# 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)

77    
78    * general changes:    * general changes:
79      - Refactoring: moved the independent code from      - Refactoring: moved the independent code from
# Line 25  Version CVS HEAD (?) Line 97  Version CVS HEAD (?)
97      - implemented support for internal LADSPA effects      - implemented support for internal LADSPA effects
98      - raised limit of program change queue from 100 to 512      - raised limit of program change queue from 100 to 512
99        (as suggested by Alex Stone)        (as suggested by Alex Stone)
100        - implemented sine LFO, pulse LFO and saw LFO
101        - experimental support for per voice equalization
102        - added command line option --exec-after-init
103        - Introduced new C++ API method:
104          EngineChannel::InstrumentFileName(int index)
105          allowing to retrieve the whole list of files used for the loaded
106          instrument on an engine channel (a.k.a. part). Some GigaStudio
107          instruments for example are splitted over several files like
108          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
109        - Added new C++ API method Sampler::GetGlobalMaxVoices().
110        - Added new C++ API method Sampler::GetGlobalMaxStreams().
111        - Added new C++ API method Sampler::SetGlobalMaxVoices().
112        - Added new C++ API method Sampler::SetGlobalMaxStreams().
113        - Various "const" and "restrict" optimizations.
114        - all engines: add pan CC value to instrument pan parameter before
115          applying panning, instead of using two separate pan functions in
116          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).
147    
148    * Gigasampler format engine:    * Gigasampler format engine:

158        - handle special case when pan parameter in gig file has max or
159          min value
160        - Exclusive Groups: don't ever stop voices of the same note,

404        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
405        - MME bugfix: driver wasn't closed properly
406        - CoreMIDI: automatically connect to all input sources by default (driver
407          parameter "AUTO_BIND").

542          after MIDI/audio device creation failure
543        - When creating MIDI instrument map entries with "PERSISTENT" type, the
544          instruments were uselessly precached with zero samples, however it still
545          took the full preloading time and on 1st program change the respective
546          instrument was completely reloaded again.
547        - fixed handling of rapid bank select and program change messages

566          (labelled "Disk stream not available in time")
567        - Update effects on sample rate & period size changes (to avoid
568          crashes and noise on such transitions).
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).
