Playing Tips
Play legato in the C1-C2 range to activate the glide between notes. Harder playing opens the filter more (velocity on filter = 40). Try it with the sequencer: Seq 1 Dest = OAF, program 36, 36, 48, 48, 43, oFF, 46, 36, Step 9 = rST, BPM = 130, Clock Divide = 16th.

Technique Notes
The acid sound depends on three elements working together: high resonance (70) creates the characteristic squelch at the cutoff frequency, strong filter envelope (Env Amount 80 with fast Decay 45 and low Sustain 5) produces the sharp downward sweep on each note, and glide (30) creates slides between legato notes. The Osc Slop at 3 adds vintage analog instability. Distortion at 15 adds subtle edge without overwhelming the filter character.
