MIDI

MNodes has comprehensive MIDI support for both receiving and generating MIDI data.

MIDI Input

Plugin Mode

MIDI from your DAW is received automatically through the MIDI In node. All MIDI data on the track (notes, CC, pitch bend, clock) is passed through.

Standalone Mode

Select your MIDI input device in Settings → Audio/MIDI. Connect a MIDI controller and it will feed into MIDI In nodes.

MIDI Routing

A typical MIDI-controlled synth patch looks like:

MIDI In → MIDI To CV → [Pitch CV] → Oscillator (Freq input)
                     → [Gate CV]  → Envelope (Gate input)

Envelope → VCA/Gain → Filter → Audio Out

MNodes handles all standard MIDI messages:

• Note On / Off:Trigger oscillators and envelopes
• Pitch Bend:Modulate pitch
• CC (Control Change):Map to any parameter
• Clock:Sync tempo and sequencers
