# Line 1  Line 1 
1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3    * plugin changes:    * SFZ format engine:
4      - LV2 Persist + Files 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        - Instrument script classes now exported with the liblinuxsampler C++ API.
47        - Added new API method ScriptVM::syntaxHighlighting() which provides
48          a convenient syntax highlighting backend for external instrument
49          script editor applications.
50        - Added new C++ API class "ScriptVMFactory".
51        - Extended parser issues to provide not only first line and first
52          column, but also last line and last column of issue (thus marking
53          the precise span of the issue within the source code).
54    
55    Version 2.0.0 (15 July 2015)

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

175        - handle special case when pan parameter in gig file has max or
176          min value
177        - Exclusive Groups: don't ever stop voices of the same note,
178          doesn't sound naturally with a drumkit
179        - fixed EG1 modulation when attack or release is zero
180        - Fixed support for 'aftertouch' attenuation controller.

397        - Changed instrument editor plugin interface, providing additional
398          informations like the EngineChannel for which the instrument editor was
399          spawned for. This allows the instrument editors to interact more actively
400          with the sampler.

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

560        - When creating MIDI instrument map entries with "PERSISTENT" type, the
561          instruments were uselessly precached with zero samples, however it still
562          took the full preloading time and on 1st program change the respective
563          instrument was completely reloaded again.
564        - fixed handling of rapid bank select and program change messages
565          sent to the same sampler channel (patch from the Open Octave
566          project, slightly adjusted)

581          playing a note in a key group
582        - fixed erroneous error message piping in VoiceBase.h
583          (labelled "Disk stream not available in time")
584        - Update effects on sample rate & period size changes (to avoid
585          crashes and noise on such transitions).
586        - ignore missing LADSPA paths without ignoring valid LADSPA paths
587          (fixes #208)
588        - Fixed bug in LSCP grammar definition which caused a statement like
589          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
590          practically irrelevant, however it caused problems with the new LSCP
591          shell's auto completion feature).
592        - Fixed MIDI program change messages being ignored if quickly executed
593          after each other (fixes #231).
