Trace is a four-channel Interpolating Scanner created in collaboration with Ben Wilson “DivKid”.
Introduced by Jurgen Haible in 1994 and later improved by Donald Tillman in 1999, the Interpolating Scanning circuit is a hybrid between a signal selector and a crossfader. 
The circuit morphs between the inputs, fading from one to the next as the voltage control rises. The Trace version of this classic circuit comes with a custom, fine-tuned slope response that prioritizes a smooth transition between the inputs, providing interesting middle points between the channels and improving its behavior when controlled by external CV signals.
Following Ben’s unique vision and module design, Trace unifies the compact form that characterizes his modules with our hardware and aesthetics. 
From waveform morphing and CV-controlled transitions, to audio-rate scanning. Trace brings a new horizon of patching possibilities to any system.
