# 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        - 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        - Reload script automatically after being modified by an instrument
55          editor.
56        - NKSP language grammar correction: allow empty event handler bodies
57          like "on note end on".
58    
59    Version 2.0.0 (15 July 2015)
60    
61      * packaging changes:
62        - fixed building with newer MinGW-w64
63        - Mac OS X: support the new dir for Core Audio SDK
64        - Mac OS X: fixed building outside source directory
65        - made sure all source files for hostplugins are included when
66          doing "make dist"
67        - removed empty directories left from the cvs to svn migration
68        - fixed compilation with gcc 4.6.1
69        - another "make dist" fix, for the LV2 plugin
70        - made --enable-pthread-testcancel default on Mac OS X
71        - minor Makefile fix for building lscpparser when build and source
72          directories are separate
73        - Mac OS X: made it possible to specify plugin installation dir to
74          configure
75        - Mac OS X: Makefile fix for the install-strip target
76        - fixed compilation with gcc 4.7
77        - fixed configure script error with old autoconf versions
78        - lsatomic.h: use gcc provided atomic functions if building with
79          gcc 4.7 and C++11
80        - modernized configure script
81        - fixed linkage error when building with
82          LDFLAGS="-Wl,--no-undefined" (#190)
83        - fixed compilation with Clang 3.2
84        - removed usage of deprecated Automake variable INCLUDES
85        - fixed building with C++11
86        - build fix: ChangeFlagRelaxed.h was missing in makefile
87        - build fix: libsndfile compiler flags were missing in some
88          makefiles
89        - fix for building with bison 3.0 (#202)
90        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
91          on the process's main thread
92        - fixed build error on newer MinGW
93        - support building with older jack versions
94        - support building with spaces in vst sdk path
95        - enabled automake 'subdir-objects' option and moved external
96          source references (vst, au, asio) from makefiles to cpp files,
97          in order to get rid of warnings from automake 1.14
98    
99      * general changes:
100        - Refactoring: moved the independent code from
101          the Gigasampler format engine to base classes
102        - command line option '--profile' is currently disabled, since the
103          respective profiling code is currently broken
104        - Introduced support for optional environment variable
105          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
106          where the sampler shall look for instrument editor plugins
107          (patch by Luis Garrido, slightly modified).
108        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
109        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
110        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
111          note (in this implementation of the sampler its simply hard routed to
112          the 1st effect send of the sampler channel, no matter what the actual
113          effect type is)
114        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
115          note (in this implementation of the sampler its simply hard routed to
116          the 2nd effect send of the sampler channel, no matter what the actual
117          effect type is)
118        - implemented support for internal LADSPA effects
119        - raised limit of program change queue from 100 to 512
120          (as suggested by Alex Stone)
121        - implemented sine LFO, pulse LFO and saw LFO
122        - experimental support for per voice equalization
123        - added command line option --exec-after-init
124        - Introduced new C++ API method:
125          EngineChannel::InstrumentFileName(int index)
126          allowing to retrieve the whole list of files used for the loaded
127          instrument on an engine channel (a.k.a. part). Some GigaStudio
128          instruments for example are splitted over several files like
129          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
130        - Added new C++ API method Sampler::GetGlobalMaxVoices().
131        - Added new C++ API method Sampler::GetGlobalMaxStreams().
132        - Added new C++ API method Sampler::SetGlobalMaxVoices().
133        - Added new C++ API method Sampler::SetGlobalMaxStreams().
134        - Various "const" and "restrict" optimizations.
135        - all engines: add pan CC value to instrument pan parameter before
136          applying panning, instead of using two separate pan functions in
137          series (#182)
138        - added a lock guard class for exception safe mutex handling and
139          used it everywhere appropriate
140        - Immediately apply scale tuning changes to active voices.
141        - Exposed scale tuning to C++ API (along to the already existing standard
142          SysEx way).
143        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
144          and broken for ppc64. (Seq_cst loads and stores are actually not
145          used in LS, so the bug wasn't noticable.)
146        - lsatomic.h: added ARMv7 support
147        - Added support for multiple MIDI input ports per sampler channel (and
148          added various new C++ methods for this new feature / design change, old
149          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
150          as deprecated but are still there and should provide full behavior
151          backward compatibility).
152        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
153          unsafe and caused compilation error with clang 2.x).
154        - Bugfix: only process the latest MIDI program change event.
155        - Introducing the LSCP shell, which provides convenient control of the
156          sampler from the command line by providing LSCP aware features.
157        - VirtualMidiDevice: Added support for program change.
158        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
159        - VirtualMidiDevice: Added support for pitch bend.
160        - Aftertouch: extended API to explicitly handle channel pressure and
161          polyphonic key pressure events (so far polyphonic pressure was not
162          supported at all, and channel pressure was rerouted as CC128 but not
163          used so far).
164        - Added initial support for real-time instrument scripts. The script VM
165          code is shared by all sampler engine implemementations, however only the
166          gig file format currently provides support for storing instrument scripts
167          (as LinuxSampler extension to the original GigaStudio 4 format).
168    
169      * Gigasampler format engine:
170        - implemented the "round robin keyboard" dimension
171        - fixed round robin and random dimensions for cases when number of
172          dimension zones is not a power of two
173        - made round robin use a counter for each region instead of each
174          key
175        - bugfix: pitch LFO controller "internal+aftertouch" was broken
176        - bugfix: filter keyboard tracking was broken
177        - filter performance fix (an unnecessary copy was made of the
178          filter parameters in each sub fragment)
179        - handle special case when pan parameter in gig file has max or
180          min value
181        - Exclusive Groups: don't ever stop voices of the same note,
182          doesn't sound naturally with a drumkit
183        - fixed EG1 modulation when attack or release is zero
184        - Fixed support for 'aftertouch' attenuation controller.
185        - Fixed crash that happened with velocity split sounds under certain
186          conditions (see also previous commit on libgig).
187        - fixed behaviour of filter LFO
188

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

337        - bugfix: looping was disabled if loop_start was set to 0
338        - allow regions with end=-1 to turn off other regions using the
339          group and off_by opcodes (#168)

350          after each "#include", only after the main file is parsed
351        - bugfix: line numbers in error messages were wrong after "#include"
352        - added support for float and 32 bit sample files
353    
354      * SoundFont format engine:

364        - AU bugfix: failed to destroy its audio/MIDI devices
365        - Listen to all interfaces on Mac OS X (INADDR_ANY)
366        - VST bugfix: If the host called resume() before and after
367          changing sample rate or block size, the number of channels was
368          incorrectly set to two. This caused silence in Cubase 5.
369        - save engine type (gig, sfz or sf2) in plugin state
370        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
371          64 bit Windows
372        - AU: changed number of output channels from one stereo to 16
373          stereo

383        - thread safety fixes for the instrument loading thread
384        - LV2: use the new lv2 package if present
385        - VST: try to open Fantasia automatically on Linux and Mac too (on
386          Linux, the Fantasia jar should be placed in <prefix>/share/java)
387        - VST: fixed crashes on Linux Ardour and EnergyXT
388        - DSSI bugfix: it wasn't possible to change engine type. The MIDI

401        - Changed instrument editor plugin interface, providing additional
402          informations like the EngineChannel for which the instrument editor was
403          spawned for. This allows the instrument editors to interact more actively
404          with the sampler.
405    
406      * MIDI driver:
407        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
408          the ALSA sequencer client name

410          there is no reason for this limit
411        - MME: fixed memory handling bug found with cppcheck
412        - MME: removed compiler warning
413        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
414          which allows to retrieve the list of CoreMIDI clients / ports and to connect
415          to them a la JACK, via the usual sampler APIs
416        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
417          the driver will automatically connect to other CoreMIDI clients' ports

422          virtual keyboards in frontends / instrument editors being stuck.
423        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
424        - Implemented missing handling of MIDI "running status".
425        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
426        - MME bugfix: driver wasn't closed properly
427        - CoreMIDI: automatically connect to all input sources by default (driver
428          parameter "AUTO_BIND").
429        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
430        - CoreMIDI: fixed minor memory leak
431    
432      * audio driver:

437          RT context.
438        - ASIO driver: removed compiler warnings
439        - CoreAudio: fixed minor error handling bug
440        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)

563          after MIDI/audio device creation failure
564        - When creating MIDI instrument map entries with "PERSISTENT" type, the
565          instruments were uselessly precached with zero samples, however it still
566          took the full preloading time and on 1st program change the respective
567          instrument was completely reloaded again.
568        - fixed handling of rapid bank select and program change messages
569          sent to the same sampler channel (patch from the Open Octave

582        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
583          introduced in previous fix)
584        - fixed crash when a channel received a program change while
585          playing a note in a key group
586        - fixed erroneous error message piping in VoiceBase.h
587          (labelled "Disk stream not available in time")
588        - Update effects on sample rate & period size changes (to avoid
589          crashes and noise on such transitions).
590        - ignore missing LADSPA paths without ignoring valid LADSPA paths
591          (fixes #208)
592        - Fixed bug in LSCP grammar definition which caused a statement like
593          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
594          practically irrelevant, however it caused problems with the new LSCP
595          shell's auto completion feature).
596        - Fixed MIDI program change messages being ignored if quickly executed
597          after each other (fixes #231).
