* Initial commit for configuration TGs and polyphony across RPI1-5.
* Ensure unused TGs in a performance are MIDI disabled. Set polyphony to higher defaults on Pi 4 and 5.
* Actually, can just default to MIDI "disabled" directly in performance config if not present.
* Fix issue with choosing max polyphony
* First implementation of using four PCM5102 I2S sound devices for 8-channel mono sound output on a Raspberry Pi 5. Requires latest develop branch of circle.
* Update to required develop branch of circle
* Adjusted default chunk sizes to correctly support number of channels.
* Update queue size as per Rene's suggestion.

* Initial build with basic structure to support st7789device once added to circle.
* Implementation of ST7789 display - requires updated circle with new ST7789 character driver.
* Added more details to minidexed.ini about ST7789 and SPI options.
* Update to develop branch of circle that now supports st7789 character mode display.
* Minor formatting fixes to tidy up.
* Allow setting of more advanced SPI parameters: mode and clock.
* Update to allow for font size as an option.
Implements #580
* Initial update in performance file handling. This change makes the 6-digit number in the filename indicate a performance "voice number" in MiniDexed. The external filename numbers will now match any Program Change messages using the common MIDI concept of user selecting 1..128 whilst internally they are treated as 0..127. Note: in the case of performances, performance 1 (index 0) is the Default "performance.ini" file for backwards compatibility.
Also note that in this version, new performances, when saved, cannot occupy free slots between other performances - they are added to the end.
Even though the filename standard gives 6 digit numbers, the actual number of performances is still limited to 256.
* Start of subdirectory implementation for performance banks.
* Initial version with performance banks, selectable over MIDI only.
* Initial implementation of performance bank switching in the UI menu.
* Remove debug information, fix few bugs, including PgmUpDown handling and performance numbers out of range.
* Bugfixes for legacy cases when no performance directory exists plus some extra checks for saving and deleting performances.
* Remove verbose debug options (doh!)
* Fix a minor off-by-one error found in review.
* Bugfix - removed redundant legacy check that results in out of order performance files being skipped on load.
* Fix bug in MIDI button handling commands.
* Fix for issue where wrong performance is selected [L] on new save.
* Suggested update to UI to show bank/performance numbers.
* Make performance bank select asynchronous to MIDI and UI to stop corruptions on loading performances.
* Fix an assert that should be a run-time test.
* Ensure bank selection works when PCCH is not enabled, and that UI remains consistent when changing banks.

* Initial implementation of Program Up/Down and Tone Generator Up/Down selection and short cuts as buttons and MIDI buttons.
* Add configuration option for Program Change to act on Voices within a TG or Performances.
* Added PC option to Performance menu. Various bug fixes. Allow menu updating if on Performance/Load display. Swapped TG1 and TG3 in Performance 000008 so that TG1 is set to MIDI CH 1 in all Performances.
* Minor fixups in formatting and so on after review.
* Formatting fixups
* Changed config setting to match description in original manuals: Performance Select Channel. Also now accepts 1-16 or Omni as values.
* Additional fix to ensure GPIO buttons are working correctly on Voices or Performances.
* Changed initialisation order for PerformanceSelectChannel to avoid asset problem on a Pi 4 and updated menu text to fit nicely on a HD44780 display.

* Saves the performance config to performance.ini
* Comments in an existing file will be overwritten
* Function displays "Completed" and returns to "Save" menu
* Support hierarchic menus
This introduces a new menu engine implemented in the class CUIMenu,
which can be configured with C-tables. This should make it easier to
extend the menus, without modifying the code too much. The UI provides
a main menu, which selects the TG to be edited and a TG sub-menu, which
presents the already known TG parameters (voice bank, voice, volume,
pan, detune and channel). A sub-menu is entered with single click and
left with double click. There are arrows displayed on the LCD, which
show the direction(s), to which the knob can be moved. All TG related
parameters are maintained in the class CMiniDexed now.
* uimenu: Make the tables const
* uimenu: Add sub-menu "Edit Voice"
Menu items can be re-sorted, if necessary.
* uimenu: Add "Reverb" sub-menu
* Map reverb float parameters to range 0 .. 99
* minidexed: Add global (non-TG) parameters
* minidexed: Protect reverb module with spin lock
* Additions for compressor.
* Added code for enabling compressor of Synth_Dexed (with default values).
* First try for adding a reverb effect.
* Fixes for reverb.
* Added full implementation of plate reverb.
* -o KERNEL_MAX_SIZE=0x400000

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.
* 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
* Cleanup Makefile
* Update submodule circle-stdlib to v15.12
* System options can be defined cleaner using the "-o" option
* Include KY-040 driver from Circle (removed from MiniDexed)
* Render sound on secondary CPU core 1
* Enable multi-core support on Raspberry Pi 2-4
* Does still work on the Raspberry Pi 1 with restrictions
* Use CSoundBaseDevice::Write() instead overriding GetChunk()
* CMiniDexed is not derived from the sound device classes any more
* Add option SCREEN_DMA_BURST_LENGTH=1 to relieve bus congestion
* Add volume control to MIDI CC and UI
* Add CPU full speed support
Normally the CPU runs at a reduced speed in bare metal applications.
With this update and the setting "fast=true" in the file cmdline.txt, it
runs at the full speed.

Should result in a smaller IRQ latency on CPU core 0 and in a better USB handling.
It still works on the RPi 1 too, but the MIDI dump and profiling has to be disabled there,
otherwise one will hear drops, when the screen scrolls.

Thanks @rsta2
* 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
* 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`
