| Sticky Revision: |
* fine tuning of the EG modulation parameters
* minor efficiency fix (LFO preprocessing was performed even though the respective LFO was disabled by the instrument patch)
* fixed minor issue with null/silence samples (those stole voices even though they don't need a voice at all which resulted in "voice stealing didn't work out" messages)
* volume of release triggered samples now depends on note-on velocity, note length and gig parameter "release trigger decay" instead of note-off velocity.
* hand-crafted assembly optimization code can be disabled with './configure --disable-asm' (definitely not recommended)
* support for the gig parameters for "release velocity response" curves, which means the decay and release times now depends on velocity. The softer velocity, the longer release. * fine tuning of the envelope curves. Decay1 and release now have two parts, first linear and then exponential at the end.
* (re)implemented voice stealing algorithm "oldestvoiceonkey" and made it the default voice stealing algorithm * added new LSCP command "GET SERVER INFO" which currently returns description and version about this sampler * added some API documentation comments * minor cleanup
* All compile time options are now centrally alterable as arguments to the ./configure script. All options are C Macros beginning with CONFIG_ prefix and will be placed into auto generated config.h file.
* spawning layered voices now within a loop instead of recursively (fixes segmentation fault under heavy voice count load and reduces stress on the stack) * voice stealing operates on all engine channels now * limit voice stealing to MAX_AUDIO_VOICES thefts per audio fragment cycle * fixed keygroup handling (layered voices could kill each other)
* 24-bit decompression now supports the 20 and 18 bit formats * support for "random" and "round robin" dimensions * removed a warning printout for empty samples during instrument loading
* fixed a bug that sometimes caused clicks at the beginning of samples * added denormal number elimination for CPUs with SSE2 support
* design change: using now one sampler engine instance and one disk thread instance for all sampler channels that are connected to the same audio output device (and are using the same engine type of course) * added EngineFactory / EngineChannelFactory to remove the annoying build dependencies e.g. of the lscpserver to the actual sampler engine implementations * bumped version to 0.3.0 (current CVS state is still quite broken, previous, stable CVS version was tagged as "v0_2_0" and is also available as source tarball)
* added support for sample parameter 'attenuation'
* some fixes regarding the filter (fixes the "silence" bug which occured occasionally, caused by random biquad parameters which lead to unstable filter equation and thus to infinit filter output results)
* bunch of fixes for OSX (patch by Stephane Letz)
* support for keyswitching * ignore if no sample was defined for region(s) or dimension region(s) (patch by Andreas Persson)
* another crossfade fix (honoring AttenuationController for case 0,0,0,0, fixed cases in_start = in_end = CrossfadeControllerValue, fixed curve for cases out_start < CrossfadeControllerValue < out_end, honoring InvertAttenuationController parameter) * support for up to 8 dimensions as introduced by Gig V3 (patch by Andreas Persson)
* Fixed pitch calculation. FineTune needs to be taken as is without multiplying it by 10.
* Initialize the synthesis mode bitmask properly
* fixed endless loop at the end of sample playback (patch by Andreas Persson)
* Added some profiling capabilities, bugs.
* Applied patch from Andreas Persson and made a few other small changes to fix a bug in the filter code.
* fixed bug which caused samples not to be played back to their actual end (patch by Andreas Persson, added a small extra fix)
* fixed CalculateBiquadParameters() to set parameters for both right and left, not just left.
* 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
* Small fix to pan coeff. calculation. * (LS was silent with gigs where pan was 0).
just tidied up event type specific parameters (that is note-on specific parameters, controle change specific parameters, etc.) in Event class
* support patch panorama info
* 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 crossfades * support sample playback start offset
* added support for layers * fixed initial pitch calculation which did not honor the sample's own sample rate
* src/engines/gig/Voice.cpp: dimension region selection takes current MIDI controller values into account
* 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)
* LSCP allows now comment lines, that is lines starting with a hash ('#')
character
* src/engines/gig/Voice.cpp: fixed "SET CHANNEL VOLUME" bug
forgot to remove a redundant assignment (only a small efficiency issue)
* 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)
* src/Sampler.cpp: fixed 3 stupid but fatal bugs that left in the rush (in
method SamplerChannels(), CreateAudioOutputDevice() and
CreateMidiInputDevice())
* src/network/lscpserver.cpp: implemented LSCP command
'SET CHANNEL MIDI_INPUT_CHANNEL'
* src/Sampler.h: moved enums 'audio_output_type_t', 'midi_input_type_t'
and 'engine_type_t' into the respective base classes
('AudioOutputDevice', 'MidiInputDevice', 'Engine')
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
