    When you improvise like this, are you able to hear the piece in the selected tuning as you play it? Or do you apply the tuning to the MIDI file afterwords?

    Hi b0b, for what I do in improvisation it is essential to work within the tuning. I hear the next note(s) I want to play or at least a tendency of the direction the music wants to go. I cannot imagine working in 12 and having it translate to 17 equal or Bohlen-Pierce with much success beyond the wildest coincidence. Tuning comparisons, while interesting intellectually, are a good demonstration of what cross tuning a piece does and mostly doesn’t do.

    Hi Chris, are you using a seven note subset of Blue JI in this piece and if so what scale is it? E.g. is it major or minor or something else? John.

    Hi John, if you watch the animated score you can see that I move between C major and G major, but using the alteration as a mode of C. I hope that answers your question.
    Best Regards,
