An expression to convert Pitch to MIDI note number
  • This might well have been mentioned elsewhere but I thought I'd share this useful method to get MIDI note numbers from the keyboard module:

    - connect the keyboard Hz output to the input of a Math/Expr module
    - for the expression, use: 69+12*log2(x/440)
    - the output of the expression will be the MIDI note number corresponding to the frequency.

  • Now, if only Audulus could transmit this MIDI note number, and other MIDI parameters, via MIDI to external recipients!
