# 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        - 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    
47    Version 2.0.0 (15 July 2015)

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).

479        - Added support for moving cursor left/right with arrow keys.
480        - Added support for built-in LSCP reference documentation, which will

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).
