Properties

Signal chain: MIDI → a Voice per Key (16', 8' and 4' PolyBLEP Sawtooths, locked an octave apart, free-running) × Attack/Release Envelope → Sum → 12 dB/oct Low-Pass (Brightness) → Body Resonances (450 Hz, 2.8 kHz) → Three-Tap Ensemble (slow and fast LFOs, 120° apart; mod wheel deepens it) → Volume. Fully polyphonic like the divide-down originals, no samples; sustain pedal, pitch bend ±2 semitones, all MIDI passed on.
