The resonance of the low pass filter can get pretty wild at high settings, creating growling filter tones or sine wave oscillation. Both filters include CV control, plus the low pass filter features a 1V/oct input for tracking along with sequences. The VCA comes after the filter and features initial level and exponential CV control. Eudemonia brings together mixing, filtering, and volume control in one package with simple but intuitive controls.
This synth is lightly used and works great. It'll ship out the next day with the original box.
