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

149        - fine-tuned the default velocity curve
150        - added support for transpose
151        - fixed crash when using sw_down/up
152        - improved logic for sw_lokey/hikey/up/down/last
153        - added more v1 aliases to parser
154        - reduced memory usage for sfz data
155        - RT-safeness: avoid malloc in audio thread

292          after each "#include", only after the main file is parsed
293        - bugfix: line numbers in error messages were wrong after "#include"
294    
295      * SoundFont format engine:
296        - Initial implementation (not usable yet)
297        - RT-safeness: avoid malloc in audio thread
298        - fixed a bug that could cause voice stealing to fail

300        - initial implementation of Vibrato LFO and Modulation LFO
301        - initial implementation of cutoff filter
302        - use linear decay and release for filter and pitch EG
303    
304      * Host plugins (VST, AU, LV2, DSSI):
305        - AU bugfix: failed to destroy its audio/MIDI devices
306        - Listen to all interfaces on Mac OS X (INADDR_ANY)
307        - VST bugfix: If the host called resume() before and after
308          changing sample rate or block size, the number of channels was
309          incorrectly set to two. This caused silence in Cubase 5.
310        - save engine type (gig, sfz or sf2) in plugin state
311        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
312          64 bit Windows
313        - AU: changed number of output channels from one stereo to 16
314          stereo
315        - VST: made it possible to build the VST plugin for Mac
316        - AU: link AU plugin dynamically if --disable-shared isn't
317          specified
318        - LV2 "state" extension support (patch by David Robillard)
319        - VST bugfix: instrument loading hang and crashed the host when
320          the plugin was loaded a second time (#174)
321        - plugin bugfix: instrument loading hang when the plugin was
322          loaded a second time (this time it's for Linux and Mac, previous
323          similar fix was for Windows)
324        - thread safety fixes for the instrument loading thread
325        - LV2: use the new lv2 package if present
326        - VST: try to open Fantasia automatically on Linux and Mac too (on
327          Linux, the Fantasia jar should be placed in <prefix>/share/java)
328        - VST: fixed crashes on Linux Ardour and EnergyXT
329        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
330          port and audio channel routing for DSSI plugins are now visible.

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

520          (labelled "Disk stream not available in time")
521        - Update effects on sample rate & period size changes (to avoid
522          crashes and noise on such transitions).
523        - ignore missing LADSPA paths without ignoring valid LADSPA paths
524          (fixes #208)
525        - Fixed bug in LSCP grammar definition which caused a statement like
526          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
527          practically irrelevant, however it caused problems with the new LSCP
528          shell's auto completion feature).
529        - Fixed MIDI program change messages being ignored if quickly executed
530          after each other (fixes #231).

671          connected to the respective MIDI input port the SysEx message arrived
672          on)
673        - bugfix: notes triggered at position 0 in the audio buffer were
674          sometimes wrongly killed in the same buffer, causing no sound to
675          be played
676        - added support for chromatic / drumkit mode Roland GS Sysex message
677          which is usally used to switch a part between chromatic sounds and
678          drumkit sounds (as opposed to their common default setting of MIDI
679          part 10 being a drumkit part and all other ones chromatic parts), in
680          LS however one can switch between the first 16 MIDI instrument maps
681          defined for the sampler

711        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
712          SET DB_INSTRUMENT FILE_PATH
713        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
714          frontends to send MIDI messages to specific sampler channel
715        - added two additional fields to GET FILE INSTRUMENT INFO command -
716          KEY_BINDINGS and KEYSWITCH_BINDINGS
717        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
718          was incorrect
719        - Optimized the retrieval of the MIDI instrument mappings
720        - added new LSCP command "SET VOICES" to globally alter the maximum
721          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
722          be triggered respectively
723        - added new LSCP command "SET STREAMS" to globally alter the maximum

733      * Bug fixes:
734        - fixed a crash which occurs when removing a sampler channel waiting
735          to start instrument loading after another channel
736        - fixed a crash which occurs when removing a sampler channel with
737          instrument loading in progress (bug #113)
738        - fixed termination caused by uncaught exception when adding MIDI
739          instrument with PERSISTENT load mode
740        - fixed possible iterator invalidations when resetting the sampler
741        - fixed memory leaks when issuing the following LSCP commands:
742          GET AUDIO_OUTPUT_DRIVER INFO
743          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
744          GET MIDI_INPUT_DRIVER INFO
745          GET MIDI_INPUT_DRIVER_PARAMETER INFO
746        - fixed possible compilation error when sqlite is not present
747        - fixed orphaned pointers when setting maximum voices limit (bug #118)
748        - fixed crash when changing the audio output device of a sampler
749          channel with loaded instrument and start playing notes
750        - fixed endless loop in Engine::SuspendAll() (bug #120)
751        - fixed a low-level atomic load function that was broken on 64-bit
752          PowerPC, which probably could cause crashes on that platform
753        - fixed a memory management error which could cause a crash when a
754          plugin was unloaded
755        - bugfix: two private structs had the same name, which could cause
756          problems if the linker chose the wrong constructor
757        - fixed low-level ConditionServer usage bug that caused lockups on
758          Windows
