2    
3    * packaging changes:    * packaging changes:
4        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
5          causing e.g. the libgig test to fail when
6          "./configure --disable-jack-driver" was used
7          (patch by Alexis Ballier)
8        - fixed compilation with gcc 4.3
9        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
10        - fixed configure so it detects x86_64 (#107)
11        - fixes for building with newer MinGW versions
12        - fix for building with bison 2.4 (#111)
13        - fixed building with libgig installed in a non-standard directory
14    
15      * general changes:
16        - bugfix: on some POSIX systems instrument editor plugins refused to
17          load as we used a non-portable Linux specific struct field
18          (fixes bug #70, patch by Ronald Baljeu)
19        - fixed endless loop which occured when loading an instrument editor
20          plugin DLL on Windows systems failed
21        - fixed memory leaks that occurred when liblinuxsampler was unloaded
22        - optimized the SynchronizedConfig class so it doesn't wait
23          unnecessarily long after an update
24        - added support for notifying instrument editors on note-on / note-off
25          events (e.g. to highlight the pressed keys on the virtual keyboard
26          of gigedit)
27        - added support for triggering notes by instrument editors (see above)
28        - be verbose on DLL load errors (on Linux)
29        - fixed di-harmonic triangle LFO implementation (this LFO implementation
30          is only used by very few systems, most pick the int math
31          implementation, which is usually faster)
32        - fixes for audio drivers with varying buffer sizes
33        - experimental support for running LinuxSampler as a DSSI, LV2 and
34          VST plugin
35        - notification events for stream/voice count statistics are now sent
36          only when there are actual changes
37        - added memory ordering constraints to improve stability on
38          multi-core and multi-cpu systems
39        - maximum voices and disk streams can now be altered at runtime
40        - fixed CPU feature detection on x86_64 (maybe fixes #108)
41        - automatic stacktrace mechanism is now turned off by default and can
42          be switched on by command line option "--stacktrace" (the automatic
43          stacktrace mechanism seems to be broken on most systems at the moment)
44    
45      * audio driver:
46        - removed the nonsense audio channel constraint (which was hard coded to
47          max. 100 audio channels) for most audio drivers
48        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
49          opposed to the LSCP specs
50        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
51          reflected the wrong value
52        - fixed a memory management bug in ASIO driver
53        - Makefile fix: JACK_CFLAGS wasn't used
54        - JACK: use jack_client_open instead of the deprecated
55          jack_client_new
56        - added (experimental) CoreAudio driver
57    
58      * MIDI driver:
59        - added JACK MIDI driver
60        - dispatch bank select as ordinary CC as well, the user might seriously
61          want to (mis)use it for some purpose ("fixed" in all current MIDI
62          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
63    
64      * instruments database:
65        - avoid time consuming samples scanning when adding instruments
66          to the instruments database
67        - added support for handling lost files in the instruments database
68        - Implemented option for adding instruments in separate directories
69          in the instruments database
70          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
71    
72      * Gigasampler format engine:
73        - fixed a memory leak that could happen when a channel was deleted
74          while notes were playing
75        - made it possible to load an instrument even if the audio thread
76          isn't running
77        - added partial support for the "Controller Triggered" MIDI rule,
78          enough for piano gigs with pedal noise samples
79        - minor fix: only mark FX sends as being modified if really the
80          respective FX send MIDI controller was used
81        - added support for GM global device volume SysEx message
82          (can be selected at compile time to either apply globally to the
83          whole sampler [default] or only to the sampler channels that are
84          connected to the respective MIDI input port the SysEx message arrived
85          on)
86        - bugfix: notes triggered at position 0 in the audio buffer were
87          sometimes wrongly killed in the same buffer, causing no sound to
88          be played
89        - added support for chromatic / drumkit mode Roland GS Sysex message
90          which is usally used to switch a part between chromatic sounds and
91          drumkit sounds (as opposed to their common default setting of MIDI
92          part 10 being a drumkit part and all other ones chromatic parts), in
93          LS however one can switch between the first 16 MIDI instrument maps
94          defined for the sampler
95        - made it possible to create multiple sample channels even if the
96          audio thread isn't running
97        - fixed crash when removing channel with active voices (#116)
98    
99      * LSCP server:
100        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
101          react on MIDI data arriving on certain sampler channels (so far only
102          Note-On and Note-Off events are sent via this LSCP event)
103        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
104          react on MIDI data arriving on certain MIDI input devices (so far only
105          Note-On and Note-Off events are sent via this LSCP event)
106        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
107          SET DB_INSTRUMENT FILE_PATH
108        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
109          frontends to send MIDI messages to specific sampler channel
110        - added two additional fields to GET FILE INSTRUMENT INFO command -
111          KEY_BINDINGS and KEYSWITCH_BINDINGS
112        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
113          was incorrect
114        - Optimized the retrieval of the MIDI instrument mappings
115        - added new LSCP command "SET VOICES" to globally alter the maximum
116          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
117          be triggered respectively
118        - added new LSCP command "SET STREAMS" to globally alter the maximum
119          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
120          which will be triggered respectively
121        - bugfix: retry if "select" returns EINTR (this fixes a crash when
122          a gigedit file dialog is opened)
123    
124      * Bug fixes:
125        - fixed a crash which occurs when removing a sampler channel waiting
126          to start instrument loading after another channel
127        - fixed a crash which occurs when removing a sampler channel with
128          instrument loading in progress (bug #113)
129        - fixed termination caused by uncaught exception when adding MIDI
130          instrument with PERSISTENT load mode
131        - fixed possible iterator invalidations when resetting the sampler
132        - fixed memory leaks when issuing the following LSCP commands:
133          GET AUDIO_OUTPUT_DRIVER INFO
134          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
135          GET MIDI_INPUT_DRIVER INFO
136          GET MIDI_INPUT_DRIVER_PARAMETER INFO
137        - fixed possible compilation error when sqlite is not present
138        - fixed orphaned pointers when setting maximum voices limit (bug #118)
139    
140    
141    Version 0.5.1 (6 December 2007)
142    
143      * packaging changes:
144        - added autoconf checks for pthread library
145        - added autoconf check for pthread bug found on certain NPTL-enabled
146          glibc versions (see Gentoo bug report #194076)
147        - added autoconf checks for MS Windows
148    
149      * general changes:
150        - bugfix: the thread used by an editor plugin didn't die when the
151          editor closed
152        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
153          out all the space. operator--() did not apply size_mask after
154          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
155          order to avoid problems with the _NonVolatileReader functions.
156        - bugfix: Stream.h: added a missing divide by BytesPerSample in
157          GetWriteSpace(). Since this function is currently only used in
158          the stream's qsort() compare function, it didn't trigger any
159          bugs.
160        - Resampler.h, Synthesizer.h: cubic interpolation now works in
161          24bit mode too. Faster method to read 24bit words on little
162          endian machines (x86): replaced 3 byte reads + shifts with a 1
163          unaligned 32bit read and shift
164        - experimental support for MS Windows (MIDI input via MME, AUDIO
165          output via ASIO)
166        - made handling of SIGINT signal (Ctrl-C) a bit more robust
167        - support for monitoring the total number of active disk streams
168          (new LSCP commands: GET TOTAL_STREAM_COUNT,
169          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
170    
171      * AUDIO driver:
172        - added Windows ASIO low latency audio driver
173    
174      * MIDI driver:
175        - added MME Windows MIDI driver
176    
177      * LSCP server:
178        - added support for Windows style path / filenames, however with
179          forward slash path separators instead of backslash
180          (i.e. "C:/foo/bar.gig")
181        - allow naughty liblscp to send non-string device parameters within
182          apostrophes as well
183        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
184          "LIST FILE INSTRUMENTS <file>" and
185          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
186          about an arbitrary instrument file on the system where the sampler is
187          running on
188    
189    Version 0.5.0 (15 October 2007)
190    
191      * packaging changes:
192        - config.h is not going to be installed along with liblinuxsampler's
193          API header files anymore
194        - only the API relevant header (and source) files will be exported to
195          the Doxygen API documentation (explicitly listed in Doxyfile.in)
196        - added completely new XCode project files for Mac OSX which is now
197          capable to execute our autoconf environment, thus no need anymore
198          to maintain the compile time configuration file (osx/version.h) for
199          OSX manually (patch by Toshi Nagata)
200        - fixed buggy boolean --enable-foo / --disable-foo configure script
201          parameters
202        - global.h now only covers global definitions that are needed for the
203          C++ API header files, all implementation internal global definitions
204          are now in global_private.h
205        - atomic.h is not exposed to the C++ API anymore
206        - no need to include config.h anymore for using LS's API header files
207        - fixed warnings in API doc generation
208    
209      * general changes:
210        - replaced the old, confusing MIDI program change mechanism by a
211          flexible MIDI instrument mapper which allows to map arbitrary
212          (MIDI bank, MIDI program) pairs with arbitrary
213          (engine type, instrument file, file index) triplets which will be
214          loaded on the respective channel when such MIDI program change
215          messages arrive, beside that, each entry allows to define a life-time
216          strategy for the instrument, so the user can define whether the
217          instrument should i.e. be permanently loaded (to be able to switch
218          quickly among sounds) or i.e. loaded just on demand when the
219          respective program change arrives (to safe RAM space), as well as a
220          global volume factor for each entry, so the user can adjust the volume
221          dynamic of his mapped instrument collection without having to modify
222          the instrument files, also one can manage arbitrary amount of such
223          MIDI instrument maps and assign each sampler channel individually
224          a certain map, so that i.e. separation of normal instruments and
225          drumkits is possible
226        - new notification events for tracking changes to audio/MIDI devices,
227          MIDI instrument maps, MIDI instruments, FX sends, global volume.
228        - sampler was limited to load max. 200 instruments in the background
229          due to a constant size RingBuffer FIFO which is now replaced by a
230          dynamic (unlimited) size std::list FIFO
231        - added FX sends, these allow to route audio signals to arbitrary audio
232          output channels for being processed by external effect processors
233          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
234          controllers
235        - global (sampler wide) volume can now be controlled at runtime
236        - Implemented new, improved notification system
237        - fixed compilation errors regarding OSX
238          (patch by Toshi Nagata)
239        - implemented instruments database
240        - added support for escape sequences to the instruments database
241        - added highly experimental support for on-the-fly instrument editing
242          within the sampler's process (by using instrument editor plugins),
243          you'll notice the new "Registered instrument editors:" message on
244          startup, added a new LSCP command:
245          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
246          to spawn a matching instrument editor for the instrument on the
247          given sampler channel, the plugin path can be overridden at compile
248          time with ./configure --enable-plugin-dir=/some/dir
249        - added experimental code for synchronizing instrument editors hosted
250          in the sampler's process to safely edit instruments while playing
251          without a crash (hopefully) by either suspending single regions
252          wherever possible or if unavoidable whole engine(s)
253        - fixed several issues in fundamental "Thread" class: set scheduling
254          policy and priority on thread level, set a minimum stack size for
255          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
256          threads simply inherited properties of starting thread instead of
257          setting their own policy and priority
258        - minor fix in our automatic stack trace mechanism on crashes, the
259          main process did not wait for the stack trace process to finish
260          its output
261        - fixed some minor memory leaks
262        - reenabled assembly features support, at the moment only for
263          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
264        - minor assembly fix in x86 features detection (don't use the PIC
265          register, to avoid relocations in the text segment at runtime)
266        - POSIX callback functions of Thread.h are hidden
267    
268      * MIDI driver:
269        - dispatch bank select (MSB and LSB) messages
270    
271      * audio driver:
272        - the ALSA audio output driver parameters now reflect the correct
273          parameter value ranges for the respective selected sound card
274          (patch by Till Wimmer, a bit fixed and extended)
275    
276      * Gigasampler format engine:
277        - if a filter is used and EG2 finishes before EG1, let the voice
278          die when EG2 has finished (this fixes a problem with clicks and
279          voice starvation for some gigs)
280        - playback is no longer disabled during instrument loading
281        - all notes playing on a channel that changes its instrument keep
282          playing with the old instrument until they get a note off
283          command
284        - EG fix: a release value of zero could cause noises or crash
285        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
286        - EG fine tuning: when attack is zero the EG starts at a level
287          above max sustain level, which means that there is a decay phase
288          even if sustain is 100%
289        - more EG fixes: the level could sometimes go below zero and cause
290          noises or crashes
291        - minor fix of EGDecay (patch by Toshi Nagata)
292        - fixed compiler error when --enable-override-filter-type was
293          supplied to the configure script (fixes #46)
294        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
295          instead of a fix value
296        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
297          127 (solo mode) only kill voices if the respective mode really
298          changed
299    
300      * LSCP server:
301        - fixed compile time error for old Bison versions
302          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
303        - parser now supports extended ASCII character set
304          (up to ASCII code 255, i.e. includes now umlauts and accents)
305        - filename arguments in LSCP commands now allow to use escape
306          sequences, that is directly literal as one of: \', \", \\, \n, \r,
307          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
308          code value like \xf2) (fixes bug #24)
309        - the following LSCP commands now also support escape sequences for at
310          least one of their text-based parameters (i.e. name, description):
311          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
312          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
313          "SET DB_INSTRUMENT_DIRECTORY NAME",
314          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
315          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
316          "FIND DB_INSTRUMENT_DIRECTORIES"
317        - returns verbose syntax errors (line and column where syntax error
318          occured, the unexpected character and the actually expected, possible
319          character(s), the latter only if less than 5 possibilities)
320        - made sure that LSCP syntax is not affected by gigedit locale
321          settings
322        - bugfix regarding strings parameter lists: all comma separated lists
323          of strings were treated as being one string containing commas
324          (fixes #57)
325    
326      * Bug fixes:
327        - fixed crash occurring on certain LSCP scripts (Bug 39)
328        - another thread safety fix for lscp "load engine" and "set
329          channel audio output device"
330        - fixed a crash which occurs when reassigning the same engine
331          on a sampler channel with connected MIDI device
332        - fixed a crash which occurs when changing the number of ports of a MIDI
333          device connected to a sampler channel to number less then or equal
334          to the index of the port to which the sampler channel is connected.
335        - The previous bindings were not been disconnected when altering
336          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
337          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
338        - The active stream/voice count statistic was incorrect.
339        - notification events were not been sent for some sampler
340          channel changes
341        - added default min and max values to restrict the number of allowed
342          audio output channels and MIDI input ports
343        - the connection to the PCM interface is now closed when destroying
344          an audio output device
345        - files with slash in their path or filename could not be loaded
346    
347      * test cases:
348        - updated and fixed (haven't been touched in a while)
349    
350    Version 0.4.0 (24 November 2006)
351    
352      * packaging changes:
353        - changed deprecated copyright attribute to license; added ldconfig
354          to post-(un)install steps; added devel package for liblinuxsampler;
355          to linuxsampler.spec (RPM)
356      - install necessary development header files for allowing 3rd party      - install necessary development header files for allowing 3rd party

387        cutoff frequency, not just resonance.        cutoff frequency instead of resonance.
388        - added support for gig parameter Resonance.
389      - fixed bug in sysex handling (patch by Juan Linietsky)      - fixed bug in sysex handling (patch by Juan Linietsky)
390        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
391          which can be overridden with --enable-global-attenuation
392        - EG fixes: made the length of "attack hold" stage more
393          accurate. Release stage can now start before attack stage
394          ends. Cancel release didn't work when sustain was zero. Attack
395          time now has a minimal value to prevent clicks.
396        - fixed pitch changes larger than one octave
397        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
398        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
399          all modes can be altered via standard GM messages, that is CC5 for
400          altering portamento time, CC65 for enabling / disabling portamento
401          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
402        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
403          parameter) and crossfade
404        - added support for the "attenuation controller threshold" gig
405          parameter
406        - added smoothing of volume changes caused by control change
407          messages
408        - sample loop parameters are now taken from the DimensionRegion
409          instead of the wave chunk
410        - fixed keyswitching for v3 gigs with a number of keyswitch splits
411          not equal to a power of two
412        - reimplementation of the filter algorithm. The new filter is more
413          accurate and supports all gig filter types, including bandreject
414          and lowpass turbo.
415        - real support for 24 bit samples - samples are not truncated to
416          16 bits anymore
417        - support for aftertouch (channel pressure, not polyphonic
418          aftertouch)
419        - LFO1 behaviour fixed (dampening from max volume instead of
420          amplifying from 0)
421    
422    * LSCP server:    * LSCP server:
423      - fixed application exit on broken pipe error (fixes bug #20)      - fixed application exit on broken pipe error (fixes bug #20)
424        - fixed the notification messages delay due to lack of
425          network activity (fixes bug #26)
426        - fixed parser bug which occured on space(s) within device parameters
427          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
428    
429      * audio driver:
430        - added aRts audio output driver (by no means RT safe)
431    
432    * MIDI driver:    * MIDI driver:
433      - fixed legacy sysex code which caused dispatching of MIDI SysEx      - fixed legacy sysex code which caused dispatching of MIDI SysEx
434        messages several times instead of once        messages several times instead of once
435        - API extension for MIDI drivers which already supply exact time stamps
436          for events (i.e. for offline rendering based MIDI drivers)
437        - added checks for bad MIDI data
438    
439      * linuxsampler application:
440        - show available sampler engine types on startup
441

450        - support for sostenuto pedal
451        - support for monitoring the total number of active voices
452          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
453          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
454        - fixed some memory management errors
455        - fixed some concurrency problems that could lead to crashes when
456          LSCP commands were executed
457        - fixed crash when instrument loading failed previously on the same
458          sampler channel (fixes bug #36)
