# 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

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

116          on the process's main thread
117        - fixed build error on newer MinGW
118        - support building with older jack versions
119        - support building with spaces in vst sdk path
120        - enabled automake 'subdir-objects' option and moved external
121          source references (vst, au, asio) from makefiles to cpp files,
122          in order to get rid of warnings from automake 1.14
123    
124      * general changes:
125        - Refactoring: moved the independent code from
126          the Gigasampler format engine to base classes
127        - command line option '--profile' is currently disabled, since the
128          respective profiling code is currently broken
129        - Introduced support for optional environment variable
130          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
131          where the sampler shall look for instrument editor plugins
132          (patch by Luis Garrido, slightly modified).
133        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
134        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
135        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
136          note (in this implementation of the sampler its simply hard routed to
137          the 1st effect send of the sampler channel, no matter what the actual
138          effect type is)
139        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
140          note (in this implementation of the sampler its simply hard routed to
141          the 2nd effect send of the sampler channel, no matter what the actual
142          effect type is)
143        - implemented support for internal LADSPA effects
144        - raised limit of program change queue from 100 to 512
145          (as suggested by Alex Stone)
146        - implemented sine LFO, pulse LFO and saw LFO
147        - experimental support for per voice equalization
148        - added command line option --exec-after-init
149        - Introduced new C++ API method:
150          EngineChannel::InstrumentFileName(int index)
151          allowing to retrieve the whole list of files used for the loaded
152          instrument on an engine channel (a.k.a. part). Some GigaStudio
153          instruments for example are splitted over several files like
154          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
155        - Added new C++ API method Sampler::GetGlobalMaxVoices().
156        - Added new C++ API method Sampler::GetGlobalMaxStreams().
157        - Added new C++ API method Sampler::SetGlobalMaxVoices().
158        - Added new C++ API method Sampler::SetGlobalMaxStreams().
159        - Various "const" and "restrict" optimizations.
160        - all engines: add pan CC value to instrument pan parameter before
161          applying panning, instead of using two separate pan functions in
162          series (#182)
163        - added a lock guard class for exception safe mutex handling and
164          used it everywhere appropriate
165        - Immediately apply scale tuning changes to active voices.
166        - Exposed scale tuning to C++ API (along to the already existing standard
167          SysEx way).
168        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
169          and broken for ppc64. (Seq_cst loads and stores are actually not
170          used in LS, so the bug wasn't noticable.)
171        - lsatomic.h: added ARMv7 support
172        - Added support for multiple MIDI input ports per sampler channel (and
173          added various new C++ methods for this new feature / design change, old
174          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
175          as deprecated but are still there and should provide full behavior
176          backward compatibility).
177        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
178          unsafe and caused compilation error with clang 2.x).
179        - Bugfix: only process the latest MIDI program change event.
180        - Introducing the LSCP shell, which provides convenient control of the
181          sampler from the command line by providing LSCP aware features.
182        - VirtualMidiDevice: Added support for program change.
183        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
184        - VirtualMidiDevice: Added support for pitch bend.
185        - Aftertouch: extended API to explicitly handle channel pressure and
186          polyphonic key pressure events (so far polyphonic pressure was not
187          supported at all, and channel pressure was rerouted as CC128 but not
188          used so far).
189        - Added initial support for real-time instrument scripts. The script VM
190          code is shared by all sampler engine implemementations, however only the
191          gig file format currently provides support for storing instrument scripts
192          (as LinuxSampler extension to the original GigaStudio 4 format).
193    
194      * Gigasampler format engine:
195        - implemented the "round robin keyboard" dimension
196        - fixed round robin and random dimensions for cases when number of
197          dimension zones is not a power of two
198        - made round robin use a counter for each region instead of each
199          key
200        - bugfix: pitch LFO controller "internal+aftertouch" was broken
201        - bugfix: filter keyboard tracking was broken
202        - filter performance fix (an unnecessary copy was made of the
203          filter parameters in each sub fragment)
204        - handle special case when pan parameter in gig file has max or
205          min value
206        - Exclusive Groups: don't ever stop voices of the same note,
207          doesn't sound naturally with a drumkit
208        - fixed EG1 modulation when attack or release is zero
209        - Fixed support for 'aftertouch' attenuation controller.
210        - Fixed crash that happened with velocity split sounds under certain
211          conditions (see also previous commit on libgig).
212        - fixed behaviour of filter LFO
213    
214      * SFZ format engine:
215        - Initial implementation (not usable yet)

217        - added a fine-tuned v1 envelope generator instead of using the
218          one from the gig engine

220        - added support for trigger=first, trigger=legato and sw_previous
221        - allow non-numerical key values ("C#4" for example)
222        - "key" opcode now sets pitch_keycenter too
223        - fixed error when unloading instrument with same sample used by
224          multiple regions

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

361          used
362        - bugfix: looping was disabled if loop_start was set to 0
363        - allow regions with end=-1 to turn off other regions using the

389        - AU bugfix: failed to destroy its audio/MIDI devices
390        - Listen to all interfaces on Mac OS X (INADDR_ANY)
391        - VST bugfix: If the host called resume() before and after
392          changing sample rate or block size, the number of channels was
393          incorrectly set to two. This caused silence in Cubase 5.
394        - save engine type (gig, sfz or sf2) in plugin state
395        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
396          64 bit Windows
397        - AU: changed number of output channels from one stereo to 16
398          stereo

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

426        - Changed instrument editor plugin interface, providing additional
427          informations like the EngineChannel for which the instrument editor was
428          spawned for. This allows the instrument editors to interact more actively
429          with the sampler.
430    
431      * MIDI driver:
432        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
433          the ALSA sequencer client name

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

449        - Implemented missing handling of MIDI "running status".
450        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
451        - MME bugfix: driver wasn't closed properly
452        - CoreMIDI: automatically connect to all input sources by default (driver
453          parameter "AUTO_BIND").
454        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
455        - CoreMIDI: fixed minor memory leak
456    
457      * audio driver:
458        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
459        - JACK audio: react on sample rate changes.

462          RT context.
463        - ASIO driver: removed compiler warnings
464        - CoreAudio: fixed minor error handling bug
465        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)

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

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