TherapSID with ASID support & performance controls (Plays C64 SID tunes)

Since the Twisted Electrons TherapSID firmware is now open source, I have implemented some enhancements to my unit, adding "ASID" protocol support and performance controls, showcased here. ASID was originally developed as a way of sending Commodore 64 SID files over MIDI to be played back on the Elektron Sidstation.

NOTE: This is now included in the official TherapSID 2.3 firmware - and a browser player has been added to DeepSID. See this one for demo of finished stuff:    • TherapSID - more ASID and DeepSID support ...  

First few minutes shows the features, then follows some full SID songs. This TherapSID is equipped with two 6581 SIDs, a bit panned to give a stereo effect.

Features:
ASID playback on the TherapSID.
The Voice LEDs lights up to show what waveforms and sync/ring mod states are used
The LFO LEDs are used to indicate filter status:
LINK 1, 2, 3 indicates that the voice is routed to the filter
Waveforms indicate the cutoff frequency as a 5-stage amount
RETRIG/LOOP indicate the resonance level as a 2-stage amount
Moving knobs and pushing buttons enables performance and remixing of the SID file
Waveform SHAPE button mutes/unmutes the channel
CUTOFF, RESONANCE, ADSR etc affects the corresponding parameters
Short press on RESET restores all remix modifications
Long press on RESET takes the unit out of ASID mode and goes back to normal

Note: this is a proof-of-concept implementation, not available in the current official firmware.
