Hello,

I had found a Picture from TB-303 Chord Wheel! It is nice.
How does one use this wheel? Me can someone show that?
Can thank you make an example for me?

You're going to need at least 3 TBs to actually play a chord though.

This is pretty simple. Each wheel just goes chromatically upwards as you go clockwise. Comparing one wheel to the other gives you a transposed key vs. the original key. On a synth, you have some control that does the pitch shifting automatically, and then the outside wheel represents the original note while the inside wheel represents the shifted one. For a non-synth example, say you wrote a score in concert pitch, and wanted to convert one part for an Eb horn. You'd set the wheel to D#/Eb. Find the note from your concert score on the inside wheel, and the note on the outside would be the correct note to write for the horn part.
