# 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        - 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    
51    Version 2.0.0 (15 July 2015)
52    
53      * packaging changes:
54        - fixed building with newer MinGW-w64
55        - Mac OS X: support the new dir for Core Audio SDK
56        - Mac OS X: fixed building outside source directory
57        - made sure all source files for hostplugins are included when
58          doing "make dist"
59        - removed empty directories left from the cvs to svn migration
60        - fixed compilation with gcc 4.6.1
61        - another "make dist" fix, for the LV2 plugin
62        - made --enable-pthread-testcancel default on Mac OS X
63        - minor Makefile fix for building lscpparser when build and source
64          directories are separate
65        - Mac OS X: made it possible to specify plugin installation dir to
66          configure
67        - Mac OS X: Makefile fix for the install-strip target
68        - fixed compilation with gcc 4.7
69        - fixed configure script error with old autoconf versions
70        - lsatomic.h: use gcc provided atomic functions if building with
71          gcc 4.7 and C++11
72        - modernized configure script
73        - fixed linkage error when building with
74          LDFLAGS="-Wl,--no-undefined" (#190)
75        - fixed compilation with Clang 3.2
76        - removed usage of deprecated Automake variable INCLUDES
77        - fixed building with C++11
78        - build fix: ChangeFlagRelaxed.h was missing in makefile
79        - build fix: libsndfile compiler flags were missing in some
80          makefiles
81        - fix for building with bison 3.0 (#202)
82        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
83          on the process's main thread
84        - fixed build error on newer MinGW
85        - support building with older jack versions
86        - support building with spaces in vst sdk path
87        - enabled automake 'subdir-objects' option and moved external
88          source references (vst, au, asio) from makefiles to cpp files,
89          in order to get rid of warnings from automake 1.14
90    
91      * general changes:
92        - Refactoring: moved the independent code from
93          the Gigasampler format engine to base classes
94        - command line option '--profile' is currently disabled, since the
95          respective profiling code is currently broken
96        - Introduced support for optional environment variable
97          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
98          where the sampler shall look for instrument editor plugins
99          (patch by Luis Garrido, slightly modified).
100        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
101        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
102        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
103          note (in this implementation of the sampler its simply hard routed to
104          the 1st effect send of the sampler channel, no matter what the actual
105          effect type is)
106        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
107          note (in this implementation of the sampler its simply hard routed to
108          the 2nd effect send of the sampler channel, no matter what the actual
109          effect type is)
110        - implemented support for internal LADSPA effects
111        - raised limit of program change queue from 100 to 512
112          (as suggested by Alex Stone)
113        - implemented sine LFO, pulse LFO and saw LFO
114        - experimental support for per voice equalization
115        - added command line option --exec-after-init
116        - Introduced new C++ API method:
117          EngineChannel::InstrumentFileName(int index)
118          allowing to retrieve the whole list of files used for the loaded
119          instrument on an engine channel (a.k.a. part). Some GigaStudio
120          instruments for example are splitted over several files like
121          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
122        - Added new C++ API method Sampler::GetGlobalMaxVoices().
123        - Added new C++ API method Sampler::GetGlobalMaxStreams().
124        - Added new C++ API method Sampler::SetGlobalMaxVoices().
125        - Added new C++ API method Sampler::SetGlobalMaxStreams().
126        - Various "const" and "restrict" optimizations.
127        - all engines: add pan CC value to instrument pan parameter before
128          applying panning, instead of using two separate pan functions in
129          series (#182)
130        - added a lock guard class for exception safe mutex handling and
131          used it everywhere appropriate
132        - Immediately apply scale tuning changes to active voices.
133        - Exposed scale tuning to C++ API (along to the already existing standard
134          SysEx way).
135        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
136          and broken for ppc64. (Seq_cst loads and stores are actually not
137          used in LS, so the bug wasn't noticable.)
138        - lsatomic.h: added ARMv7 support
139        - Added support for multiple MIDI input ports per sampler channel (and
140          added various new C++ methods for this new feature / design change, old
141          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
142          as deprecated but are still there and should provide full behavior
143          backward compatibility).
144        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
145          unsafe and caused compilation error with clang 2.x).
146        - Bugfix: only process the latest MIDI program change event.
147        - Introducing the LSCP shell, which provides convenient control of the
148          sampler from the command line by providing LSCP aware features.
149        - VirtualMidiDevice: Added support for program change.
150        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
151        - VirtualMidiDevice: Added support for pitch bend.
152        - Aftertouch: extended API to explicitly handle channel pressure and
153          polyphonic key pressure events (so far polyphonic pressure was not
154          supported at all, and channel pressure was rerouted as CC128 but not
155          used so far).
156        - Added initial support for real-time instrument scripts. The script VM
157          code is shared by all sampler engine implemementations, however only the
158          gig file format currently provides support for storing instrument scripts
159          (as LinuxSampler extension to the original GigaStudio 4 format).
160    
161      * Gigasampler format engine:
162        - implemented the "round robin keyboard" dimension
163        - fixed round robin and random dimensions for cases when number of
164          dimension zones is not a power of two
165        - made round robin use a counter for each region instead of each
166          key
167        - bugfix: pitch LFO controller "internal+aftertouch" was broken
168        - bugfix: filter keyboard tracking was broken
169        - filter performance fix (an unnecessary copy was made of the
170          filter parameters in each sub fragment)
171        - handle special case when pan parameter in gig file has max or
172          min value
173        - Exclusive Groups: don't ever stop voices of the same note,
174          doesn't sound naturally with a drumkit
175        - fixed EG1 modulation when attack or release is zero
176        - Fixed support for 'aftertouch' attenuation controller.
177        - Fixed crash that happened with velocity split sounds under certain
178          conditions (see also previous commit on libgig).

184        - added a fine-tuned v1 envelope generator instead of using the
185          one from the gig engine

198        - added support for amp_veltrack and amp_velcurve_N
199        - fine-tuned the default velocity curve
200        - added support for transpose
201        - fixed crash when using sw_down/up
202        - improved logic for sw_lokey/hikey/up/down/last
203        - added more v1 aliases to parser
204        - reduced memory usage for sfz data
205        - RT-safeness: avoid malloc in audio thread
206        - fixed a bug that could cause voice stealing to fail
207        - optimized sample lookup
208        - improved support for exclusive groups (group, off_by and

212        - fixed playback of 16 bit wav files on big endian CPUs
213        - added support for Ogg Vorbis sample files
214        - use loop markers from sample file if loop_start and loop_end are
215          not set in sfz file

340          (modified patch which was originally posted by Sergey on LS mailing list)
341        - bugfix: generation of velocity curves etc should not be done
342          after each "#include", only after the main file is parsed
343        - bugfix: line numbers in error messages were wrong after "#include"
344        - added support for float and 32 bit sample files
345    
346      * SoundFont format engine:
347        - Initial implementation (not usable yet)
348        - RT-safeness: avoid malloc in audio thread
349        - fixed a bug that could cause voice stealing to fail
350        - fine-tuned amplitude EG (by switching from gig to sfz EG)
351        - initial implementation of Vibrato LFO and Modulation LFO
352        - initial implementation of cutoff filter
353        - use linear decay and release for filter and pitch EG
354    
355      * Host plugins (VST, AU, LV2, DSSI):
356        - AU bugfix: failed to destroy its audio/MIDI devices
357        - Listen to all interfaces on Mac OS X (INADDR_ANY)
358        - VST bugfix: If the host called resume() before and after
359          changing sample rate or block size, the number of channels was
360          incorrectly set to two. This caused silence in Cubase 5.
361        - save engine type (gig, sfz or sf2) in plugin state
362        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
363          64 bit Windows
364        - AU: changed number of output channels from one stereo to 16
365          stereo
366        - VST: made it possible to build the VST plugin for Mac

373          loaded a second time (this time it's for Linux and Mac, previous
374          similar fix was for Windows)
375        - thread safety fixes for the instrument loading thread
376        - LV2: use the new lv2 package if present
377        - VST: try to open Fantasia automatically on Linux and Mac too (on
378          Linux, the Fantasia jar should be placed in <prefix>/share/java)
379        - VST: fixed crashes on Linux Ardour and EnergyXT
380        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
381          port and audio channel routing for DSSI plugins are now visible.
382        - LV2: use urid and atom extensions instead of deprecated uri-map
383          and event
384        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
385        - LV2: changed number of output channels to 16 stereo, just like
386          the VST and AU plugins

390          sampler's internal MIDI instrument mapping system
391    
392      * Instrument editor interface:
393        - Changed instrument editor plugin interface, providing additional
394          informations like the EngineChannel for which the instrument editor was
395          spawned for. This allows the instrument editors to interact more actively
396          with the sampler.
397    
398      * MIDI driver:
399        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
400          the ALSA sequencer client name

402          there is no reason for this limit
403        - MME: fixed memory handling bug found with cppcheck
404        - MME: removed compiler warning
405        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
406          which allows to retrieve the list of CoreMIDI clients / ports and to connect
407          to them a la JACK, via the usual sampler APIs
408        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
409          the driver will automatically connect to other CoreMIDI clients' ports

411        - added support for MIDI note on velocity filter
412        - CoreMIDI: fixed memory deallocation error
413        - Fixed variable underflow in VirtualMidiDevice, which caused graphical
414          virtual keyboards in frontends / instrument editors being stuck.
415        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
416        - Implemented missing handling of MIDI "running status".
417        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
418        - MME bugfix: driver wasn't closed properly
419        - CoreMIDI: automatically connect to all input sources by default (driver
420          parameter "AUTO_BIND").
421        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
422        - CoreMIDI: fixed minor memory leak
423    
424      * audio driver:
425        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
426        - JACK audio: react on sample rate changes.
427        - JACK audio: react on buffer size changes.
428        - JACK audio: jack_port_get_buffer() was cached and called outside
429          RT context.
430        - ASIO driver: removed compiler warnings
431        - CoreAudio: fixed minor error handling bug
432        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)
433        - JACK audio: return the JACK server's current sample rate as default value
434          for audio device parameter "SAMPLERATE" (fixes #166).
435

484        - Added support for built-in LSCP reference documentation, which will
485          automatically show the relevant LSCP reference section on screen as soon

548          refresh) could cause instruments to be unloaded
549        - Mac OS X: fixed name collision of enum in EffectControl and
550          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
551        - Mac OS X: fixed hanging threads

554        - Fixed possible crashes due to corrupted MIDI/audio device list
555          after MIDI/audio device creation failure
556        - When creating MIDI instrument map entries with "PERSISTENT" type, the
557          instruments were uselessly precached with zero samples, however it still
558          took the full preloading time and on 1st program change the respective
559          instrument was completely reloaded again.
560        - fixed handling of rapid bank select and program change messages
561          sent to the same sampler channel (patch from the Open Octave
562          project, slightly adjusted)

569        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
570          (#176)
571        - more thread safety fixes for the instrument loading thread
572        - sfz/sf2 engine: fixed crash when using small audio fragment size
573        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
574        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
575          introduced in previous fix)
576        - fixed crash when a channel received a program change while
577          playing a note in a key group
578        - fixed erroneous error message piping in VoiceBase.h
579          (labelled "Disk stream not available in time")
580        - Update effects on sample rate & period size changes (to avoid
581          crashes and noise on such transitions).
582        - ignore missing LADSPA paths without ignoring valid LADSPA paths
583          (fixes #208)
584        - Fixed bug in LSCP grammar definition which caused a statement like
585          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
586          practically irrelevant, however it caused problems with the new LSCP
587          shell's auto completion feature).
588        - Fixed MIDI program change messages being ignored if quickly executed
589          after each other (fixes #231).
