Moln

Polyphonic subtractive synthesizer

Features

• 2 square oscillators per voice with variable pulse width and pulse width modulation.
• Resonant lowpass filter
• ADSR envelope

Operation

• ENC1 adjusts main output level.
• ENC2 changes filter cutoff.
• ENC3 changes filter resonance.
• KEY2 momentary toggles fine parameter control.
• KEY3 triggers a random note.
• MIDI device plays notes.
• GRID plays notes too.
• ARC changes filter cutoff (ENC1) and filter resonance (ENC2).
