The Intellijel designs - Dr. Octature II. is based on the Mankato VCF. A special filter design which featured 4 filter types with their traditional and their inverted outputs. Once you take this filter to self oscillation and dial down the cutoff frequency, you will end up having an LFO with not 4 stages of outputs fading in and out after one another, but eight(!) stages. It is a simple yet ingenious idea and can create a lot of interesting modulation patterns in your system!
Intellijel designs - Dr. Octature II
Just like the original Dr. Octature 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 sound is very reminiscent of classic Roland filters such as the one found on the SH-101 or Jupiter-6.
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.
This is filter was designed by David Dixon with a special resonance distribution mode called “QUAD” that results in an especially fat and warm LPF sound that is consistently balanced with respect to the resonance on all 8 outputs.
When oscillating this filter becomes an excellent clean sine wave VCO capable of tracking over several octaves. It can also operate in LFO mode where the phase shifted outputs become extremely useful for creative modulation. Use it to make your Planar spin in circles for example!
New in this version is an input soft clipping circuit to help warm up and boost sounds before filtering them.
