Schlappi Engineering Boundary
Super clean unit, includes original box and bus cable.
The Boundary is multi-purpose modulation and signal control center. It consists of a cycling slew and a four quadrant multiplier (VCA).
The cycling slew (which can be used as an envelope or LFO) has individual control over rise and fall, rate and shape, as well as dedicated inputs for trigger, slew (for gates or pitch cv), full wave rectification (for envelope following), and a unique BOUND input which allows for bouncing ball effects and additional modulation of the envelope.
The four quadrant multiplier is an OTA design and is usable as a VCA or ring modulator with a soft limiter on the output to tame extreme signals or push into distortion.
Features:
LFO and modulation oscillator (from cycles measured in minutes to high audio rate)
Envelope following with a dedicated full wave rectifier input so no peaks are lost
Bouncing ball effects using the unique bound input
Voltage controlled frequency division at clock or audio rate
Slew can be used as portamento for v/oct signals
Four quadrant VCA allows for ring modulation
Soft limiter on the VCA output allows for taming or distortion of wild signals
