Intellijel Designs Dr Octature

Product Description:
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.

features:
- 14 HP
- coarse and fine tuning
- range switch for lfo (0.017Hz to 300Hz) and vco (17Hz to 22kHz) modes
- vc resonance with logarithmic response for smooth control
- 1v/oct temperature stable tracking
- mono/quad resonance gain distribution switch for classic or enhanced performance
- unipolar fm1 and bipolar fm2 attenuated CV inputs
- single pcb design (very shallow/skiff friendly)
