* 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
* Added MISCELLANEOUS event to help debugging client/server interaction. It spits out every line received by the server.
* 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.
* Unconsolidaded MIDI input related channel commands are back: SET CHANNEL MIDI_INPUT_DEVICE <chan> <midi-device> SET CHANNEL MIDI_INPUT_PORT <chan> <midi-port> SET CHANNEL MIDI_INPUT_CHANNEL <chan> <midi-chan> * Still useful for compability with legacy clients, an almost deprecated command gets re-implemented: SET CHANNEL MIDI_INPUT_TYPE <chan> <midi-driver> * Optional parameter list on MIDI input device creation fixed, but not quite fully effective yet: CREATE MIDI_INPUT_DEVICE <midi-driver> [<key>=<val>...]
* 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.
Cleanup for GCC bug workaround
* Fix for CREATE_AUDIO_OUTPUT_DEVICE with all default params * Fix for GET AUDIO_OUTPUT_DEVICES resultset * Support for BACKGROUND loading
* Changed LSCPServer::LoadInstrument() signature, which adds a new boolean argument (bool bBackground) where the loading mode maybe selected, whether modal (the default), or modeless (in background).
* Update parser to comply with the latest spec
* 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
* 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
* 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
