# 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    
77    Version 2.0.0 (15 July 2015)
78

80        - fixed building with newer MinGW-w64
81        - Mac OS X: support the new dir for Core Audio SDK
82        - Mac OS X: fixed building outside source directory
83        - made sure all source files for hostplugins are included when
84          doing "make dist"
85        - removed empty directories left from the cvs to svn migration
86        - fixed compilation with gcc 4.6.1
87        - another "make dist" fix, for the LV2 plugin
88        - made --enable-pthread-testcancel default on Mac OS X
89        - minor Makefile fix for building lscpparser when build and source
90          directories are separate
91        - Mac OS X: made it possible to specify plugin installation dir to
92          configure
93        - Mac OS X: Makefile fix for the install-strip target
94        - fixed compilation with gcc 4.7
95        - fixed configure script error with old autoconf versions
96        - lsatomic.h: use gcc provided atomic functions if building with
97          gcc 4.7 and C++11
98        - modernized configure script
99        - fixed linkage error when building with
100          LDFLAGS="-Wl,--no-undefined" (#190)
101        - fixed compilation with Clang 3.2

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

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

354          used
355        - bugfix: looping was disabled if loop_start was set to 0
356        - allow regions with end=-1 to turn off other regions using the

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

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

409          and event
410        - LV2: lv2 package 1.0 is now required to build the LV2 plugin

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

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

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

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

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

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

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

734          instrument database compilable
735        - added instrument database support on Windows
736          works with both standalone mode and VST plugin.
737          the instruments DB file is located in
738          %USERPROFILE%\.linuxsampler\instruments.db which allows different
