Notes The intellijel dr. octature, another installment in the David G. Dixon 2164 series of modules.

The basis of the module is a 4-pole lpf inspired by the classic “cascaded ota” design, but realized instead with superior-quality 2164 vcas.

The “octature” refers to the 8 distinct, phase separated outputs (every 45 degrees, or two sets of four 180-degree shifted outputs). each pair has a different slope: 6db, 12db, 18db and 24dB.

The cascaded-stage design is similar to the filter found in absolute classics such as the roland jupiter-6 and sh-101. However, when put into self-oscillation this filter becomes a stable, 1V/Oct tracking LFO/VCO, with each of the 8 outputs giving a sine wave 45 degrees out of phase with the next.
