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    
14      * general changes:
15        - bugfix: on some POSIX systems instrument editor plugins refused to
16          load as we used a non-portable Linux specific struct field
17          (fixes bug #70, patch by Ronald Baljeu)
18        - fixed endless loop which occured when loading an instrument editor
19          plugin DLL on Windows systems failed
20        - fixed memory leaks that occurred when liblinuxsampler was unloaded
21        - optimized the SynchronizedConfig class so it doesn't wait
22          unnecessarily long after an update
23        - added support for notifying instrument editors on note-on / note-off
24          events (e.g. to highlight the pressed keys on the virtual keyboard
25          of gigedit)
26        - added support for triggering notes by instrument editors (see above)
27        - be verbose on DLL load errors (on Linux)
28        - fixed di-harmonic triangle LFO implementation (this LFO implementation
29          is only used by very few systems, most pick the int math
30          implementation, which is usually faster)
31        - fixes for audio drivers with varying buffer sizes
32        - experimental support for running LinuxSampler as a DSSI, LV2 and
33          VST plugin
34        - notification events for stream/voice count statistics are now sent
35          only when there are actual changes
36        - added memory ordering constraints to improve stability on
37          multi-core and multi-cpu systems
38        - maximum voices and disk streams can now be altered at runtime
39    
40      * audio driver:
41        - removed the nonsense audio channel constraint (which was hard coded to
42          max. 100 audio channels) for most audio drivers
43        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
44          opposed to the LSCP specs
45        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
46          reflected the wrong value
47        - fixed a memory management bug in ASIO driver
48        - Makefile fix: JACK_CFLAGS wasn't used
49        - JACK: use jack_client_open instead of the deprecated
50          jack_client_new
51    
52      * MIDI driver:
53        - added JACK MIDI driver
54        - dispatch bank select as ordinary CC as well, the user might seriously
55          want to (mis)use it for some purpose ("fixed" in all current MIDI
56          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
57    
58      * instruments database:
59        - avoid time consuming samples scanning when adding instruments
60          to the instruments database
61        - added support for handling lost files in the instruments database
62        - Implemented option for adding instruments in separate directories
63          in the instruments database
64          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
65    
66      * Gigasampler format engine:
67        - fixed a memory leak that could happen when a channel was deleted
68          while notes were playing
69        - made it possible to load an instrument even if the audio thread
70          isn't running
71        - added partial support for the "Controller Triggered" MIDI rule,
72          enough for piano gigs with pedal noise samples
73        - minor fix: only mark FX sends as being modified if really the
74          respective FX send MIDI controller was used
75        - added support for GM global device volume SysEx message
76          (can be selected at compile time to either apply globally to the
77          whole sampler [default] or only to the sampler channels that are
78          connected to the respective MIDI input port the SysEx message arrived
79          on)
80        - bugfix: notes triggered at position 0 in the audio buffer were
81          sometimes wrongly killed in the same buffer, causing no sound to
82          be played
83        - added support for chromatic / drumkit mode Roland GS Sysex message
84          which is usally used to switch a part between chromatic sounds and
85          drumkit sounds (as opposed to their common default setting of MIDI
86          part 10 being a drumkit part and all other ones chromatic parts), in
87          LS however one can switch between the first 16 MIDI instrument maps
88          defined for the sampler
89        - made it possible to create multiple sample channels even if the
90          audio thread isn't running
91    
92      * LSCP server:
93        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
94          react on MIDI data arriving on certain sampler channels (so far only
95          Note-On and Note-Off events are sent via this LSCP event)
96        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
97          react on MIDI data arriving on certain MIDI input devices (so far only
98          Note-On and Note-Off events are sent via this LSCP event)
99        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
100          SET DB_INSTRUMENT FILE_PATH
101        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
102          frontends to send MIDI messages to specific sampler channel
103        - added two additional fields to GET FILE INSTRUMENT INFO command -
104          KEY_BINDINGS and KEYSWITCH_BINDINGS
105        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
106          was incorrect
107        - Optimized the retrieval of the MIDI instrument mappings
108        - added new LSCP command "SET VOICES" to globally alter the maximum
109          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
110          be triggered respectively
111        - added new LSCP command "SET STREAMS" to globally alter the maximum
112          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
113          which will be triggered respectively
114        - bugfix: retry if "select" returns EINTR (this fixes a crash when
115          a gigedit file dialog is opened)
116    
117      * Bug fixes:
118        - fixed a crash which occurs when removing a sampler channel waiting
119          to start instrument loading after another channel
120    
121    
122    Version 0.5.1 (6 December 2007)
123    
124      * packaging changes:
125        - added autoconf checks for pthread library
126        - added autoconf check for pthread bug found on certain NPTL-enabled
127          glibc versions (see Gentoo bug report #194076)
128        - added autoconf checks for MS Windows
129    
130      * general changes:
131        - bugfix: the thread used by an editor plugin didn't die when the
132          editor closed
133        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
134          out all the space. operator--() did not apply size_mask after
135          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
136          order to avoid problems with the _NonVolatileReader functions.
137        - bugfix: Stream.h: added a missing divide by BytesPerSample in
138          GetWriteSpace(). Since this function is currently only used in
139          the stream's qsort() compare function, it didn't trigger any
140          bugs.
141        - Resampler.h, Synthesizer.h: cubic interpolation now works in
142          24bit mode too. Faster method to read 24bit words on little
143          endian machines (x86): replaced 3 byte reads + shifts with a 1
144          unaligned 32bit read and shift
145        - experimental support for MS Windows (MIDI input via MME, AUDIO
146          output via ASIO)
147        - made handling of SIGINT signal (Ctrl-C) a bit more robust
148        - support for monitoring the total number of active disk streams
149          (new LSCP commands: GET TOTAL_STREAM_COUNT,
150          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
151    
152      * AUDIO driver:
153        - added Windows ASIO low latency audio driver
154    
155      * MIDI driver:
156        - added MME Windows MIDI driver
157    
158      * LSCP server:
159        - added support for Windows style path / filenames, however with
160          forward slash path separators instead of backslash
161          (i.e. "C:/foo/bar.gig")
162        - allow naughty liblscp to send non-string device parameters within
163          apostrophes as well
164        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
165          "LIST FILE INSTRUMENTS <file>" and
166          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
167          about an arbitrary instrument file on the system where the sampler is
168          running on
169    
170    Version 0.5.0 (15 October 2007)
171    
172      * packaging changes:
173        - config.h is not going to be installed along with liblinuxsampler's
174          API header files anymore
175        - only the API relevant header (and source) files will be exported to
176          the Doxygen API documentation (explicitly listed in Doxyfile.in)
177        - added completely new XCode project files for Mac OSX which is now
178          capable to execute our autoconf environment, thus no need anymore
179          to maintain the compile time configuration file (osx/version.h) for
180          OSX manually (patch by Toshi Nagata)
181        - fixed buggy boolean --enable-foo / --disable-foo configure script
182          parameters
183        - global.h now only covers global definitions that are needed for the
184          C++ API header files, all implementation internal global definitions
185          are now in global_private.h
186        - atomic.h is not exposed to the C++ API anymore
187        - no need to include config.h anymore for using LS's API header files
188        - fixed warnings in API doc generation
189    
190      * general changes:
191        - replaced the old, confusing MIDI program change mechanism by a
192          flexible MIDI instrument mapper which allows to map arbitrary
193          (MIDI bank, MIDI program) pairs with arbitrary
194          (engine type, instrument file, file index) triplets which will be
195          loaded on the respective channel when such MIDI program change
196          messages arrive, beside that, each entry allows to define a life-time
197          strategy for the instrument, so the user can define whether the
198          instrument should i.e. be permanently loaded (to be able to switch
199          quickly among sounds) or i.e. loaded just on demand when the
200          respective program change arrives (to safe RAM space), as well as a
201          global volume factor for each entry, so the user can adjust the volume
202          dynamic of his mapped instrument collection without having to modify
203          the instrument files, also one can manage arbitrary amount of such
204          MIDI instrument maps and assign each sampler channel individually
205          a certain map, so that i.e. separation of normal instruments and
206          drumkits is possible
207        - new notification events for tracking changes to audio/MIDI devices,
208          MIDI instrument maps, MIDI instruments, FX sends, global volume.
209        - sampler was limited to load max. 200 instruments in the background
210          due to a constant size RingBuffer FIFO which is now replaced by a
211          dynamic (unlimited) size std::list FIFO
212        - added FX sends, these allow to route audio signals to arbitrary audio
213          output channels for being processed by external effect processors
214          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
215          controllers
216        - global (sampler wide) volume can now be controlled at runtime
217        - Implemented new, improved notification system
218        - fixed compilation errors regarding OSX
219          (patch by Toshi Nagata)
220        - implemented instruments database
221        - added support for escape sequences to the instruments database
222        - added highly experimental support for on-the-fly instrument editing
223          within the sampler's process (by using instrument editor plugins),
224          you'll notice the new "Registered instrument editors:" message on
225          startup, added a new LSCP command:
226          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
227          to spawn a matching instrument editor for the instrument on the
228          given sampler channel, the plugin path can be overridden at compile
229          time with ./configure --enable-plugin-dir=/some/dir
230        - added experimental code for synchronizing instrument editors hosted
231          in the sampler's process to safely edit instruments while playing
232          without a crash (hopefully) by either suspending single regions
233          wherever possible or if unavoidable whole engine(s)
234        - fixed several issues in fundamental "Thread" class: set scheduling
235          policy and priority on thread level, set a minimum stack size for
236          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
237          threads simply inherited properties of starting thread instead of
238          setting their own policy and priority
239        - minor fix in our automatic stack trace mechanism on crashes, the
240          main process did not wait for the stack trace process to finish
241          its output
242        - fixed some minor memory leaks
243        - reenabled assembly features support, at the moment only for
244          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
245        - minor assembly fix in x86 features detection (don't use the PIC
246          register, to avoid relocations in the text segment at runtime)
247        - POSIX callback functions of Thread.h are hidden
248    
249      * MIDI driver:
250        - dispatch bank select (MSB and LSB) messages
251    
252      * audio driver:
253        - the ALSA audio output driver parameters now reflect the correct
254          parameter value ranges for the respective selected sound card
255          (patch by Till Wimmer, a bit fixed and extended)
256    
257      * Gigasampler format engine:
258        - if a filter is used and EG2 finishes before EG1, let the voice
259          die when EG2 has finished (this fixes a problem with clicks and
260          voice starvation for some gigs)
261        - playback is no longer disabled during instrument loading
262        - all notes playing on a channel that changes its instrument keep
263          playing with the old instrument until they get a note off
264          command
265        - EG fix: a release value of zero could cause noises or crash
266        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
267        - EG fine tuning: when attack is zero the EG starts at a level
268          above max sustain level, which means that there is a decay phase
269          even if sustain is 100%
270        - more EG fixes: the level could sometimes go below zero and cause
271          noises or crashes
272        - minor fix of EGDecay (patch by Toshi Nagata)
273        - fixed compiler error when --enable-override-filter-type was
274          supplied to the configure script (fixes #46)
275        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
276          instead of a fix value
277        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
278          127 (solo mode) only kill voices if the respective mode really
279          changed
280    
281      * LSCP server:
282        - fixed compile time error for old Bison versions
283          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
284        - parser now supports extended ASCII character set
285          (up to ASCII code 255, i.e. includes now umlauts and accents)
286        - filename arguments in LSCP commands now allow to use escape
287          sequences, that is directly literal as one of: \', \", \\, \n, \r,
288          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
289          code value like \xf2) (fixes bug #24)
290        - the following LSCP commands now also support escape sequences for at
291          least one of their text-based parameters (i.e. name, description):
292          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
293          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
294          "SET DB_INSTRUMENT_DIRECTORY NAME",
295          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
296          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
297          "FIND DB_INSTRUMENT_DIRECTORIES"
298        - returns verbose syntax errors (line and column where syntax error
299          occured, the unexpected character and the actually expected, possible
300          character(s), the latter only if less than 5 possibilities)
301        - made sure that LSCP syntax is not affected by gigedit locale
302          settings
303        - bugfix regarding strings parameter lists: all comma separated lists
304          of strings were treated as being one string containing commas
305          (fixes #57)
306    
307      * Bug fixes:
308        - fixed crash occurring on certain LSCP scripts (Bug 39)
309        - another thread safety fix for lscp "load engine" and "set
310          channel audio output device"
311        - fixed a crash which occurs when reassigning the same engine
312          on a sampler channel with connected MIDI device
313        - fixed a crash which occurs when changing the number of ports of a MIDI
314          device connected to a sampler channel to number less then or equal
315          to the index of the port to which the sampler channel is connected.
316        - The previous bindings were not been disconnected when altering
317          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
318          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
319        - The active stream/voice count statistic was incorrect.
320        - notification events were not been sent for some sampler
321          channel changes
322        - added default min and max values to restrict the number of allowed
323          audio output channels and MIDI input ports
324        - the connection to the PCM interface is now closed when destroying
325          an audio output device
326        - files with slash in their path or filename could not be loaded
327    
328      * test cases:
329        - updated and fixed (haven't been touched in a while)
330    
331    Version 0.4.0 (24 November 2006)
332    
333      * packaging changes:
334        - changed deprecated copyright attribute to license; added ldconfig
335          to post-(un)install steps; added devel package for liblinuxsampler;
336          to linuxsampler.spec (RPM)
337        - install necessary development header files for allowing 3rd party
338          applications to link against liblinuxsampler
339        - liblinuxsampler's API documentation can be generated with 'make docs'
340          (Doxygen required)
341        - added benchmark to automatically detect the best triangle LFO
342          implementation (currently either an integer math solution or a
343          di-harmonic approximation), automatic detection can be overriden
344          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
345          configure script argument though (mandatory for cross-compilation)
346        - do not automatically pick optimized gcc flags if the user already
347          provided some on his own (as CXXFLAGS)
348        - added compile time option to disable processing of All-Notes-Off MIDI
349          messages
350        - added compile time options to allow disabling the various audio and
351          MIDI drivers
352        - fixed automatic GCC CPU switch detection on PPC
353          (patch by Ebrahim Mayat)
354    
355      * Gigasampler format engine:
356        - extensive synthesis optimization
357          (reimplementation of EGs and LFO(s), removed synthesis parameter
358          prerendering and the synthesis parameter matrix in general, splitting
359          each audio fragment into subfragments now where each subfragment uses
360          constant pitch and filter coefficients. The volume coefficient is
361          linearly interpolated inside a subfragment, unless
362          --disable-interpolate-volume is set.)
363        - fine tuning of the EG modulation parameters
364        - improved filter cutoff calculation by adding support for the
365          following gig parameters: Cutoff freq (used when no cutoff
366          controller is defined), Control invert, Minimum cutoff, Velocity
367          curve and Velocity range. The keyboard tracking now scales
368          cutoff frequency instead of resonance.
369        - added support for gig parameter Resonance.
370        - fixed bug in sysex handling (patch by Juan Linietsky)
371        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
372          which can be overridden with --enable-global-attenuation
373        - EG fixes: made the length of "attack hold" stage more
374          accurate. Release stage can now start before attack stage
375          ends. Cancel release didn't work when sustain was zero. Attack
376          time now has a minimal value to prevent clicks.
377        - fixed pitch changes larger than one octave
378        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
379        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
380          all modes can be altered via standard GM messages, that is CC5 for
381          altering portamento time, CC65 for enabling / disabling portamento
382          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
383        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
384          parameter) and crossfade
385        - added support for the "attenuation controller threshold" gig
386          parameter
387        - added smoothing of volume changes caused by control change
388          messages
389        - sample loop parameters are now taken from the DimensionRegion
390          instead of the wave chunk
391        - fixed keyswitching for v3 gigs with a number of keyswitch splits
392          not equal to a power of two
393        - reimplementation of the filter algorithm. The new filter is more
394          accurate and supports all gig filter types, including bandreject
395          and lowpass turbo.
396        - real support for 24 bit samples - samples are not truncated to
397          16 bits anymore
398        - support for aftertouch (channel pressure, not polyphonic
399          aftertouch)
400        - LFO1 behaviour fixed (dampening from max volume instead of
401          amplifying from 0)
402    
403      * LSCP server:
404        - fixed application exit on broken pipe error (fixes bug #20)
405        - fixed the notification messages delay due to lack of
406          network activity (fixes bug #26)
407        - fixed parser bug which occured on space(s) within device parameters
408          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
409    
410      * audio driver:
411        - added aRts audio output driver (by no means RT safe)
412    
413      * MIDI driver:
414        - fixed legacy sysex code which caused dispatching of MIDI SysEx
415          messages several times instead of once
416        - API extension for MIDI drivers which already supply exact time stamps
417          for events (i.e. for offline rendering based MIDI drivers)
418        - added checks for bad MIDI data
419    
420      * linuxsampler application:
421        - show available sampler engine types on startup
422    
423      * general changes:
424        - support for muting sampler channels and solo mode of the same, two new
425          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
426          fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
427          introduced for this, the behavior is the same like on a mixer console
428          (patch by Grigor Iliev, a bit adjusted). Also added configure option
429          --enable-process-muted-channels which can be used to enable the
430          processing of muted channels.
431        - support for sostenuto pedal
432        - support for monitoring the total number of active voices
433          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
434          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
435        - fixed some memory management errors
436        - fixed some concurrency problems that could lead to crashes when
437          LSCP commands were executed
438        - fixed crash when instrument loading failed previously on the same
439          sampler channel (fixes bug #36)
440    
441    Version 0.3.3 (15 July 2005)
442    
443      * packaging changes:
444        - fixed compilation with gcc 4.0
445    
446      * Gigasampler format engine:
447        - LFO preprocessing was performed even though the respective LFO was
448          disabled by the instrument patch (minor efficiency fix)
449        - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
450          for volume ramp downs in the same fragment (needed for current voice
451          stealing implementation) then simply inform the user with a warning
452          about possible click sounds and reduce the volume ramp down
453          appropriately instead of cancelling the audio device connection
454    
455    Version 0.3.2 (24 June 2005)
456    
457      * packaging changes:
458      - updated autotools build files to compile on OS X      - updated autotools build files to compile on OS X
459        (conditional compilation of CoreMIDI and MidiShare drivers)        (conditional compilation of CoreMIDI and MidiShare drivers)
460    * support for the gig parameters for "release velocity response"      - hand-crafted assembly optimization code can be disabled with
461      curves        './configure --disable-asm' (definitely not recommended)
462    * fine tuning of the EGADSR envelope      - fixed 'make dist' rule to include all necessary files
463        - require automake (>= 1.5) for 'make -f Makefile.cvs'
464          (due to 'dist-bzip2' automake option)
465    
466      * Gigasampler format engine:
467        - support for the gig parameters for "release velocity response" curves
468        - fine tuning of the EGADSR envelope
469        - volume of release triggered samples now depends on note-on velocity,
470          note length and gig parameter "release trigger decay" instead of
471          note-off velocity.
472        - revised voice stealing
473          (fixes crash and endless loop caused by voice stealing)
474        - don't reset scale tuning on instrument or audio output device change
475        - handle key group conflicts right at the beginning of each fragment
476          instead of when the respective voice is actually launched
477          (fixes undefined behavior if stolen voices belonged to a key group -
478          this case was followed by a "killed voice survived" error message)
479        - fixed minor issue with null/silence samples
480          (those stole voices even though they don't need a voice at all which
481          resulted in "voice stealing didn't work out" messages)
482        - don't reset volume, pan, pitch and MIDI controller values on
483          instrument or audio output device change
484    
485      * LSCP server:
486        - fixed some crashes (patch by Grigor Iliev, fixes #19)
487        - fixed LSCP event "CHANNEL_INFO" notification
488          (e.g. did not notify on volume changes or MIDI program change events)
489    
490      * linuxsampler application:
491        - added command line parameters --lscp-addr and --lscp-port to override
492          default IP address and port of LSCP server
493    
494  Version 0.3.1 (24 May 2005)  Version 0.3.1 (24 May 2005)
