No I meant is there any way to make the two monos go in together into the audio interface so I can save a slot. Thanks and sorry for the trouble
Unfortunately, each input on your interface is only capable of receiving a single, mono signal. If you attempt to “merge” two inputs (two mono signals, or a stereo pair) into one of your mono inputs, it will sound waaaay funky. When I got my first audio interface for recording my OP, I had to learn the same lesson, unfortunately. Buy that chord Spheric is recommending you! It works beautifully for me and is the only solution to recording into your interface for this configuration (the Microkorg XL + OP-1 using that chord for the OP-1 and whatever the former needs, plugged into your interface, with the OP-Z output plugged into your OP-1 input).
