40        - support building with older jack versions
41        - support building with spaces in vst sdk path
42        - enabled automake 'subdir-objects' option and moved external
43          source references (vst, au, asio) from makefiles to cpp files,
44          in order to get rid of warnings from automake 1.14
45    
46      * general changes:
47        - Refactoring: moved the independent code from
48          the Gigasampler format engine to base classes
49        - command line option '--profile' is currently disabled, since the
50          respective profiling code is currently broken
51        - Introduced support for optional environment variable
52          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
53          where the sampler shall look for instrument editor plugins
54          (patch by Luis Garrido, slightly modified).
55        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
56        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
57        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
58          note (in this implementation of the sampler its simply hard routed to
59          the 1st effect send of the sampler channel, no matter what the actual
60          effect type is)
61        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
62          note (in this implementation of the sampler its simply hard routed to
63          the 2nd effect send of the sampler channel, no matter what the actual
64          effect type is)
65        - implemented support for internal LADSPA effects
66        - raised limit of program change queue from 100 to 512
67          (as suggested by Alex Stone)
68        - implemented sine LFO, pulse LFO and saw LFO
69        - experimental support for per voice equalization
70        - added command line option --exec-after-init
71        - Introduced new C++ API method:
72          EngineChannel::InstrumentFileName(int index)
73          allowing to retrieve the whole list of files used for the loaded
74          instrument on an engine channel (a.k.a. part). Some GigaStudio
75          instruments for example are splitted over several files like
76          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
77        - Added new C++ API method Sampler::GetGlobalMaxVoices().
78        - Added new C++ API method Sampler::GetGlobalMaxStreams().
79        - Added new C++ API method Sampler::SetGlobalMaxVoices().
80        - Added new C++ API method Sampler::SetGlobalMaxStreams().
81        - Various "const" and "restrict" optimizations.
82        - all engines: add pan CC value to instrument pan parameter before
83          applying panning, instead of using two separate pan functions in
84          series (#182)
85        - added a lock guard class for exception safe mutex handling and
86          used it everywhere appropriate
87        - Immediately apply scale tuning changes to active voices.
88        - Exposed scale tuning to C++ API (along to the already existing standard
89          SysEx way).
90        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
91          and broken for ppc64. (Seq_cst loads and stores are actually not
92          used in LS, so the bug wasn't noticable.)
93        - lsatomic.h: added ARMv7 support
94        - Added support for multiple MIDI input ports per sampler channel (and
95          added various new C++ methods for this new feature / design change, old
96          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
97          as deprecated but are still there and should provide full behavior
98          backward compatibility).
99        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
100          unsafe and caused compilation error with clang 2.x).
101        - Bugfix: only process the latest MIDI program change event.
102        - Introducing the LSCP shell, which provides convenient control of the
103          sampler from the command line by providing LSCP aware features.
104        - VirtualMidiDevice: Added support for program change.
105        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
106        - VirtualMidiDevice: Added support for pitch bend.
107        - Aftertouch: extended API to explicitly handle channel pressure and
108          polyphonic key pressure events (so far polyphonic pressure was not
109          supported at all, and channel pressure was rerouted as CC128 but not
110          used so far).
111        - Added initial support for real-time instrument scripts. The script VM
112          code is shared by all sampler engine implemementations, however only the
113          gig file format currently provides support for storing instrument scripts
114          (as LinuxSampler extension to the original GigaStudio 4 format).
115    
116      * Gigasampler format engine:
117        - implemented the "round robin keyboard" dimension
118        - fixed round robin and random dimensions for cases when number of
119          dimension zones is not a power of two
120        - made round robin use a counter for each region instead of each
121          key
122        - bugfix: pitch LFO controller "internal+aftertouch" was broken
123        - bugfix: filter keyboard tracking was broken
124        - filter performance fix (an unnecessary copy was made of the
125          filter parameters in each sub fragment)
126        - handle special case when pan parameter in gig file has max or
127          min value
128        - Exclusive Groups: don't ever stop voices of the same note,
129          doesn't sound naturally with a drumkit
130        - fixed EG1 modulation when attack or release is zero
131        - Fixed support for 'aftertouch' attenuation controller.
132        - Fixed crash that happened with velocity split sounds under certain
133          conditions (see also previous commit on libgig).

154        - fine-tuned the default velocity curve
155        - added support for transpose
156        - fixed crash when using sw_down/up
157        - improved logic for sw_lokey/hikey/up/down/last
158        - added more v1 aliases to parser
159        - reduced memory usage for sfz data
160        - RT-safeness: avoid malloc in audio thread
161        - fixed a bug that could cause voice stealing to fail

298        - bugfix: line numbers in error messages were wrong after "#include"
299        - added support for float and 32 bit sample files
300    
301      * SoundFont format engine:

311        - AU bugfix: failed to destroy its audio/MIDI devices
312        - Listen to all interfaces on Mac OS X (INADDR_ANY)
313        - VST bugfix: If the host called resume() before and after
314          changing sample rate or block size, the number of channels was
315          incorrectly set to two. This caused silence in Cubase 5.
316        - save engine type (gig, sfz or sf2) in plugin state
317        - VST: when opening Fantasia, look for both 32 and 64 bit Java on

323          specified
324        - LV2 "state" extension support (patch by David Robillard)
325        - VST bugfix: instrument loading hang and crashed the host when
326          the plugin was loaded a second time (#174)
327        - plugin bugfix: instrument loading hang when the plugin was
328          loaded a second time (this time it's for Linux and Mac, previous
329          similar fix was for Windows)
330        - thread safety fixes for the instrument loading thread
331        - LV2: use the new lv2 package if present
332        - VST: try to open Fantasia automatically on Linux and Mac too (on
333          Linux, the Fantasia jar should be placed in <prefix>/share/java)
334        - VST: fixed crashes on Linux Ardour and EnergyXT
335        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
336          port and audio channel routing for DSSI plugins are now visible.
337        - LV2: use urid and atom extensions instead of deprecated uri-map
338          and event

348        - Changed instrument editor plugin interface, providing additional
349          informations like the EngineChannel for which the instrument editor was
350          spawned for. This allows the instrument editors to interact more actively
351          with the sampler.
352    
353      * MIDI driver:
354        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
355          the ALSA sequencer client name

359        - MME: removed compiler warning
360        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
361          which allows to retrieve the list of CoreMIDI clients / ports and to connect
362          to them a la JACK, via the usual sampler APIs
363        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
364          the driver will automatically connect to other CoreMIDI clients' ports
365          (e.g. external MIDI devices being attached to the Mac)
366        - added support for MIDI note on velocity filter
367        - CoreMIDI: fixed memory deallocation error
368        - Fixed variable underflow in VirtualMidiDevice, which caused graphical
369          virtual keyboards in frontends / instrument editors being stuck.
370        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
371        - Implemented missing handling of MIDI "running status".
372        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
373        - MME bugfix: driver wasn't closed properly
374        - CoreMIDI: automatically connect to all input sources by default (driver
375          parameter "AUTO_BIND").
376        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
377        - CoreMIDI: fixed minor memory leak
378    
379      * audio driver:

384          RT context.
385        - ASIO driver: removed compiler warnings
386        - CoreAudio: fixed minor error handling bug
387        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)
388        - JACK audio: return the JACK server's current sample rate as default value
389          for audio device parameter "SAMPLERATE" (fixes #166).
390

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

530          introduced in previous fix)
531        - fixed crash when a channel received a program change while
532          playing a note in a key group
533        - fixed erroneous error message piping in VoiceBase.h
534          (labelled "Disk stream not available in time")
535        - Update effects on sample rate & period size changes (to avoid
536          crashes and noise on such transitions).
537        - ignore missing LADSPA paths without ignoring valid LADSPA paths
538          (fixes #208)
539        - Fixed bug in LSCP grammar definition which caused a statement like
540          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
541          practically irrelevant, however it caused problems with the new LSCP
542          shell's auto completion feature).
543        - Fixed MIDI program change messages being ignored if quickly executed
544          after each other (fixes #231).
