Put into self-oscillation, the DR.

OCTATURE becomes a stable, 1V/Oct

tracking LFO/VCO.

Sine VCO range : 17Hz to 22kHz (0.059s

to audiorate).

Sine LFO range : 0.017Hz to 300Hz (59s

to 0.003s).

uFade MIX out to Planar CV Y.

uFADE MIX knob controls the rotational direction.

Dr. Octature II CUTOFF frequency controls the

rotational speed, for uFade MIX knob at CW or

A slow sine wave at uFade CV in will make

rotation to slowly change from CW to CCW.
