Add also the famous 4 VCF filters sliders controlling 2 Highpass and 2 Lowpass cutoffs, with 3 steps selectable resonance and VCA mod. On top of that, you have a Pulse LFO allowing to repeat triggers in 5 different modes, like two voices at the time, voices alternating for pulsing leads, ajustable speed and Decay.

You also have two switches for controlling the playing mode, choosing which voice plays when one key pressed, or two key pressed.

You have access to individual voice volume control and independent audio outputs.

The keyboard is extremely stable, without drifting over time, and easy to tune."
