A 4-pole multimode filter based on the SSI2140 integrated circuit. Essentially an updated version of the classic SSM2040, the new SSI2140 adds better temperature compensation and a VCA that helps eliminate low frequency damping at high resonance settings. Besides the obligatory 4-pole low pass, MACA adds both 2-pole low pass and 4-pole band pass outputs. There is also an input level control that allows you to easily overdrive the filter core.

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.
