The side which connects to the audio interface has a quarter-inch TRS (tip - ring - sleeve) jack, the CV-emitting side has a 3.5mm TS (tip - sleeve) jack. The use with DC-coupled interfaces is possible now by omitting the "ring" in between.
Combine with a mono 3.5mm to 1/4" adaptor to give a 1/4" TRS to TS cable.
one side: 1/4" TRS jack (TRS: tip - ring - sleeve)
