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