Sticky Revision: |
* another voice stealing fix (endless loop occured when voices were stolen from other engine channels)
* LSCP server: fixed LSCP event "CHANNEL_INFO" notification (e.g. did not notify on volume changes)
* don't reset scale tuning on instrument or audio output device change
* revised voice stealing (fixes crash caused by voice stealing)
* volume of release triggered samples now depends on note-on velocity, note length and gig parameter "release trigger decay" instead of note-off velocity.
* 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.
* removed some build warnings * fixed a bug with hanging notes when using sustain pedal * release samples are not triggered anymore when sustain pedal is down
* fixed MIDI GS scale tuning (via SysEx Message)
* fixed segmentation fault on "GET CHANNEL INFO" commands which occured when an engine type was selected but no audio device connected yet to the sampler channel (fixes bug #4)
* fixed event leak (events sent to inactive keys were not freed) * implemented MIDI channel mode messages "All Sound Off", "Reset All Controller", "All Notes Off" (fixes bug #5)
* fixed another crash under heavy load which was accidently introduced with the previous commit - events have to be processed completely on all engine channels before audio is rendered (fixes bug #7)
* 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
* implemented MIDI Control Change 7 (Volume) * implemented MIDI Control Change 10 (Panpot)
* fixed some segfaults (which occured on EngineChannel destruction) * InstrumentResourceManager: recache small samples if their current number of silence sample points are not sufficient enough for the used audio output device * src/linuxsampler.cpp: voice / streams statistics on the console is back again (can be turned on with command line switch --statistics)
* gig::Engine: fixed silence (engine channels' events were not imported into the engine, fixed undesired creation of new gig::Engine instances (and disk threads) * AudioOutputDevice: reverted behavior to render per Engine instance (and not per EngineChannel instance)
* 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)
* fixed possibility that memory got not locked * immediately set instrument status when calling LOAD INSTUMENT NON_MODAL
* Added INSTRUMENT_NAME to GET CHANNEL INFO command result set
* 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)
* fixed some memory leaks (patch by Gene Anders)
* Fixes for engine reloading. Fixed streaming bugs in some cases only, most probably not all yet.
* 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)
* gig::Engine: changed way how events make it from the input event queue into the engine's process chain (fixes forced segfault in EGADSR) * Event.h: using signed type for fragment position for easier differentiation if event might happened before or after current fragment
* 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
* 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
just tidied up event type specific parameters (that is note-on specific parameters, controle change specific parameters, etc.) in Event class
* 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.
* src/common: added template class 'optional<>' which can be used e.g. as return type whenever a value might be returned, but don't has to; this template class pretty much acts like a pointer of the given type, but is much more safer than a simple pointer * src/audiodriver: added static class AudioDeviceFactory to create audio devices at runtime by using a string and to obtain driver informations of drivers at runtime, driver classes should simply use the macro REGISTER_AUDIO_OUTPUT_DRIVER(DriverName,DriverClass) in their cpp file to register the driver to LinuxSampler (no changes needed anymore in the LS code to add a new audio output driver) * src/drivers: added classes to dynamically manage driver parameters; there are two different kinds of parameters: parameters which are need to create a new device (DeviceCreationParameterX) used to e.g. create an audio output device or a MIDI input device and parameters which are only available at runtime, means when a device is already created (DeviceRuntimeParameterX) which will be e.g. used as audio channel parameters and MIDI port parameters * src/linuxsampler.cpp: all registered audio output drivers will be shown on the console on startup * src/network: implemented configuration of audio output devices via LSCP
* 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)
* 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
