Rene Stange	7519da5e13	Fix Stereo channel swap with HDMI (#52) ... There has been a swap of the Stereo channels with HDMI. With the new option "ChannelsSwapped=0|1" in minidexed.ini one can swap the channels again, in case it is needed.	3 years ago
Rene Stange	d6025f1943	Support multiple Dexed instances (#50) ... * dexedadapter: Protect setSustain() with spin-lock too * Initial support for multiple Dexed instances * Currently 2 similar instances, which work with the same parameters * Only 1 instance with max. 8 notes polyphony on RPi 1 * Chunk size needs to be increased on RPi 1 * Support 8 Dexed instances (TGs) with multi-core * Core 1 kicks core 2 and 3 and processes two TGs then * Cores 2 and 3 wait for a kick and process three TGs each then * When all cores are ready, the output will be summed up * All 8 TGs generate the same sound at the moment * The maximum chunk size is limited to 4096 now * Maintain voice bank number per TG * Support TG select in UI * Active TG number is shown on LCD display * Next TG is selected by double click * MIDI receive and PC keyboard are still in omni mode * pckeyboard: Fake MIDI events * on MIDI cable 0, channel 0 * instead of calling key[down|up]() * derive from class CMIDIDevice * ui: Precede screen messages with TG number * Configure MIDI mapping from UI * ui: New menu item "MIDI" for configures assigned MIDI channel * ui: Holding switch for at least one second returns to menu home * ui: Do not show TG instance, if there is only one * By default TG1 is in omni mode, all other TGs are not assigned * config: Default chunk size is 1024 without multi-core	3 years ago
Rene Stange	7707f90d46	Add initial optional rotary encoder support (#40) ... * Add driver for KY-040 rotary encoder This driver has been taken from the Circle develop branch and can be removed here, when the driver made it up into a circle-stdlib release. * Add initial optional rotary encoder support * Can change between voice and bank select mode by clicking the switch * Turn the knob to select the voice or bank according to current mode * Hold the switch for 3 seconds to reboot the system * Program change from MIDI is only displayed in voice select mode * Configuration for KY-040 added to CConfig and minidexed.ini * Fix: m_I2CMaster has not been initialized in CKernel	3 years ago
probonopd	c9c33ce79c	Update pins for LCD RS and RW ... https://github.com/probonopd/MiniDexed/issues/38 Thanks @rsta2	3 years ago
Rene Stange	8be0781b49	Restructure code and add new features (#37) ... * Make synth parameters configurable * Add class CConfig, which holds the configuration * Add template config file minidexed.ini * Register panic handler in CKernel to allow to display assertions * Fix: Performance timer did not show correct percent value with HDMI * Add class CDexedAdapter Some Dexed methods require to be guarded from being interrupted by other Dexed calls. This is done in the class CDexedAdapter. * Add class CUserInterface The user interface should be implemented here. As a start it supports showing the program number and name on the LCD display. The LCD output is buffered, so that LCD writes from an IRQ handler are possible. * Move MIDI handling from CMiniDexed to specific classes * CMIDIDevice is the generic MIDI handler * CMIDIKeyboard handles USB audio class MIDI devices * CSerialMIDIDevice handles the serial MIDI device * Now all MIDI inputs can work simultaneous * Program change and bank select work with serial MIDI * Add headers to all files * Include voices.c in sysexfileloader.cpp * Cleanup Makefile * Support headless operation on Raspberry Pi 4 Some code cleanup for src/kernel.* * Code cleanup for src/minidexed.* Move implementation of constructors to minidexed.cpp Reorder member variables * Support multiple USB MIDI inputs at once * Maximum 2 inputs on Raspberry Pi 1-3 * Maximum 4 inputs on Raspberry Pi 4 * Suppress frequent messages in MIDI dump * Use minidexed.txt * Document `SoundDevice` in `minidexed.ini` Co-authored-by: probonopd <probonopd@users.noreply.github.com>	3 years ago
