Feels like something that should perhaps be obvious (given I can’t find any other documentation/discussion on the web of how to do it), but how exactly do you select the channels of a multi- channel USB audio source for the OP-1 field? The (now fairly old) update 1.5.6 included the “option for selecting input channel(s) on usb audio”, but when connected via USB-C to a TP-7 with multi-track audio playing the OP-1 field (updated to the current version 1.6.5) does not present me with an obvious option when selecting the USB audio from the input selection screen. I thought the ochre encoder would do something here, but it does not do anything–despite that this should mirror the instructions available for how to do this on the op-xy.

You’re correct that the ochre encoder should select which mono or stereo USB input your OP-1f receives. Once connected, the text below the USB input will change to something like “USB 1+2” if it supports multichannel. If the OP-1f doesn’t detect multiple channels it’ll only say “USB” below the input.
Note: OP-1f’s multichannel function doesn’t work with all USB audio so there’s a chance that’s the issue.
Yea, thanks for the sanity check, and yea, because it only says “USB” below the icon, I guess I have to conclude the OP-1f is not detecting multiple channels, despite that I tested this on the TP-7 both against a recording with manually created multiple channels/tracks, as well as, creating a recording with the TP-7 that was fed both tracks simultaneously from the multi-channel USB audio output from the OP-1f (and so I can fully confirm on the TP-7 that the audio source has multi-channels/tracks). Selecting channels from multi-track audio from TP-7 should be a thing that works–so I guess I will file a bug with the TE team.
