About this paper
Dmitri Volkov
Dmitri Volkov at Indiana University Bloomington developed Pivotuner, a VST3/AU MIDI effect plugin that enables real-time adaptive pure intonation and dynamic microtonal modulation. The plugin achieves this by introducing an "adaptive tuning center" and converting MIDI to MPE data, providing musicians with dynamic control over microtonal shifts in live performance and sound design.
Key insights
- Dynamic adaptation of a "tuning center" or "key" note enables flexible pure intonation and real-time microtonal modulation, overcoming the rigidity of fixed-pitch systems.
- Converting single-channel MIDI to MIDI Polyphonic Expression (MPE) allows for individual note pitch bend information, which is essential for precise, independent tuning of notes in pure intonation.
- Embracing microtonal modulation as a natural outcome of dynamic pure intonation, rather than avoiding it, unlocks new avenues for musical expression and timbral exploration.
