
148          supported at all, and channel pressure was rerouted as CC128 but not
149          used so far).
150        - Added initial support for real-time instrument scripts. The script VM
151          code is shared by all sampler engine implemementations, however only the
152          gig file format currently provides support for storing instrument scripts
153          (as LinuxSampler extension to the original GigaStudio 4 format).

388          informations like the EngineChannel for which the instrument editor was
389          spawned for. This allows the instrument editors to interact more actively
390          with the sampler.

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

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