Hi DSP developers,Working on a 342-frequency microtonal synthesizer based on Enneagram Tritype mathematics.
The system uses 162-EDO (Equal Division of Octave) tuning - not 12-TET.
Frequency Generation:
- 27 Enneagram Tritypes × 6 permutations each = 162 core frequencies
- Plus derived layers (binaural offsets, DNA Bridge correlations) = 342 total frequencies
- Example: Guardian Angel (126) → 126, 162, 216, 261, 612, 621 Hz
- Golden Ratio alignment: 126→162 Hz (φ proximity)
Technical Implementation:
- MPE (MIDI Polyphonic Expression) for per-note pitch bend
- Current: Browser-based MIDI synth
- Next: VST with 162-EDO tuning tables
Challenge: Calculating pitch bend (in cents) for 342 unique frequencies across standard 12-TET MIDI.
Currently using: (1200 × log2(target_freq/ref_freq)) cents offset.
Open Science: All 342 frequencies and mathematical proofs on Zenodo (DOI: 10.5281/zenodo.19221418)
Questions:
1. Efficient microtonal tuning table implementation in VST3?
2. Handling MPE pitch bend range for 162-EDO divisions?
