* support for muting sampler channels and solo mode of the same, two new LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were introduced for this (patch by Grigor Iliev, a bit adjusted)
command syntax (BNF) of LSCP specification is now auto generated
* (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
* Little LSCP API change: renamed events "CHANNELS" -> "CHANNEL_COUNT" and "INFO" -> "CHANNEL_INFO" to be more meaningful (patch by Grigor Iliev).
* tiny fix in LSCP parser; returned prefix "Err" instead of "ERR" on syntax errors (patch by Grigor Iliev)
Rui forgot to commit this file with previous commit batch
* JACK audio driver: fixed handling of channel parameter 'JACK_BINDINGS' * fixed parser bug of multiplicity parameters
* 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 first cut of instrument database query support.
* MidiInputPort: fixed dispatching of MIDI events to engines which are listening to all MIDI channels * switched MIDI channel indexing to low level indexing (means 0..15 now)
* src/network/lscp.y: fixed symbol 'midi_input_channel_index' to allow keyword 'ALL' for the respective LSCP commands
* ALSA MIDI driver: create one MIDI port by default, implemented parameter info for parameter 'ALSA_SEQ_BINDINGS' * ALSA audio driver: implemented parameter info for driver parameters 'FRAGMENTS' and 'FRAGMENTSIZE' * JACK audio driver: fixed creation of channels on device creation, channel parameter 'NAME' now actually updates the respective JACK port name, implemented channel parameter 'JACK_BINDINGS' (as well as its parameter info) * src/network/lscpserver.cpp: fixed commands "GET MIDI_INPUT_DRIVER_PARAMETER INFO" and "GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO", fixed backward compatibility for "SET AUDIO_OUTPUT_TYPE" and "SET MIDI_INPUT_TYPE" commands * src/networ/lscp.y: added comma character (',') to symbol 'char' * src/drivers/DeviceParameter.cpp: fixed methods RangeMin(), RangeMax() in class DeviceCreationParameterInt which returned wrong values
* 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)
* src/drivers/midi/MidiInputDeviceAlsa.cpp: implemented port parameter "NAME" which now updates the registered ALSA seq port name as well, fixed port parameter "ALSA_SEQ_BINDINGS" to allow more than one binding * src/network/lscp.y: fixed symbol STRINGVAL (that is strings encapsulated into apostrophes) which didn't allow space characters * changed all driver names and driver paramaters to upper case * fixed typo in LSCP documentation (section 5.3.12, was: "SET MIDI_INPUT_PORT PARAMETER", should be: "SET MIDI_INPUT_PORT_PARAMETER")
* completely removed the lex scanner and replaced it by pure yacc rules for all terminal symbols (that is command keywords and variables) to avoid misunderstandings while parsing (e.g. recognition of command keywords in string arguments) * src/drivers/audio/AudioChannel.cpp: changed channel parameter 'Name' to 'NAME' as defined in the LSCP documentation
* src/drivers/DeviceParameter.cpp: fixed return values for classes 'DeviceRuntimeParameterString' and 'DeviceCreationParameterString' which returned their values without being encapsulated into apostrophes, fixed return values for 'DeviceRuntimeParameterBool' and 'DeviceCreationParameterBool' to be returned in lower case (as defined in the LSCP documentation) * src/network/lscp.y: key value pairs now also allow strings (without spaces) to be not encapsulated into apostrophes (e.g. foo=bar instead of foo='bar') * src/linuxsampler.cpp: show on the console which TCP port the LSCP server is using
* introduced and implemented new LSCP command "RESET" which resets the whole sampler instance * src/drivers/audio/AudioOutputDeviceAlsa.cpp: parameter 'card' now returns all available sound cards as possibility, added dependency to parameter 'card' to parameters 'fragments' and 'fragmentsize' * src/drivers/DeviceParameter.cpp: fixed return value(s) for classes 'DeviceCreationParameterString' and 'DeviceCreationParameterStrings' which returned the default value(s) not encapsulated into apostrophes * src/network/lscpserver.cpp: fixed implementation of LSCP commands "GET MIDI_INPUT_DRIVER_PARAMETER INFO" and "GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO"
* implemented "SET ECHO" LSCP command
* src/Sampler.cpp: changed sampler channel index allocation from consistent channel index allocation to incrementing channel index allocation, that is it doesn't fill channel index gaps anymore (to avoid race conditions) * implemented "LIST CHANNELS" LSCP command
* GET MIDI_INPUT_PORT_PARAMETER INFO command
* moved ToString to common * Implemented handling of multiple connections * Implemented guts for event subscription/unsubscription * Illustrated event notification sending by sending MISC events when connections are established or terminated.
Parser regeneration missed on last commit.
* Updated parser, lscp server and sampler class for new MIDI_INPUT * Minor fixes (and major new bugs) here and there * Consolidated 3 SET CHANNEL MIDI_xxx commands into one: SET CHANNEL MIDI_INPUT
* SET CHANNEL AUDIO_OUTPUT_TYPE <chan> <driver> command is back! creates an audio output device instance of the given driver type ('Jack' or 'Alsa') with default parameters if none exists, otherwise it just picks the first available device and assign it to the intended sampler channel. * The AudioOutputDevice class get's a new pure virtual method, Driver(), which is implemented on both of the existing inherited classes, AudioOutputDeviceAlsa and AudioOutputDeviceJack, with the sole purpose to return the driver type name as a String ('Alsa' and 'Jack', respectively). * The quoting on the filename argument for the LOAD INSTRUMENT command has been made optional; you can have both ways, with single quotes or none, keeping compability with older LSCP specification. * An additional sanity check is made on LOAD INSTRUMENT, whether the sampler channel has an audio output device assigned, thus preventing the server from crashing on instrument file load. * The GET AUDIO_OUTPUT_DEVICE INFO now includes the missing 'driver' item, as predicted by the draft protocol document.
* LOAD INSTRUMENT NON_MODAL
* Fix for CREATE_AUDIO_OUTPUT_DEVICE with all default params * Fix for GET AUDIO_OUTPUT_DEVICES resultset * Support for BACKGROUND loading
* Update parser to comply with the latest spec
* 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
* LSCP allows now comment lines, that is lines starting with a hash ('#') character * src/engines/gig/Voice.cpp: fixed "SET CHANNEL VOLUME" bug
* 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')
* 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
* implemented parser for the LinuxSampler control protocol (LSCP) by using flex / bison (where src/network/lscp.l is the input file for lex / flex and src/network/lscp.y is the input file for yacc / bison), parser and scanner can be regenerated by 'make parser' * implemented LSCP network server (only single threaded so far), LSCP server will be launched if LinuxSampler was started with "--server" flag, implemented the following LSCP commands so far: "LOAD INSTRUMENT", "GET CHANNEL VOICE_COUNT", "GET CHANNEL STREAM_COUNT", "GET CHANNEL BUFFER_FILL", "SET CHANNEL VOLUME" and "RESET CHANNEL" * disk thread now started within the engine
