Compact oscillator module with envelope generator and filter.
The Mr. Phil Ter module features an envelope generator and a filter for a variety of analog and digital sounds. The digital side houses the envelope generator while the analog side is comprised of a voltage-controlled amplifier circuit as well as an extra juicy old-school transistor ladder filter. Pair Mr. Phil Ter up with any oscillator or crank up its own filter section's resonance and self-oscillate.
