# 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        - Implemented built-in script function "change_vol()".
63        - Implemented built-in script function "change_tune()".
64        - Implemented built-in script function "change_pan()".
65        - Implemented built-in script function "change_cutoff()".
66        - Implemented built-in script function "change_reso()".
67        - Implemented built-in script function "event_status()".
68        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
69          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
70          "event_status()" function.
71        - NKSP language: Added support for bitwise operators ".or.", ".and."
72          and ".not.".
73        - NKSP language scanner: Fixed IDs matching to require at least one
74          character (i.e. when matching function names or variable names).
75        - NKSP language scanner: disabled unusued rules.
76        - Fixed behavior of play_note() and note_off() functions which must
77          be distinguished engine internally from "real" MIDI note on/off
78          events in order to avoid misbehaviors like hanging notes.
79    
80    Version 2.0.0 (15 July 2015)
81    
82      * packaging changes:
83        - fixed building with newer MinGW-w64
84        - Mac OS X: support the new dir for Core Audio SDK
85        - Mac OS X: fixed building outside source directory
86        - made sure all source files for hostplugins are included when
87          doing "make dist"
88        - removed empty directories left from the cvs to svn migration
89        - fixed compilation with gcc 4.6.1
90        - another "make dist" fix, for the LV2 plugin
91        - made --enable-pthread-testcancel default on Mac OS X
92        - minor Makefile fix for building lscpparser when build and source
93          directories are separate
94        - Mac OS X: made it possible to specify plugin installation dir to
95          configure
96        - Mac OS X: Makefile fix for the install-strip target
97        - fixed compilation with gcc 4.7
98        - fixed configure script error with old autoconf versions
99        - lsatomic.h: use gcc provided atomic functions if building with
100          gcc 4.7 and C++11
101        - modernized configure script
102        - fixed linkage error when building with
103          LDFLAGS="-Wl,--no-undefined" (#190)
104        - fixed compilation with Clang 3.2
105        - removed usage of deprecated Automake variable INCLUDES

111        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
112          on the process's main thread
113        - fixed build error on newer MinGW
114        - support building with older jack versions
115        - support building with spaces in vst sdk path
116        - enabled automake 'subdir-objects' option and moved external
117          source references (vst, au, asio) from makefiles to cpp files,
118          in order to get rid of warnings from automake 1.14
119    
120      * general changes:
121        - Refactoring: moved the independent code from
122          the Gigasampler format engine to base classes
123        - command line option '--profile' is currently disabled, since the
124          respective profiling code is currently broken
125        - Introduced support for optional environment variable
126          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
127          where the sampler shall look for instrument editor plugins
128          (patch by Luis Garrido, slightly modified).
129        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
130        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
131        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
132          note (in this implementation of the sampler its simply hard routed to
133          the 1st effect send of the sampler channel, no matter what the actual
134          effect type is)
135        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
136          note (in this implementation of the sampler its simply hard routed to
137          the 2nd effect send of the sampler channel, no matter what the actual
138          effect type is)
139        - implemented support for internal LADSPA effects
140        - raised limit of program change queue from 100 to 512
141          (as suggested by Alex Stone)
142        - implemented sine LFO, pulse LFO and saw LFO
143        - experimental support for per voice equalization
144        - added command line option --exec-after-init
145        - Introduced new C++ API method:
146          EngineChannel::InstrumentFileName(int index)
147          allowing to retrieve the whole list of files used for the loaded
148          instrument on an engine channel (a.k.a. part). Some GigaStudio
149          instruments for example are splitted over several files like
150          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
151        - Added new C++ API method Sampler::GetGlobalMaxVoices().
152        - Added new C++ API method Sampler::GetGlobalMaxStreams().
153        - Added new C++ API method Sampler::SetGlobalMaxVoices().
154        - Added new C++ API method Sampler::SetGlobalMaxStreams().
155        - Various "const" and "restrict" optimizations.
156        - all engines: add pan CC value to instrument pan parameter before
157          applying panning, instead of using two separate pan functions in
158          series (#182)
159        - added a lock guard class for exception safe mutex handling and
160          used it everywhere appropriate
161        - Immediately apply scale tuning changes to active voices.
162        - Exposed scale tuning to C++ API (along to the already existing standard
163          SysEx way).
164        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
165          and broken for ppc64. (Seq_cst loads and stores are actually not
166          used in LS, so the bug wasn't noticable.)
167        - lsatomic.h: added ARMv7 support
168        - Added support for multiple MIDI input ports per sampler channel (and
169          added various new C++ methods for this new feature / design change, old
170          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
171          as deprecated but are still there and should provide full behavior
172          backward compatibility).
173        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
174          unsafe and caused compilation error with clang 2.x).
175        - Bugfix: only process the latest MIDI program change event.
176        - Introducing the LSCP shell, which provides convenient control of the
177          sampler from the command line by providing LSCP aware features.
178        - VirtualMidiDevice: Added support for program change.
179        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
180        - VirtualMidiDevice: Added support for pitch bend.
181        - Aftertouch: extended API to explicitly handle channel pressure and
182          polyphonic key pressure events (so far polyphonic pressure was not
183          supported at all, and channel pressure was rerouted as CC128 but not
184          used so far).
185        - Added initial support for real-time instrument scripts. The script VM
186          code is shared by all sampler engine implemementations, however only the
187          gig file format currently provides support for storing instrument scripts
188          (as LinuxSampler extension to the original GigaStudio 4 format).
189    
190      * Gigasampler format engine:
191        - implemented the "round robin keyboard" dimension
192        - fixed round robin and random dimensions for cases when number of
193          dimension zones is not a power of two
194        - made round robin use a counter for each region instead of each
195          key
196        - bugfix: pitch LFO controller "internal+aftertouch" was broken
197        - bugfix: filter keyboard tracking was broken
198        - filter performance fix (an unnecessary copy was made of the
199          filter parameters in each sub fragment)
200        - handle special case when pan parameter in gig file has max or
201          min value
202        - Exclusive Groups: don't ever stop voices of the same note,
203          doesn't sound naturally with a drumkit
204        - fixed EG1 modulation when attack or release is zero
205        - Fixed support for 'aftertouch' attenuation controller.
206        - Fixed crash that happened with velocity split sounds under certain
207          conditions (see also previous commit on libgig).

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

225        - added support for random, seq_position, seq_length and volume
226        - added v1 LFO opcodes to parser (no support in engine yet)
227        - added support for amp_veltrack and amp_velcurve_N
228        - fine-tuned the default velocity curve
229        - added support for transpose
230        - fixed crash when using sw_down/up
231        - improved logic for sw_lokey/hikey/up/down/last
232        - added more v1 aliases to parser
233        - reduced memory usage for sfz data
234        - RT-safeness: avoid malloc in audio thread
235        - fixed a bug that could cause voice stealing to fail
236        - optimized sample lookup
237        - improved support for exclusive groups (group, off_by and

357          used
358        - bugfix: looping was disabled if loop_start was set to 0
359        - allow regions with end=-1 to turn off other regions using the

371          after each "#include", only after the main file is parsed
372        - bugfix: line numbers in error messages were wrong after "#include"
373        - added support for float and 32 bit sample files
374    
375      * SoundFont format engine:

385        - AU bugfix: failed to destroy its audio/MIDI devices
386        - Listen to all interfaces on Mac OS X (INADDR_ANY)
387        - VST bugfix: If the host called resume() before and after
388          changing sample rate or block size, the number of channels was
389          incorrectly set to two. This caused silence in Cubase 5.
390        - save engine type (gig, sfz or sf2) in plugin state
391        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
392          64 bit Windows
393        - AU: changed number of output channels from one stereo to 16
394          stereo

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

422        - Changed instrument editor plugin interface, providing additional
423          informations like the EngineChannel for which the instrument editor was
424          spawned for. This allows the instrument editors to interact more actively
425          with the sampler.
426    
427      * MIDI driver:
428        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
429          the ALSA sequencer client name

431          there is no reason for this limit
432        - MME: fixed memory handling bug found with cppcheck
433        - MME: removed compiler warning
434        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
435          which allows to retrieve the list of CoreMIDI clients / ports and to connect
436          to them a la JACK, via the usual sampler APIs
437        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
438          the driver will automatically connect to other CoreMIDI clients' ports

443          virtual keyboards in frontends / instrument editors being stuck.
444        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
445        - Implemented missing handling of MIDI "running status".
446        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
447        - MME bugfix: driver wasn't closed properly
448        - CoreMIDI: automatically connect to all input sources by default (driver
449          parameter "AUTO_BIND").
450        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
451        - CoreMIDI: fixed minor memory leak
452    
453      * audio driver:
454        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
455        - JACK audio: react on sample rate changes.

458          RT context.
459        - ASIO driver: removed compiler warnings
460        - CoreAudio: fixed minor error handling bug
461        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)

577          refresh) could cause instruments to be unloaded
578        - Mac OS X: fixed name collision of enum in EffectControl and
579          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
580        - Mac OS X: fixed hanging threads

584          after MIDI/audio device creation failure
585        - When creating MIDI instrument map entries with "PERSISTENT" type, the
586          instruments were uselessly precached with zero samples, however it still
587          took the full preloading time and on 1st program change the respective
588          instrument was completely reloaded again.
589        - fixed handling of rapid bank select and program change messages
590          sent to the same sampler channel (patch from the Open Octave
591          project, slightly adjusted)

604          introduced in previous fix)
605        - fixed crash when a channel received a program change while
606          playing a note in a key group
607        - fixed erroneous error message piping in VoiceBase.h
608          (labelled "Disk stream not available in time")
609        - Update effects on sample rate & period size changes (to avoid
610          crashes and noise on such transitions).
611        - ignore missing LADSPA paths without ignoring valid LADSPA paths
612          (fixes #208)
613        - Fixed bug in LSCP grammar definition which caused a statement like
614          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
615          practically irrelevant, however it caused problems with the new LSCP
616          shell's auto completion feature).
617        - Fixed MIDI program change messages being ignored if quickly executed
618          after each other (fixes #231).
