Bit 7 is Delay Treble Rolloff (active high)
Bits 6-0 are L/R delay time separation, 1-25
High nib controls function of TAP footswitch:
0000 = Tap Tempo (default)
0001 = EFX mode status reset (from preset)
0010 = <reserved>
0100 = <reserved>
1000 = <reserved>
Multiple 1's flags toggles to the corresponding
bits in the low nibble. Examples:
0101 = Toggles boost and delay mode
1110 = Toggles all effects, but not boost
etc. etc.
Low nib is EFX mode status:
Bit 0 is Boost (on/secondary = high)
Bit 1 is Modulation (on/secondary = high)
Bit 3 is Delay (on/secondary = high)
Bit 4 is Reverb (on/secondary = high)
