You suggest three approaches: (1) no change, accept some mistuned chords, (2) shift pitch, or (3) let the tonic wander. In answer to how does Justonic deal with this issue: we allow all three. The Justonic approach is to not dictate how a musician should deal with this, but rather to give as many options as possible. With our system: (1) a KEY change modulates the key tonal center. (2) a ROOT change identifies the tonal center within a key and always in relation to the key (that is, a second ROOT change does not modulate from the notes of the current harmony, but from the original key tonal center). (3) NO ROOT CHANGE means that all tones retain their ratio value to the key tonic, and therefore may result in mistuned harmonies, wolf notes, etc. (4) A fourth option is a SCALE change which can also happen in real time, and can result in any "note" being assigned any ratio (pitch) at any time. Where we go from here is to extended scales, non-octave scales, or anything a composer or musician wants to do. If musicians and composers can articulate to us what they want to achieve, we will attempt to build it into the Justonic system. We absolutely do not believe instrument designers should be in the business of dictating how music should be played. That's why we got into this, to create instruments that actually served musicians and placed all parameters at their fingertips. The Justonic Tone Palette additive synthesizer does the same with timbre, giving musicians precision and flexibility with both pitch and timbre. It's a long road, but that's our vision. We have Ling Lun, Pythagoras, Zalzal, Zarlino, Mersenne, Helmholtz, and a long line of others beind us (or above us) encouraging us forward. Please forward any ideas or questions. Cheers.
