Rotary controller design

Input:

• midi
• clock signal
• cv in? (to control parameters) - for 4 channels
• audio in? (maybe for tuning or finding out a chord?)

Output:

• midi
• clock signal
• trigger/gate CV for 4 channels
• audio out

Controls:

• Dial to control steps/pulses/offset per voice (4x)
• Up/Down or keyboard for extra control? Adding parameters?

Displays:

• Display for the dial (4x)
• Display for extra information

Two modes:

• Rhythm generator
• Chord finder

Rhythm generator is pretty obvious, with the euclydian rhythm generator

• Number of notes
• Number of hits
• Offset
• Fill Probability (for extra hits) -> may be evenly distributes with “secondary” rhythm?
• Swing (global setting)
• BPM (global setting)
• Hit volume / Fill volume

Chord finder:

• key (root note)
• chord number
• flats / sharps OR mode
• Actual chord

(there’s a relationship between these values, so changing one value, with result in a change in other values!) (also need something with other kinds of chords - sus, 7th, 9th, etc) (and what about slash chords?)

Also need the option for borrowed chords:

• From the parallel minor (or actually - parallel mode… - mostly major vs minor)
• Secondary dominants: the dominant chord of another chord
• Other possibilities: ii of a chord, or IV of a chord…
