Sticky Revision: |
* introduced 'synthesis mode' to reduce the amount of code and conditionals for the current synthesis case in the main synthesis loop * support for MMX and SSE(1) in the core synthesis algorithms (CPU feature detection at runtime, only x86 so far)
* fixed segfault which occured whenever a voice stole a voice and was in turn killed in the same audio fragment, to fix that the MIDI key informations are now updated only after all voices were processed
* bunch of bugfixes (e.g. segfault on voice stealing)
* libgig: fixed panorama value in DimensionRegion (invalid conversion from signed 7 bit to signed 8 bit) * src/linuxsampler.cpp: stacktrace is now automatically shown on fatal errors (that is segmentation faults, etc.), gdb should be installed for this to work * gig::Voice: tiny accuracy fix of pan calculation * replaced old pool classes by completely new ones which now offer Iterator abstraction
* gcc-c++ 3.4.1 compability fixes.
* added first two experimental voice stealing algorithms ('oldestkey' - which just steals the oldest voice on the oldest key and 'keymask' - which tries to pick the oldest voice on the same key where the new voice should be spawned, if it fails it behaves like 'oldestkey'), the desired algorithm can be selected at compile time (see Engine.h) will be configurable via LSCP soon though
* added support for scale tuning via MIDI GS system exclusive message
* added support for release trigger dimension (that is voices which are spawned when a key was released) * libgig: bugfix in dimension region switching
* implemented key groups (a.k.a exclusive groups) which is important for drum patches and monphonic instruments * src/engines/gig/Engine.cpp: bugfix in ProcessNoteOn() - did not always stick the note on event to the respective key's own event list although e.g. the EGADRS expects it to find there
* added support for layers * fixed initial pitch calculation which did not honor the sample's own sample rate
* set default volume to 1.0 in Gigasampler engine (was 0.0) * implemented "SET CHANNEL AUDIO_OUTPUT_CHANNEL" LSCP command * fixed "GET ENGINE INFO" LSCP command * fixed "GET CHANNEL INFO" LSCP command * src/network/lscp.y: fixed 'stringval' rule (returned string with formal apostrophes), fixed 'dotnum' rule (ignored position after decimal point)
* Load Instrument patch applied; this patch makes the LOAD INSTRUMENT command to return immediately, almost/always with an OK response, while spawning the proper instrument file loading in the background. * New INSTRUMENT_STATUS field on GET CHANNEL INFO result set; the instrument status value holds the load progress percentage if positive, otherwise a negative value is evidence of a load exception error. * VERSION is now set to 0.2.
* Added methods for CHANNEL_INFO command
* biquad filter parameters are now calculated outside the interpolate loop for better performance * couple of loop unroll optimizations * filter is now enabled by default * cubic interpolation is now enabled by default * reduced debug level to 1 to lower verbosity * raised default limit for voices to 128 * raised default limit for streams to 150 * added some compiler optimization flags (-ffast-math -march -mcpu)
updated copyright header for 2004
* completely restructured source tree * implemented multi channel support * implemented instrument manager, which controls sharing of instruments between multiple sampler engines / sampler channels * created abstract classes 'AudioOutputDevice' and 'MidiInputDevice' for convenient implementation of further audio output driver and MIDI input driver for LinuxSampler * implemented following LSCP commands: 'SET CHANNEL MIDI INPUT TYPE', 'LOAD ENGINE', 'GET CHANNELS', 'ADD CHANNEL', 'REMOVE CHANNEL', 'SET CHANNEL AUDIO OUTPUT TYPE' * temporarily removed all command line options * LSCP server is now launched by default
