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`

Fix: Invalid handling of .syx file indexes ( #34 )
...
Indexes of voice banks are zero-based now in any case (for the user
and internally). In CSysExFileLoader::Load() do not decrement file
index any more to calculate internal voice bank index. Do not
increment internal index, when generating user messages.
