[sdiy] MIDI HD

[Richie Burnett]

That seems strange. The juno 106 filter covers 20Hz to 20kHz, which is roughly 10 octaves or 120 semitones. So with a 7-bit controller exhibiting 128 discrete step, each setting should be roughly a semitone apart. Such a pitch interval is easily perceptible to musician or non-musician! And indeed this seems to show up in practice if you put a synth's filter into self oscillation and manipulate the cutoff frequency over MIDI.  Big pitch steps around the semitone size, sometimes smoothed slightly depending on the synth, but nevertheless big interval steps and coarse control resolution. I agree that this is the one place where MIDI's basic 7-bit type of CC message starts to sound inadequate.
