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, 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 + strategy for the instrument, so the user can define whether the + instrument should i.e. be permanently loaded (to be able to switch + quickly among sounds) or i.e. loaded just on demand when the + 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, 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 + -
