Analog synth from the 80’s with two DCOs, three EGs, a 24db/oct filter, chorus. A popular choice for modification.
Filter resonance is set pretty high while the cutoff is modulated dramatically with an envelope. Starts out sounding like a percussive sound, then evolves into a pad-like sustain.
Sonically dense and dark gradually expanding in tone to become bright. Makes for an interesting base to build upon.
