An analogue oscillator with through-zero phase modulation. The core of the T-ZED is the SSI2130 integrated circuit. Voltage controlled wave shape and phase modulation index allow for automated sonic versatility, and 2 separate frequency ranges mean the T-ZED can be used as an audio or CV source.
MACA is a 4-pole multimode filter based on the SSI2140 (SSM2040) integrated circuit. Besides the obligatory 4-pole low pass, MACA adds both 2-pole low pass and 4-pole band pass outputs. There is also a input level control that allows you to easily overdrive the filter core.
LR4 is a three-way crossover under voltage control. Two four-pole state variable filters in series allow an input signal to be split into three non-overlapping bands, while the fourth-order Linkwitz-Riley slopes provide ideal band separation. And because both filters are full range, the bandwidths are arbitrary, not range-restricted.

WFM Oscillator is an analog VCO with a unique wave shaping circuit. Based on the 1970s Kobol synthesizers, the WFM output provides a continuously variable waveshape from triangle to saw to modulated pulse, with many interesting points in between. Voltage control over waveshape and output amplitude allow for wide timbral variations.
