# 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".
100        - NKSP Language: Added support for user defined script functions.
101        - Implemented built-in script function "change_attack()".
102        - Implemented built-in script function "change_decay()".
103        - Implemented built-in script function "change_release()".

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

121        - Mac OS X: Makefile fix for the install-strip target
122        - fixed compilation with gcc 4.7

138        - fixed build error on newer MinGW
139        - support building with older jack versions
140        - support building with spaces in vst sdk path
141        - enabled automake 'subdir-objects' option and moved external
142          source references (vst, au, asio) from makefiles to cpp files,
143          in order to get rid of warnings from automake 1.14
144    
145      * general changes:
146        - Refactoring: moved the independent code from
147          the Gigasampler format engine to base classes
148        - command line option '--profile' is currently disabled, since the
149          respective profiling code is currently broken
150        - Introduced support for optional environment variable
151          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
152          where the sampler shall look for instrument editor plugins
153          (patch by Luis Garrido, slightly modified).
154        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
155        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
156        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
157          note (in this implementation of the sampler its simply hard routed to
158          the 1st effect send of the sampler channel, no matter what the actual
159          effect type is)
160        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
161          note (in this implementation of the sampler its simply hard routed to
162          the 2nd effect send of the sampler channel, no matter what the actual
163          effect type is)
164        - implemented support for internal LADSPA effects
165        - raised limit of program change queue from 100 to 512
166          (as suggested by Alex Stone)

168        - experimental support for per voice equalization
169        - added command line option --exec-after-init
170        - Introduced new C++ API method:
171          EngineChannel::InstrumentFileName(int index)
172          allowing to retrieve the whole list of files used for the loaded
173          instrument on an engine channel (a.k.a. part). Some GigaStudio
174          instruments for example are splitted over several files like
175          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
176        - Added new C++ API method Sampler::GetGlobalMaxVoices().
177        - Added new C++ API method Sampler::GetGlobalMaxStreams().
178        - Added new C++ API method Sampler::SetGlobalMaxVoices().
179        - Added new C++ API method Sampler::SetGlobalMaxStreams().
180        - Various "const" and "restrict" optimizations.
181        - all engines: add pan CC value to instrument pan parameter before
182          applying panning, instead of using two separate pan functions in
183          series (#182)
184        - added a lock guard class for exception safe mutex handling and
185          used it everywhere appropriate
186        - Immediately apply scale tuning changes to active voices.
187        - Exposed scale tuning to C++ API (along to the already existing standard
188          SysEx way).
189        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
190          and broken for ppc64. (Seq_cst loads and stores are actually not
191          used in LS, so the bug wasn't noticable.)
192        - lsatomic.h: added ARMv7 support
193        - Added support for multiple MIDI input ports per sampler channel (and
194          added various new C++ methods for this new feature / design change, old
195          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
196          as deprecated but are still there and should provide full behavior
197          backward compatibility).
198        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
199          unsafe and caused compilation error with clang 2.x).
200        - Bugfix: only process the latest MIDI program change event.
201        - Introducing the LSCP shell, which provides convenient control of the
202          sampler from the command line by providing LSCP aware features.
203        - VirtualMidiDevice: Added support for program change.
204        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
205        - VirtualMidiDevice: Added support for pitch bend.
206        - Aftertouch: extended API to explicitly handle channel pressure and
207          polyphonic key pressure events (so far polyphonic pressure was not
208          supported at all, and channel pressure was rerouted as CC128 but not
209          used so far).
210        - Added initial support for real-time instrument scripts. The script VM
211          code is shared by all sampler engine implemementations, however only the
212          gig file format currently provides support for storing instrument scripts
213          (as LinuxSampler extension to the original GigaStudio 4 format).
214    
215      * Gigasampler format engine:
216        - implemented the "round robin keyboard" dimension
217        - fixed round robin and random dimensions for cases when number of
218          dimension zones is not a power of two
219        - made round robin use a counter for each region instead of each
220          key
221        - bugfix: pitch LFO controller "internal+aftertouch" was broken
222        - bugfix: filter keyboard tracking was broken
223        - filter performance fix (an unnecessary copy was made of the
224          filter parameters in each sub fragment)
225        - handle special case when pan parameter in gig file has max or
226          min value
227        - Exclusive Groups: don't ever stop voices of the same note,
228          doesn't sound naturally with a drumkit
229        - fixed EG1 modulation when attack or release is zero
230        - Fixed support for 'aftertouch' attenuation controller.
231        - Fixed crash that happened with velocity split sounds under certain
232          conditions (see also previous commit on libgig).

253        - fine-tuned the default velocity curve
254        - added support for transpose
255        - fixed crash when using sw_down/up
256        - improved logic for sw_lokey/hikey/up/down/last
257        - added more v1 aliases to parser
258        - reduced memory usage for sfz data
259        - RT-safeness: avoid malloc in audio thread
260        - fixed a bug that could cause voice stealing to fail
261        - optimized sample lookup
262        - improved support for exclusive groups (group, off_by and

276          (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
277          ampeg_vel2release)
278        - added support for EG hold (ampeg_hold)

382          used
383        - bugfix: looping was disabled if loop_start was set to 0
384        - allow regions with end=-1 to turn off other regions using the

410        - AU bugfix: failed to destroy its audio/MIDI devices
411        - Listen to all interfaces on Mac OS X (INADDR_ANY)
412        - VST bugfix: If the host called resume() before and after
413          changing sample rate or block size, the number of channels was
414          incorrectly set to two. This caused silence in Cubase 5.
415        - save engine type (gig, sfz or sf2) in plugin state
416        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
417          64 bit Windows
418        - AU: changed number of output channels from one stereo to 16
419          stereo

429        - thread safety fixes for the instrument loading thread
430        - LV2: use the new lv2 package if present
431        - VST: try to open Fantasia automatically on Linux and Mac too (on
432          Linux, the Fantasia jar should be placed in <prefix>/share/java)
433        - VST: fixed crashes on Linux Ardour and EnergyXT
434        - DSSI bugfix: it wasn't possible to change engine type. The MIDI

447        - Changed instrument editor plugin interface, providing additional
448          informations like the EngineChannel for which the instrument editor was
449          spawned for. This allows the instrument editors to interact more actively
450          with the sampler.
451    
452      * MIDI driver:
453        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
454          the ALSA sequencer client name

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

470        - Implemented missing handling of MIDI "running status".
471        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
472        - MME bugfix: driver wasn't closed properly
473        - CoreMIDI: automatically connect to all input sources by default (driver
474          parameter "AUTO_BIND").
475        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
476        - CoreMIDI: fixed minor memory leak
477    
478      * audio driver:
479        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
480        - JACK audio: react on sample rate changes.

483          RT context.
484        - ASIO driver: removed compiler warnings
485        - CoreAudio: fixed minor error handling bug
486        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)

604          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
605        - Mac OS X: fixed hanging threads

608        - Fixed possible crashes due to corrupted MIDI/audio device list
609          after MIDI/audio device creation failure
610        - When creating MIDI instrument map entries with "PERSISTENT" type, the
611          instruments were uselessly precached with zero samples, however it still
612          took the full preloading time and on 1st program change the respective
613          instrument was completely reloaded again.
614        - fixed handling of rapid bank select and program change messages
615          sent to the same sampler channel (patch from the Open Octave
616          project, slightly adjusted)

629          introduced in previous fix)
630        - fixed crash when a channel received a program change while
631          playing a note in a key group
632        - fixed erroneous error message piping in VoiceBase.h
633          (labelled "Disk stream not available in time")
634        - Update effects on sample rate & period size changes (to avoid
635          crashes and noise on such transitions).
636        - ignore missing LADSPA paths without ignoring valid LADSPA paths
637          (fixes #208)
638        - Fixed bug in LSCP grammar definition which caused a statement like
639          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
640          practically irrelevant, however it caused problems with the new LSCP
641          shell's auto completion feature).
642        - Fixed MIDI program change messages being ignored if quickly executed
643          after each other (fixes #231).
