Introducing 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."
