# 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        - Implemented built-in script function "stop_wait()".
91        - Implemented built-in script variable "$NI_CALLBACK_ID".
92        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
93        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
94        - Added support for read-only built-in variables (respectively
95          handled by the script parser).
96        - Added built-in script constant "$NI_CB_TYPE_INIT".
97        - Added built-in script constant "$NI_CB_TYPE_NOTE".
98        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
99        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".

109        - removed empty directories left from the cvs to svn migration
110        - fixed compilation with gcc 4.6.1
111        - another "make dist" fix, for the LV2 plugin
112        - made --enable-pthread-testcancel default on Mac OS X
113        - minor Makefile fix for building lscpparser when build and source
114          directories are separate
115        - Mac OS X: made it possible to specify plugin installation dir to

117        - Mac OS X: Makefile fix for the install-strip target
118        - fixed compilation with gcc 4.7
119        - fixed configure script error with old autoconf versions

134        - fixed build error on newer MinGW
135        - support building with older jack versions
136        - support building with spaces in vst sdk path
137        - enabled automake 'subdir-objects' option and moved external
138          source references (vst, au, asio) from makefiles to cpp files,
139          in order to get rid of warnings from automake 1.14
140    
141      * general changes:
142        - Refactoring: moved the independent code from
143          the Gigasampler format engine to base classes
144        - command line option '--profile' is currently disabled, since the
145          respective profiling code is currently broken
146        - Introduced support for optional environment variable
147          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
148          where the sampler shall look for instrument editor plugins
149          (patch by Luis Garrido, slightly modified).
150        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
151        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
152        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
153          note (in this implementation of the sampler its simply hard routed to
154          the 1st effect send of the sampler channel, no matter what the actual
155          effect type is)
156        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
157          note (in this implementation of the sampler its simply hard routed to
158          the 2nd effect send of the sampler channel, no matter what the actual
159          effect type is)
160        - implemented support for internal LADSPA effects
161        - raised limit of program change queue from 100 to 512
162          (as suggested by Alex Stone)
163        - implemented sine LFO, pulse LFO and saw LFO
164        - experimental support for per voice equalization
165        - added command line option --exec-after-init
166        - Introduced new C++ API method:
167          EngineChannel::InstrumentFileName(int index)
168          allowing to retrieve the whole list of files used for the loaded
169          instrument on an engine channel (a.k.a. part). Some GigaStudio
170          instruments for example are splitted over several files like
171          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
172        - Added new C++ API method Sampler::GetGlobalMaxVoices().
173        - Added new C++ API method Sampler::GetGlobalMaxStreams().
174        - Added new C++ API method Sampler::SetGlobalMaxVoices().
175        - Added new C++ API method Sampler::SetGlobalMaxStreams().
176        - Various "const" and "restrict" optimizations.
177        - all engines: add pan CC value to instrument pan parameter before
178          applying panning, instead of using two separate pan functions in
179          series (#182)
180        - added a lock guard class for exception safe mutex handling and
181          used it everywhere appropriate
182        - Immediately apply scale tuning changes to active voices.
183        - Exposed scale tuning to C++ API (along to the already existing standard
184          SysEx way).
185        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
186          and broken for ppc64. (Seq_cst loads and stores are actually not
187          used in LS, so the bug wasn't noticable.)
188        - lsatomic.h: added ARMv7 support
189        - Added support for multiple MIDI input ports per sampler channel (and
190          added various new C++ methods for this new feature / design change, old
191          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
192          as deprecated but are still there and should provide full behavior
193          backward compatibility).
194        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
195          unsafe and caused compilation error with clang 2.x).
196        - Bugfix: only process the latest MIDI program change event.
197        - Introducing the LSCP shell, which provides convenient control of the
198          sampler from the command line by providing LSCP aware features.
199        - VirtualMidiDevice: Added support for program change.
200        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
201        - VirtualMidiDevice: Added support for pitch bend.
202        - Aftertouch: extended API to explicitly handle channel pressure and
203          polyphonic key pressure events (so far polyphonic pressure was not
204          supported at all, and channel pressure was rerouted as CC128 but not
205          used so far).
206        - Added initial support for real-time instrument scripts. The script VM
207          code is shared by all sampler engine implemementations, however only the
208          gig file format currently provides support for storing instrument scripts
209          (as LinuxSampler extension to the original GigaStudio 4 format).
210    
211      * Gigasampler format engine:
212        - implemented the "round robin keyboard" dimension
213        - fixed round robin and random dimensions for cases when number of
214          dimension zones is not a power of two
215        - made round robin use a counter for each region instead of each
216          key
217        - bugfix: pitch LFO controller "internal+aftertouch" was broken
218        - bugfix: filter keyboard tracking was broken
219        - filter performance fix (an unnecessary copy was made of the
220          filter parameters in each sub fragment)
221        - handle special case when pan parameter in gig file has max or
222          min value
223        - Exclusive Groups: don't ever stop voices of the same note,
224          doesn't sound naturally with a drumkit
225        - fixed EG1 modulation when attack or release is zero
226        - Fixed support for 'aftertouch' attenuation controller.
227        - Fixed crash that happened with velocity split sounds under certain
228          conditions (see also previous commit on libgig).

249        - fine-tuned the default velocity curve
250        - added support for transpose
251        - fixed crash when using sw_down/up
252        - improved logic for sw_lokey/hikey/up/down/last
253        - added more v1 aliases to parser
254        - reduced memory usage for sfz data
255        - RT-safeness: avoid malloc in audio thread
256        - fixed a bug that could cause voice stealing to fail

406        - AU bugfix: failed to destroy its audio/MIDI devices
407        - Listen to all interfaces on Mac OS X (INADDR_ANY)
408        - VST bugfix: If the host called resume() before and after
409          changing sample rate or block size, the number of channels was
410          incorrectly set to two. This caused silence in Cubase 5.
411        - save engine type (gig, sfz or sf2) in plugin state
412        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
413          64 bit Windows
414        - AU: changed number of output channels from one stereo to 16
415          stereo

429        - VST: fixed crashes on Linux Ardour and EnergyXT
430        - DSSI bugfix: it wasn't possible to change engine type. The MIDI

444          informations like the EngineChannel for which the instrument editor was
445          spawned for. This allows the instrument editors to interact more actively
446          with the sampler.
447    
448      * MIDI driver:
449        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
450          the ALSA sequencer client name

452          there is no reason for this limit
453        - MME: fixed memory handling bug found with cppcheck
454        - MME: removed compiler warning
455        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
456          which allows to retrieve the list of CoreMIDI clients / ports and to connect
457          to them a la JACK, via the usual sampler APIs
458        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled

466        - Implemented missing handling of MIDI "running status".
467        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
468        - MME bugfix: driver wasn't closed properly
469        - CoreMIDI: automatically connect to all input sources by default (driver
470          parameter "AUTO_BIND").
471        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
472        - CoreMIDI: fixed minor memory leak
473    
474      * audio driver:

479          RT context.
480        - ASIO driver: removed compiler warnings
481        - CoreAudio: fixed minor error handling bug
482        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)

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

625          introduced in previous fix)
626        - fixed crash when a channel received a program change while
627          playing a note in a key group
628        - fixed erroneous error message piping in VoiceBase.h
629          (labelled "Disk stream not available in time")

631          crashes and noise on such transitions).
632        - ignore missing LADSPA paths without ignoring valid LADSPA paths
633          (fixes #208)
634        - Fixed bug in LSCP grammar definition which caused a statement like
635          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
636          practically irrelevant, however it caused problems with the new LSCP
637          shell's auto completion feature).
638        - Fixed MIDI program change messages being ignored if quickly executed
639          after each other (fixes #231).

714        - Makefile fix: JACK_CFLAGS wasn't used
715        - JACK: use jack_client_open instead of the deprecated
716          jack_client_new
717        - added (experimental) CoreAudio driver
718        - applied old fixes to the ASIO driver that were included in the
719          previous binary release but accidentally never committed to CVS
720          (fixes #117)
721        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
722          win64)
723        - VST: added support for sample rate and buffer size changes
724        - VST: close editor (Fantasia) when the VST is removed
725        - VST: avoid opening Fantasia more than once for each VST instance
726        - VST: export main function as "main" on Linux too (fix for
727          energyXT)
728        - VST: changed number of output channels from one stereo to 16
729          stereo
730        - added channel routing, fxsends and midi maps to the settings
731          stored in the plugin state
732        - performance optimization of AudioChannel::MixTo() and
733          AudioChannel::CopyTo() methods using GCC vector exensions
734          (if available)
735        - ASIO fixes: avoid initializing the device twice, avoid throwing

738    * MIDI driver:    * MIDI driver:
739      - added JACK MIDI driver      - added JACK MIDI driver
740        - dispatch bank select as ordinary CC as well, the user might seriously
741          want to (mis)use it for some purpose ("fixed" in all current MIDI
742          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
743        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
744          CoreMidi or AU
745        - fixed mingw-w64 compilation error in MME driver
746        - made program change handling in MIDI thread real-time safe by
747          moving the logic to a non-RT thread

753        - added support for handling lost files in the instruments database
754        - Implemented option for adding instruments in separate directories
755          in the instruments database
756          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
757        - work-around for missing fnmatch function on Windows to make
758          instrument database compilable
759        - added instrument database support on Windows
760          works with both standalone mode and VST plugin.
761          the instruments DB file is located in
762          %USERPROFILE%\.linuxsampler\instruments.db which allows different
763          databases for each windows user
764          if no DB is present it automatically creates the .linuxsampler subdir
765          and then creates an empty DB
766        - fixed recursive import, which was broken on Windows
767    
768    * Gigasampler format engine:    * Gigasampler format engine:

772        isn't running        isn't running
773        - added partial support for the "Controller Triggered" MIDI rule,
774          enough for piano gigs with pedal noise samples
775        - minor fix: only mark FX sends as being modified if really the
776          respective FX send MIDI controller was used
777        - added support for GM global device volume SysEx message
778          (can be selected at compile time to either apply globally to the
779          whole sampler [default] or only to the sampler channels that are
780          connected to the respective MIDI input port the SysEx message arrived
781          on)
782        - bugfix: notes triggered at position 0 in the audio buffer were
783          sometimes wrongly killed in the same buffer, causing no sound to
784          be played
785        - added support for chromatic / drumkit mode Roland GS Sysex message
786          which is usally used to switch a part between chromatic sounds and
787          drumkit sounds (as opposed to their common default setting of MIDI
788          part 10 being a drumkit part and all other ones chromatic parts), in
789          LS however one can switch between the first 16 MIDI instrument maps
790          defined for the sampler
791        - made it possible to create multiple sample channels even if the
792          audio thread isn't running
793        - fixed crash when removing channel with active voices (#116)
794        - bugfix: on sample reference changes (instrument editor), only
795          un-cache the respective sample if it's really not used by any
796          sampler engine anymore
797        - re-cache samples in case they were changed by an instrument editor,
798          e.g. when a sample was added while playing (#82)
799        - fixed hanging notes which occured when note-off event had the exact
800          same time stamp as the voice's note-on event and occured both in the
801          same audio fragment cycle (fixes bug #112)
802        - added support for the "fine tune" and "pitch bend range"
803          instrument-level gig parameters
804        - fixed minor artifacts in pitch bend handling
805        - added support for GS Reset SysEx message
806        - allow gig files to use unlimited downward pitch shifting
807        - added a limit check for upward pitch shifting
808        - bugfix: sometimes, when playing a note twice fast, the second
809          note was silent
810        - fixed crash happening when a pitch bend event arrived at the
811          same time a new instrument was loading
812    
813    * LSCP server:    * LSCP server:
814      - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to      - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to

817      - added new LSCP event "DEVICE_MIDI" which can be used by frontends to      - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
818        react on MIDI data arriving on certain MIDI input devices (so far only        react on MIDI data arriving on certain MIDI input devices (so far only
819        Note-On and Note-Off events are sent via this LSCP event)        Note-On and Note-Off events are sent via this LSCP event)
820        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
821          SET DB_INSTRUMENT FILE_PATH
822        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
823          frontends to send MIDI messages to specific sampler channel
824        - added two additional fields to GET FILE INSTRUMENT INFO command -
825          KEY_BINDINGS and KEYSWITCH_BINDINGS
826        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
827          was incorrect
828        - Optimized the retrieval of the MIDI instrument mappings
829        - added new LSCP command "SET VOICES" to globally alter the maximum
830          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
831          be triggered respectively
832        - added new LSCP command "SET STREAMS" to globally alter the maximum
833          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
834          which will be triggered respectively
835        - bugfix: retry if "select" returns EINTR (this fixes a crash when
836          a gigedit file dialog is opened)
837        - close all connections when LSCPServer is deleted
838        - hard close of all sockets on exit
839        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
840          driver
841    
842      * Bug fixes:
843        - fixed a crash which occurs when removing a sampler channel waiting
844          to start instrument loading after another channel
845        - fixed a crash which occurs when removing a sampler channel with
846          instrument loading in progress (bug #113)
847        - fixed termination caused by uncaught exception when adding MIDI
848          instrument with PERSISTENT load mode
849        - fixed possible iterator invalidations when resetting the sampler
850        - fixed memory leaks when issuing the following LSCP commands:
851          GET AUDIO_OUTPUT_DRIVER INFO
852          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
853          GET MIDI_INPUT_DRIVER INFO
854          GET MIDI_INPUT_DRIVER_PARAMETER INFO
855        - fixed possible compilation error when sqlite is not present
856        - fixed orphaned pointers when setting maximum voices limit (bug #118)
857        - fixed crash when changing the audio output device of a sampler
858          channel with loaded instrument and start playing notes
859        - fixed endless loop in Engine::SuspendAll() (bug #120)
860        - fixed a low-level atomic load function that was broken on 64-bit
861          PowerPC, which probably could cause crashes on that platform
862        - fixed a memory management error which could cause a crash when a
863          plugin was unloaded
864        - bugfix: two private structs had the same name, which could cause
865          problems if the linker chose the wrong constructor
866        - fixed low-level ConditionServer usage bug that caused lockups on
867          Windows
