Vostok Instruments Trace

4-input morphing scanner — interpolates between four sources into one output.

4 HP Eurorack module

Trace is a four-channel analog Morphing Scanner built jointly by Vostok Instruments and DivKid — the conceptual mirror of its sister module Path. Where Path takes one input and routes it across four outputs, Trace takes four inputs and morphs them into a single output. The Scan fader picks which input is currently at the output, with smooth interpolation between adjacent inputs at intermediate positions — no clicking, no hard transitions. CV input plus attenuator and polarity switch round out the controls. Compact 4HP and DC-coupled throughout, so Trace works equally well as an audio crossfader, a CV morpher, or a wavetable-style sound selector.

Features

  • Four-channel interpolating scanner in 4 HP
  • One signal output — smooth crossfade between four inputs
  • DC-coupled throughout — audio and CV scanning
  • Manual Scan fader for hands-on morphing
  • Scan CV input with dedicated attenuator and polarity switch
  • 5 Vpp CV range covers the full scan span
  • Holds at extremes when CV exceeds range
  • Per-input LED indicators show scan position
  • DivKid × Vostok Instruments collaboration
  • 32 mm depth, 70 mA / 70 mA at +12V / -12V
