aether-midi

MIDI engine for AetherDSP — device routing, clock sync, and microtonal tuning.

Features

• MIDI device routing — connect hardware controllers to graph nodes
• MIDI clock — sync BPM to external MIDI clock source
• Tuning tables — 17 microtonal tuning systems including all 7 Ethiopian qenet modes (Tizita major/minor, Bati minor/major, Ambassel, Anchihoye), Arabic maqam (Rast, Bayati, Hijaz), Indian raga (Yaman), Gamelan (Slendro, Slendro Stretched, Pelog), and Just Intonation (5-limit, 7-limit)
• Event system — typed MIDI events (NoteOn, NoteOff, CC, PitchBend, Clock)
• JUCE Integration — Use these tuning systems in C++ JUCE plugins via aetherdsp-juce-bridge

// Gamelan

// Just Intonation
let ji_5 = TuningTable::just_intonation(); // 5-limit (traditional)
let ji_7 = TuningTable::just_intonation_7_limit(); // 7-limit (blues, barbershop)

// Standard Western
let tet = TuningTable::equal_temperament(440.0); // 12-TET

// Custom — provide your own frequencies
let custom = TuningTable::from_frequencies(vec![...], "My Scale", "Description");
