# 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)
48    
49      * packaging changes:
50        - fixed building with newer MinGW-w64
51        - Mac OS X: support the new dir for Core Audio SDK
52        - Mac OS X: fixed building outside source directory
53        - made sure all source files for hostplugins are included when
54          doing "make dist"
55        - removed empty directories left from the cvs to svn migration
56        - fixed compilation with gcc 4.6.1
57        - another "make dist" fix, for the LV2 plugin
58        - made --enable-pthread-testcancel default on Mac OS X
59        - minor Makefile fix for building lscpparser when build and source
60          directories are separate
61        - Mac OS X: made it possible to specify plugin installation dir to
62          configure
63        - Mac OS X: Makefile fix for the install-strip target
64        - fixed compilation with gcc 4.7
65        - fixed configure script error with old autoconf versions
66        - lsatomic.h: use gcc provided atomic functions if building with
67          gcc 4.7 and C++11
68        - modernized configure script
69        - fixed linkage error when building with
70          LDFLAGS="-Wl,--no-undefined" (#190)
71        - fixed compilation with Clang 3.2
72        - removed usage of deprecated Automake variable INCLUDES
73        - fixed building with C++11
74        - build fix: ChangeFlagRelaxed.h was missing in makefile
75        - build fix: libsndfile compiler flags were missing in some
76          makefiles
77        - fix for building with bison 3.0 (#202)
78        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
79          on the process's main thread
80        - fixed build error on newer MinGW
81        - support building with older jack versions
82        - support building with spaces in vst sdk path
83        - enabled automake 'subdir-objects' option and moved external
84          source references (vst, au, asio) from makefiles to cpp files,
85          in order to get rid of warnings from automake 1.14
86    
87      * general changes:
88        - Refactoring: moved the independent code from
89          the Gigasampler format engine to base classes
90        - command line option '--profile' is currently disabled, since the
91          respective profiling code is currently broken
92        - Introduced support for optional environment variable
93          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
94          where the sampler shall look for instrument editor plugins
95          (patch by Luis Garrido, slightly modified).
96        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
97        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
98        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
99          note (in this implementation of the sampler its simply hard routed to
100          the 1st effect send of the sampler channel, no matter what the actual
101          effect type is)
102        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
103          note (in this implementation of the sampler its simply hard routed to
104          the 2nd effect send of the sampler channel, no matter what the actual
105          effect type is)
106        - implemented support for internal LADSPA effects
107        - raised limit of program change queue from 100 to 512
108          (as suggested by Alex Stone)
109        - implemented sine LFO, pulse LFO and saw LFO
110        - experimental support for per voice equalization
111        - added command line option --exec-after-init
112        - Introduced new C++ API method:
113          EngineChannel::InstrumentFileName(int index)
114          allowing to retrieve the whole list of files used for the loaded
115          instrument on an engine channel (a.k.a. part). Some GigaStudio
116          instruments for example are splitted over several files like
117          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
118        - Added new C++ API method Sampler::GetGlobalMaxVoices().
119        - Added new C++ API method Sampler::GetGlobalMaxStreams().
120        - Added new C++ API method Sampler::SetGlobalMaxVoices().
121        - Added new C++ API method Sampler::SetGlobalMaxStreams().
122        - Various "const" and "restrict" optimizations.
123        - all engines: add pan CC value to instrument pan parameter before
124          applying panning, instead of using two separate pan functions in
125          series (#182)
126        - added a lock guard class for exception safe mutex handling and
127          used it everywhere appropriate
128        - Immediately apply scale tuning changes to active voices.
129        - Exposed scale tuning to C++ API (along to the already existing standard
130          SysEx way).
131        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
132          and broken for ppc64. (Seq_cst loads and stores are actually not
133          used in LS, so the bug wasn't noticable.)
134        - lsatomic.h: added ARMv7 support
135        - Added support for multiple MIDI input ports per sampler channel (and
136          added various new C++ methods for this new feature / design change, old
137          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
138          as deprecated but are still there and should provide full behavior
139          backward compatibility).
140        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
141          unsafe and caused compilation error with clang 2.x).
142        - Bugfix: only process the latest MIDI program change event.
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).
156    
157      * Gigasampler format engine:
158        - implemented the "round robin keyboard" dimension
159        - fixed round robin and random dimensions for cases when number of
160          dimension zones is not a power of two
161        - made round robin use a counter for each region instead of each
162          key
163        - bugfix: pitch LFO controller "internal+aftertouch" was broken
164        - bugfix: filter keyboard tracking was broken
165        - filter performance fix (an unnecessary copy was made of the
166          filter parameters in each sub fragment)
167        - handle special case when pan parameter in gig file has max or
168          min value
169        - Exclusive Groups: don't ever stop voices of the same note,
170          doesn't sound naturally with a drumkit
171        - fixed EG1 modulation when attack or release is zero
172        - Fixed support for 'aftertouch' attenuation controller.
173        - Fixed crash that happened with velocity split sounds under certain
174          conditions (see also previous commit on libgig).
175        - fixed behaviour of filter LFO

183        - added support for trigger=first, trigger=legato and sw_previous
184        - allow non-numerical key values ("C#4" for example)
185        - "key" opcode now sets pitch_keycenter too
186        - fixed error when unloading instrument with same sample used by
187          multiple regions

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

207        - added support for loop_mode=one_shot
208        - fixed playback of 16 bit wav files on big endian CPUs
209        - added support for Ogg Vorbis sample files
210        - use loop markers from sample file if loop_start and loop_end are
211          not set in sfz file

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

367          the plugin was loaded a second time (#174)
368        - plugin bugfix: instrument loading hang when the plugin was
369          loaded a second time (this time it's for Linux and Mac, previous
370          similar fix was for Windows)
371        - thread safety fixes for the instrument loading thread
372        - LV2: use the new lv2 package if present
373        - VST: try to open Fantasia automatically on Linux and Mac too (on
374          Linux, the Fantasia jar should be placed in <prefix>/share/java)
375        - VST: fixed crashes on Linux Ardour and EnergyXT
376        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
377          port and audio channel routing for DSSI plugins are now visible.
378        - LV2: use urid and atom extensions instead of deprecated uri-map
379          and event
380        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
381        - LV2: changed number of output channels to 16 stereo, just like
382          the VST and AU plugins
383        - LV2: fixed save/restore of SFZ state (patch by David Robillard)
384        - LV2: made LV2 plugin buildable on Windows and Mac
385        - VST: implemented retrieval and switching of programs using the
386          sampler's internal MIDI instrument mapping system
387    
388      * Instrument editor interface:
389        - Changed instrument editor plugin interface, providing additional
390          informations like the EngineChannel for which the instrument editor was
391          spawned for. This allows the instrument editors to interact more actively
392          with the sampler.
393    
394      * MIDI driver:
395        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
396          the ALSA sequencer client name
397        - removed limit of maximum amount of MIDI ports per MIDI device, since
398          there is no reason for this limit
399        - MME: fixed memory handling bug found with cppcheck
400        - MME: removed compiler warning
401        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
402          which allows to retrieve the list of CoreMIDI clients / ports and to connect
403          to them a la JACK, via the usual sampler APIs
404        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
405          the driver will automatically connect to other CoreMIDI clients' ports
406          (e.g. external MIDI devices being attached to the Mac)
407        - added support for MIDI note on velocity filter
408        - CoreMIDI: fixed memory deallocation error
409        - Fixed variable underflow in VirtualMidiDevice, which caused graphical
410          virtual keyboards in frontends / instrument editors being stuck.
411        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
412        - Implemented missing handling of MIDI "running status".
413        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
414        - MME bugfix: driver wasn't closed properly
415        - CoreMIDI: automatically connect to all input sources by default (driver
416          parameter "AUTO_BIND").
417        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
418        - CoreMIDI: fixed minor memory leak
419    
420      * audio driver:
421        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
422        - JACK audio: react on sample rate changes.
423        - JACK audio: react on buffer size changes.
424        - JACK audio: jack_port_get_buffer() was cached and called outside
425          RT context.
426        - ASIO driver: removed compiler warnings
427        - CoreAudio: fixed minor error handling bug
428        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)
429        - JACK audio: return the JACK server's current sample rate as default value
430          for audio device parameter "SAMPLERATE" (fixes #166).
431    
432      * LSCP server:
433        - added support for sending MIDI CC messages via LSCP command

480        - Added support for built-in LSCP reference documentation, which will
481          automatically show the relevant LSCP reference section on screen as soon
482          as one specific LSCP command was detected while typing on the command
483          line.
484

538          channel to a different engine type
539        - fixed crash when deleting a sampler channel or changing engine
540          type while an instrument load was in progress
541        - bugfix: playing a note while changing the instrument could cause
542          a crash, or give "Handing back unknown region" error messages
543        - bugfix: calling SET VOICES (which Fantasia does on start and
544          refresh) could cause instruments to be unloaded
545        - Mac OS X: fixed name collision of enum in EffectControl and
546          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
547        - Mac OS X: fixed hanging threads
548        - Windows: disabled the previous thread fix on non-Mac systems, as
549          it caused hanging threads on Windows
550        - Fixed possible crashes due to corrupted MIDI/audio device list
551          after MIDI/audio device creation failure
552        - When creating MIDI instrument map entries with "PERSISTENT" type, the
553          instruments were uselessly precached with zero samples, however it still
554          took the full preloading time and on 1st program change the respective
555          instrument was completely reloaded again.
556        - fixed handling of rapid bank select and program change messages
557          sent to the same sampler channel (patch from the Open Octave
558          project, slightly adjusted)

565        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
566          (#176)
567        - more thread safety fixes for the instrument loading thread
568        - sfz/sf2 engine: fixed crash when using small audio fragment size
569        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
570        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
571          introduced in previous fix)
572        - fixed crash when a channel received a program change while
573          playing a note in a key group
574        - fixed erroneous error message piping in VoiceBase.h
575          (labelled "Disk stream not available in time")
576        - Update effects on sample rate & period size changes (to avoid
577          crashes and noise on such transitions).
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).
