WatKat is a digital clone of a Wem Watkins Custom Copicat tape echo unit.

It sounds very lo-fi, noisy, irregular. When you turn it off and leave the tape loaded, the tape bends in proximity of the capstan, and this turns into a periodic pitch fall during echo playback; plus, it gets hot and the background hum gets worse in time… you should turn it off every now and then; the tape is never completely erased, and the capstan motor flutters… and it gets worse if you touch it while it's spinning; heads tend to get dirty very soon, in fact you should clean them often. This is true for the actual hardware unit, and for the digital simulation as well!

  • Swell: adjusts the volume of the repeats.
  • Sustain: adjusts the number of repeats; be careful with this knob!
  • Gain 1: volume of input 1 (left channel).
  • Gain 2: volume of input 2 (right channel).
  • Head 1, Head 2, Head 3: use these switches to select the playback head(s); each head gives a different delay time.
  • Very light on CPU and memory.
