# 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        - Implemented built-in script variable "$KSP_TIMER".
80        - Implemented built-in script variable "$NKSP_REAL_TIMER".
81        - Implemented built-in script variable "$NKSP_PERF_TIMER".
82        - Implemented built-in script variable "$ENGINE_UPTIME".
83        - Implemented built-in script function "inc()".
84        - Implemented built-in script function "dec()".
85        - NKSP language fix: division expressions were evaluated too often.
86        - NKSP language fix: string concatenation operator was right
87          associative instead of left (to right).
88        - NKSP language correction: allow empty statements in entire language
89          (i.e. "if end if").
90

93      * packaging changes:
94        - fixed building with newer MinGW-w64
95        - Mac OS X: support the new dir for Core Audio SDK
96        - Mac OS X: fixed building outside source directory

99        - removed empty directories left from the cvs to svn migration
100        - fixed compilation with gcc 4.6.1
101        - another "make dist" fix, for the LV2 plugin
102        - made --enable-pthread-testcancel default on Mac OS X
103        - minor Makefile fix for building lscpparser when build and source
104          directories are separate
105        - Mac OS X: made it possible to specify plugin installation dir to
106          configure
107        - Mac OS X: Makefile fix for the install-strip target
108        - fixed compilation with gcc 4.7

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

206          key
207        - bugfix: pitch LFO controller "internal+aftertouch" was broken
208        - bugfix: filter keyboard tracking was broken
209        - filter performance fix (an unnecessary copy was made of the
210          filter parameters in each sub fragment)
211        - handle special case when pan parameter in gig file has max or
212          min value
213        - Exclusive Groups: don't ever stop voices of the same note,
214          doesn't sound naturally with a drumkit
215        - fixed EG1 modulation when attack or release is zero
216        - Fixed support for 'aftertouch' attenuation controller.

239        - fine-tuned the default velocity curve
240        - added support for transpose
241        - fixed crash when using sw_down/up
242        - improved logic for sw_lokey/hikey/up/down/last
243        - added more v1 aliases to parser
244        - reduced memory usage for sfz data

368          used
369        - bugfix: looping was disabled if loop_start was set to 0
370        - allow regions with end=-1 to turn off other regions using the
371          group and off_by opcodes (#168)

380          (modified patch which was originally posted by Sergey on LS mailing list)
381        - bugfix: generation of velocity curves etc should not be done
382          after each "#include", only after the main file is parsed
383        - bugfix: line numbers in error messages were wrong after "#include"
384        - added support for float and 32 bit sample files
385    
386      * SoundFont format engine:
387        - Initial implementation (not usable yet)
388        - RT-safeness: avoid malloc in audio thread
389        - fixed a bug that could cause voice stealing to fail

393        - use linear decay and release for filter and pitch EG
394    
395      * Host plugins (VST, AU, LV2, DSSI):
396        - AU bugfix: failed to destroy its audio/MIDI devices
397        - Listen to all interfaces on Mac OS X (INADDR_ANY)
398        - VST bugfix: If the host called resume() before and after
399          changing sample rate or block size, the number of channels was
400          incorrectly set to two. This caused silence in Cubase 5.
401        - save engine type (gig, sfz or sf2) in plugin state
402        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
403          64 bit Windows
404        - AU: changed number of output channels from one stereo to 16
405          stereo

415        - thread safety fixes for the instrument loading thread
416        - LV2: use the new lv2 package if present
417        - VST: try to open Fantasia automatically on Linux and Mac too (on
418          Linux, the Fantasia jar should be placed in <prefix>/share/java)
419        - VST: fixed crashes on Linux Ardour and EnergyXT
420        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
421          port and audio channel routing for DSSI plugins are now visible.
422        - LV2: use urid and atom extensions instead of deprecated uri-map
423          and event
424        - LV2: lv2 package 1.0 is now required to build the LV2 plugin

430          sampler's internal MIDI instrument mapping system
431    
432      * Instrument editor interface:
433        - Changed instrument editor plugin interface, providing additional
434          informations like the EngineChannel for which the instrument editor was
435          spawned for. This allows the instrument editors to interact more actively
436          with the sampler.
437    
438      * MIDI driver:
439        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
440          the ALSA sequencer client name
441        - removed limit of maximum amount of MIDI ports per MIDI device, since
442          there is no reason for this limit
443        - MME: fixed memory handling bug found with cppcheck
444        - MME: removed compiler warning
445        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
446          which allows to retrieve the list of CoreMIDI clients / ports and to connect
447          to them a la JACK, via the usual sampler APIs
448        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
449          the driver will automatically connect to other CoreMIDI clients' ports

451        - added support for MIDI note on velocity filter
452        - CoreMIDI: fixed memory deallocation error
453        - Fixed variable underflow in VirtualMidiDevice, which caused graphical
454          virtual keyboards in frontends / instrument editors being stuck.
455        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
456        - Implemented missing handling of MIDI "running status".
457        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
458        - MME bugfix: driver wasn't closed properly
459        - CoreMIDI: automatically connect to all input sources by default (driver
460          parameter "AUTO_BIND").
461        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
462        - CoreMIDI: fixed minor memory leak
463    
464      * audio driver:
465        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
466        - JACK audio: react on sample rate changes.
467        - JACK audio: react on buffer size changes.

469          RT context.
470        - ASIO driver: removed compiler warnings
471        - CoreAudio: fixed minor error handling bug
472        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)
473        - JACK audio: return the JACK server's current sample rate as default value
474          for audio device parameter "SAMPLERATE" (fixes #166).
475

524        - Added support for built-in LSCP reference documentation, which will
525          automatically show the relevant LSCP reference section on screen as soon
526          as one specific LSCP command was detected while typing on the command

587        - bugfix: calling SET VOICES (which Fantasia does on start and
588          refresh) could cause instruments to be unloaded
589        - Mac OS X: fixed name collision of enum in EffectControl and
590          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
591        - Mac OS X: fixed hanging threads

593          it caused hanging threads on Windows
594        - Fixed possible crashes due to corrupted MIDI/audio device list
595          after MIDI/audio device creation failure
596        - When creating MIDI instrument map entries with "PERSISTENT" type, the
597          instruments were uselessly precached with zero samples, however it still
598          took the full preloading time and on 1st program change the respective
599          instrument was completely reloaded again.
600        - fixed handling of rapid bank select and program change messages
601          sent to the same sampler channel (patch from the Open Octave
602          project, slightly adjusted)

613        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
614        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
615          introduced in previous fix)
616        - fixed crash when a channel received a program change while
617          playing a note in a key group
618        - fixed erroneous error message piping in VoiceBase.h
619          (labelled "Disk stream not available in time")
620        - Update effects on sample rate & period size changes (to avoid
621          crashes and noise on such transitions).
622        - ignore missing LADSPA paths without ignoring valid LADSPA paths
623          (fixes #208)
624        - Fixed bug in LSCP grammar definition which caused a statement like
625          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
626          practically irrelevant, however it caused problems with the new LSCP
627          shell's auto completion feature).
628        - Fixed MIDI program change messages being ignored if quickly executed
629          after each other (fixes #231).

747        - work-around for missing fnmatch function on Windows to make
748          instrument database compilable
749        - added instrument database support on Windows
750          works with both standalone mode and VST plugin.
751          the instruments DB file is located in
752          %USERPROFILE%\.linuxsampler\instruments.db which allows different
753          databases for each windows user
754          if no DB is present it automatically creates the .linuxsampler subdir
755          and then creates an empty DB
756        - fixed recursive import, which was broken on Windows

784        - bugfix: on sample reference changes (instrument editor), only
785          un-cache the respective sample if it's really not used by any
786          sampler engine anymore
787        - re-cache samples in case they were changed by an instrument editor,
788          e.g. when a sample was added while playing (#82)
789        - fixed hanging notes which occured when note-off event had the exact
790          same time stamp as the voice's note-on event and occured both in the
791          same audio fragment cycle (fixes bug #112)
792        - added support for the "fine tune" and "pitch bend range"
