# 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        - Fix: Release trigger voices were not spawned on sustain pedal up
24          (CC #64) events.
25        - Fix: Release trigger voices can now also distinguish correctly between
26          note-off and sustain pedal up events.
27    
28      * packaging changes:
29        - removed unnecessary dependency to libuuid
30          (originated by libgig's usage of it)
31        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
32          auto detect whether it (sh/c)ould output its messages in color.
33    
34      * Real-time instrument scripts:
35        - Implemented scheduler for delayed MIDI events and for suspended scripts.
36        - Built-in script function "wait()": implemented support for function's
37          "duration-us" argument, thus scripts using this function are now
38          correctly resumed after the requested amount of microseconds.
39        - Built-in script function "play_note()": implemented support for
40          function's "duration-us" argument, thus notes triggered with this
41          argument are now correctly released after the requested amount of
42          microseconds.
43        - Fix: script events were not cleared when engine channel was reset,
44          potentially causing undefined behavior.
45        - Fixed crash which happened when trying to reference an undeclared
46          variable.
47        - Built-in script function "play_note()": Added support for passing
48          special value -1 for "duration-us" argument, which will cause the
49          triggered note to be released once the original note was released.
50        - Instrument script classes now exported with the liblinuxsampler C++ API.
51        - Added new API method ScriptVM::syntaxHighlighting() which provides
52          a convenient syntax highlighting backend for external instrument
53          script editor applications.
54        - Added new C++ API class "ScriptVMFactory".
55        - Extended parser issues to provide not only first line and first
56          column, but also last line and last column of issue (thus marking
57          the precise span of the issue within the source code).
58        - Reload script automatically after being modified by an instrument
59          editor.
60        - NKSP language grammar correction: allow empty event handler bodies
61          like "on note end on".
62    
63    Version 2.0.0 (15 July 2015)
64    
65      * packaging changes:
66        - fixed building with newer MinGW-w64
67        - Mac OS X: support the new dir for Core Audio SDK
68        - Mac OS X: fixed building outside source directory
69        - made sure all source files for hostplugins are included when
70          doing "make dist"
71        - removed empty directories left from the cvs to svn migration
72        - fixed compilation with gcc 4.6.1
73        - another "make dist" fix, for the LV2 plugin
74        - made --enable-pthread-testcancel default on Mac OS X
75        - minor Makefile fix for building lscpparser when build and source
76          directories are separate
77        - Mac OS X: made it possible to specify plugin installation dir to
78          configure
79        - Mac OS X: Makefile fix for the install-strip target
80        - fixed compilation with gcc 4.7
81        - fixed configure script error with old autoconf versions
82        - lsatomic.h: use gcc provided atomic functions if building with
83          gcc 4.7 and C++11
84        - modernized configure script
85        - fixed linkage error when building with
86          LDFLAGS="-Wl,--no-undefined" (#190)
87        - fixed compilation with Clang 3.2
88        - removed usage of deprecated Automake variable INCLUDES
89        - fixed building with C++11
90        - build fix: ChangeFlagRelaxed.h was missing in makefile
91        - build fix: libsndfile compiler flags were missing in some
92          makefiles
93        - fix for building with bison 3.0 (#202)
94        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
95          on the process's main thread
96        - fixed build error on newer MinGW
97        - support building with older jack versions
98        - support building with spaces in vst sdk path
99        - enabled automake 'subdir-objects' option and moved external
100          source references (vst, au, asio) from makefiles to cpp files,
101          in order to get rid of warnings from automake 1.14
102    
103      * general changes:
104        - Refactoring: moved the independent code from
105          the Gigasampler format engine to base classes
106        - command line option '--profile' is currently disabled, since the
107          respective profiling code is currently broken
108        - Introduced support for optional environment variable
109          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
110          where the sampler shall look for instrument editor plugins
111          (patch by Luis Garrido, slightly modified).
112        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
113        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
114        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
115          note (in this implementation of the sampler its simply hard routed to
116          the 1st effect send of the sampler channel, no matter what the actual
117          effect type is)
118        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
119          note (in this implementation of the sampler its simply hard routed to
120          the 2nd effect send of the sampler channel, no matter what the actual
121          effect type is)
122        - implemented support for internal LADSPA effects
123        - raised limit of program change queue from 100 to 512
124          (as suggested by Alex Stone)
125        - implemented sine LFO, pulse LFO and saw LFO
126        - experimental support for per voice equalization
127        - added command line option --exec-after-init
128        - Introduced new C++ API method:
129          EngineChannel::InstrumentFileName(int index)
130          allowing to retrieve the whole list of files used for the loaded
131          instrument on an engine channel (a.k.a. part). Some GigaStudio
132          instruments for example are splitted over several files like
133          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
134        - Added new C++ API method Sampler::GetGlobalMaxVoices().
135        - Added new C++ API method Sampler::GetGlobalMaxStreams().
136        - Added new C++ API method Sampler::SetGlobalMaxVoices().
137        - Added new C++ API method Sampler::SetGlobalMaxStreams().
138        - Various "const" and "restrict" optimizations.
139        - all engines: add pan CC value to instrument pan parameter before
140          applying panning, instead of using two separate pan functions in
141          series (#182)
142        - added a lock guard class for exception safe mutex handling and
143          used it everywhere appropriate
144        - Immediately apply scale tuning changes to active voices.
145        - Exposed scale tuning to C++ API (along to the already existing standard
146          SysEx way).
147        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
148          and broken for ppc64. (Seq_cst loads and stores are actually not
149          used in LS, so the bug wasn't noticable.)
150        - lsatomic.h: added ARMv7 support
151        - Added support for multiple MIDI input ports per sampler channel (and
152          added various new C++ methods for this new feature / design change, old
153          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
154          as deprecated but are still there and should provide full behavior
155          backward compatibility).
156        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
157          unsafe and caused compilation error with clang 2.x).
158        - Bugfix: only process the latest MIDI program change event.
159        - Introducing the LSCP shell, which provides convenient control of the
160          sampler from the command line by providing LSCP aware features.
161        - VirtualMidiDevice: Added support for program change.
162        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
163        - VirtualMidiDevice: Added support for pitch bend.
164        - Aftertouch: extended API to explicitly handle channel pressure and
165          polyphonic key pressure events (so far polyphonic pressure was not
166          supported at all, and channel pressure was rerouted as CC128 but not
167          used so far).
168        - Added initial support for real-time instrument scripts. The script VM
169          code is shared by all sampler engine implemementations, however only the
170          gig file format currently provides support for storing instrument scripts
171          (as LinuxSampler extension to the original GigaStudio 4 format).
172    
173      * Gigasampler format engine:
174        - implemented the "round robin keyboard" dimension
175        - fixed round robin and random dimensions for cases when number of
176          dimension zones is not a power of two
177        - made round robin use a counter for each region instead of each
178          key
179        - bugfix: pitch LFO controller "internal+aftertouch" was broken
180        - bugfix: filter keyboard tracking was broken
181        - filter performance fix (an unnecessary copy was made of the
182          filter parameters in each sub fragment)
183        - handle special case when pan parameter in gig file has max or
184          min value
185        - Exclusive Groups: don't ever stop voices of the same note,
186          doesn't sound naturally with a drumkit
187        - fixed EG1 modulation when attack or release is zero
188        - Fixed support for 'aftertouch' attenuation controller.
189        - Fixed crash that happened with velocity split sounds under certain
190          conditions (see also previous commit on libgig).

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

208        - added support for random, seq_position, seq_length and volume
209        - added v1 LFO opcodes to parser (no support in engine yet)
210        - added support for amp_veltrack and amp_velcurve_N
211        - fine-tuned the default velocity curve
212        - added support for transpose
213        - fixed crash when using sw_down/up
214        - improved logic for sw_lokey/hikey/up/down/last
215        - added more v1 aliases to parser
216        - reduced memory usage for sfz data
217        - RT-safeness: avoid malloc in audio thread
218        - fixed a bug that could cause voice stealing to fail
219        - optimized sample lookup
220        - improved support for exclusive groups (group, off_by and

340          used
341        - bugfix: looping was disabled if loop_start was set to 0
342        - allow regions with end=-1 to turn off other regions using the

355        - bugfix: line numbers in error messages were wrong after "#include"
356        - added support for float and 32 bit sample files
357    
358      * SoundFont format engine:

368        - AU bugfix: failed to destroy its audio/MIDI devices
369        - Listen to all interfaces on Mac OS X (INADDR_ANY)
370        - VST bugfix: If the host called resume() before and after
371          changing sample rate or block size, the number of channels was
372          incorrectly set to two. This caused silence in Cubase 5.
373        - save engine type (gig, sfz or sf2) in plugin state
374        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
375          64 bit Windows
376        - AU: changed number of output channels from one stereo to 16
377          stereo

387        - thread safety fixes for the instrument loading thread
388        - LV2: use the new lv2 package if present
389        - VST: try to open Fantasia automatically on Linux and Mac too (on
390          Linux, the Fantasia jar should be placed in <prefix>/share/java)
391        - VST: fixed crashes on Linux Ardour and EnergyXT
392        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
393          port and audio channel routing for DSSI plugins are now visible.

405        - Changed instrument editor plugin interface, providing additional
406          informations like the EngineChannel for which the instrument editor was
407          spawned for. This allows the instrument editors to interact more actively
408          with the sampler.
409    
410      * MIDI driver:
411        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
412          the ALSA sequencer client name

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

423        - added support for MIDI note on velocity filter
424        - CoreMIDI: fixed memory deallocation error
425        - Fixed variable underflow in VirtualMidiDevice, which caused graphical
426          virtual keyboards in frontends / instrument editors being stuck.
427        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
428        - Implemented missing handling of MIDI "running status".
429        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
430        - MME bugfix: driver wasn't closed properly
431        - CoreMIDI: automatically connect to all input sources by default (driver
432          parameter "AUTO_BIND").
433        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
434        - CoreMIDI: fixed minor memory leak
435    
436      * audio driver:

441          RT context.
442        - ASIO driver: removed compiler warnings
443        - CoreAudio: fixed minor error handling bug
444        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)

562          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
563        - Mac OS X: fixed hanging threads

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

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