DEFAULT_WRAP_ELEMENTS set to 0 in + order to avoid problems with the _NonVolatileReader functions. + - bugfix: Stream.h: added a missing divide by BytesPerSample in + GetWriteSpace(). Since this function is currently only used in + the stream's qsort() compare function, it didn't trigger any + bugs. + - Resampler.h, Synthesizer.h: cubic interpolation now works in + 24bit mode too. Faster method to read 24bit words on little + endian machines (x86): replaced 3 byte reads + shifts with a 1 + unaligned 32bit read and shift + - experimental support for MS Windows (MIDI input via MME, AUDIO + output via ASIO) + - made handling of SIGINT signal (Ctrl-C) a bit more robust + - support for monitoring the total number of active disk streams + (new LSCP commands: GET TOTAL_STREAM_COUNT, + SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT) + + * AUDIO driver: + - added Windows ASIO low latency audio driver + + * MIDI driver: + - added MME Windows MIDI driver + + * LSCP server: + - added support for Windows style path / filenames, however with + forward slash path separators instead of backslash + (i.e. "C:/foo/bar.gig") + - allow naughty liblscp to send non-string device parameters within + apostrophes as well + - added new LSCP commands: "GET FILE INSTRUMENTS ", + "LIST FILE INSTRUMENTS " and + "GET FILE INSTRUMENT INFO " for retrieving informations + about an arbitrary instrument file on the system where the sampler is + running on + +Version 0.5.0 (15 October 2007) + + * packaging changes: + - config.h is not going to be installed along with liblinuxsampler's + API header files anymore + - only the API relevant header (and source) files will be exported to + the Doxygen API documentation (explicitly listed in Doxyfile.in) + - added completely new XCode project files for Mac OSX which is now + capable to execute our autoconf environment, thus no need anymore + to maintain the compile time configuration file (osx/version.h) for + OSX manually (patch by Toshi Nagata) + - fixed buggy boolean --enable-foo / --disable-foo configure script + parameters + - global.h now only covers global definitions that are needed for the + C++ API header files, all implementation internal global definitions + are now in global_private.h + - atomic.h is not exposed to the C++ API anymore + - no need to include config.h anymore for using LS's API header files + - fixed warnings in API doc generation + + * general changes: - replaced the old, confusing MIDI program change mechanism by a flexible MIDI instrument mapper which allows to map arbitrary - (MIDI bank MSB, MIDI bank LSB, MIDI program) triplets with arbitrary + (MIDI bank, MIDI program) pairs with arbitrary (engine type, instrument file, file index) triplets which will be loaded on the respective channel when such MIDI program change messages arrive, beside that, each entry allows to define a life-time @@ -13,15 +92,133 @@ respective program change arrives (to safe RAM space), as well as a global volume factor for each entry, so the user can adjust the volume dynamic of his mapped instrument collection without having to modify - the instrument files + the instrument files, also one can manage arbitrary amount of such + MIDI instrument maps and assign each sampler channel individually + a certain map, so that i.e. separation of normal instruments and + drumkits is possible + - new notification events for tracking changes to audio/MIDI devices, + MIDI instrument maps, MIDI instruments, FX sends, global volume. + - sampler was limited to load max. 200 instruments in the background + due to a constant size RingBuffer FIFO which is now replaced by a + dynamic (unlimited) size std::list FIFO + - added FX sends, these allow to route audio signals to arbitrary audio + output channels for being processed by external effect processors + (i.e. jack-rack), the send levels are controllable via arbitrary MIDI + controllers + - global (sampler wide) volume can now be controlled at runtime + - Implemented new, improved notification system + - fixed compilation errors regarding OSX + (patch by Toshi Nagata) + - implemented instruments database + - added support for escape sequences to the instruments database + - added highly experimental support for on-the-fly instrument editing + within the sampler's process (by using instrument editor plugins), + you'll notice the new "Registered instrument editors:" message on + startup, added a new LSCP command: + "EDIT CHANNEL INSTRUMENT " + to spawn a matching instrument editor for the instrument on the + given sampler channel, the plugin path can be overridden at compile + time with ./configure --enable-plugin-dir=/some/dir + - added experimental code for synchronizing instrument editors hosted + in the sampler's process to safely edit instruments while playing + without a crash (hopefully) by either suspending single regions + wherever possible or if unavoidable whole engine(s) + - fixed several issues in fundamental "Thread" class: set scheduling + policy and priority on thread level, set a minimum stack size for + thread (TODO: a reasonable value yet to be tested), bugfix: non-RT + threads simply inherited properties of starting thread instead of + setting their own policy and priority + - minor fix in our automatic stack trace mechanism on crashes, the + main process did not wait for the stack trace process to finish + its output + - fixed some minor memory leaks + - reenabled assembly features support, at the moment only for + enabling a fast denormal FPU mode (x86 platforms supporting SSE2) + - minor assembly fix in x86 features detection (don't use the PIC + register, to avoid relocations in the text segment at runtime) + - POSIX callback functions of Thread.h are hidden * MIDI driver: - dispatch bank select (MSB and LSB) messages + * audio driver: + - the ALSA audio output driver parameters now reflect the correct + parameter value ranges for the respective selected sound card + (patch by Till Wimmer, a bit fixed and extended) + * Gigasampler format engine: - if a filter is used and EG2 finishes before EG1, let the voice die when EG2 has finished (this fixes a problem with clicks and voice starvation for some gigs) + - playback is no longer disabled during instrument loading + - all notes playing on a channel that changes its instrument keep + playing with the old instrument until they get a note off + command + - EG fix: a release value of zero could cause noises or crash + - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB) + - EG fine tuning: when attack is zero the EG starts at a level + above max sustain level, which means that there is a decay phase + even if sustain is 100% + - more EG fixes: the level could sometimes go below zero and cause + noises or crashes + - minor fix of EGDecay (patch by Toshi Nagata) + - fixed compiler error when --enable-override-filter-type was + supplied to the configure script (fixes #46) + - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS + instead of a fix value + - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode), + 127 (solo mode) only kill voices if the respective mode really + changed + + * LSCP server: + - fixed compile time error for old Bison versions + (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata) + - parser now supports extended ASCII character set + (up to ASCII code 255, i.e. includes now umlauts and accents) + - filename arguments in LSCP commands now allow to use escape + sequences, that is directly literal as one of: \', \", \\, \n, \r, + \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII + code value like \xf2) (fixes bug #24) + - the following LSCP commands now also support escape sequences for at + least one of their text-based parameters (i.e. name, description): + "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT", + "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND", + "SET DB_INSTRUMENT_DIRECTORY NAME", + "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME", + "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS", + "FIND DB_INSTRUMENT_DIRECTORIES" + - returns verbose syntax errors (line and column where syntax error + occured, the unexpected character and the actually expected, possible + character(s), the latter only if less than 5 possibilities) + - made sure that LSCP syntax is not affected by gigedit locale + settings + - bugfix regarding strings parameter lists: all comma separated lists + of strings were treated as being one string containing commas + (fixes #57) + + * Bug fixes: + - fixed crash occurring on certain LSCP scripts (Bug 39) + - another thread safety fix for lscp "load engine" and "set + channel audio output device" + - fixed a crash which occurs when reassigning the same engine + on a sampler channel with connected MIDI device + - fixed a crash which occurs when changing the number of ports of a MIDI + device connected to a sampler channel to number less then or equal + to the index of the port to which the sampler channel is connected. + - The previous bindings were not been disconnected when altering + the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for + unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE). + - The active stream/voice count statistic was incorrect. + - notification events were not been sent for some sampler + channel changes + - added default min and max values to restrict the number of allowed + audio output channels and MIDI input ports + - the connection to the PCM interface is now closed when destroying + an audio output device + - files with slash in their path or filename could not be loaded + + * test cases: + - updated and fixed (haven't been touched in a while) Version 0.4.0 (24 November 2006)
