MIDI controlled SID, was flying faders, was [sdiy] keyboard resources

Still think he got a point.
Interfacing knobs to a C64 is quite easy.
There are even 2 (or was it 4??) inputs for potmeters already there, the
game paddle connections.

On the other hand, the C64 has no midi, so you have to interface the midi
I/O.
If memory serves there is a small problem getting the correct baud-rate for
midi.
30.000 baud v.s. 31.250 like it is supposed to be.
Don't remember why this was, the CPU is 1mhz so this should be a suitable
clock source for the correct midi baud-rate.
