Ah now would be a good idea. Maybe it could also act kind of like a dongle, in that once connect to the OP-1F it allowed 4 tracks to be recorded at the same time. The OP having extra functions once connected to it.
Obviously said hardware would have to have 4 stereo inputs. The possibilities are endless.
Agreed, or else why release this decade+ old oplab vid on YouTube this week?? https://youtu.be/m00Pf8ZCf7A?si=b1-agiKjje0MRglO
I can’t think of any other reason. They know it will generate speculation about their plans for Superbooth 2025
sorry for the shameless plug – you might dig this track i did all on the op1f wherein i recorded my archtop jazz guitar in with the cm15. this was the first time i ever recorded with the cm15 and so it didn’t turn out as good as it could have - ive learned a lot since then 
but the reason im sharing is bc i read you hadn’t done much guitar into the op1f and this shows a least in some sense how well guitar could be incorporated into a track
Nice work. The guitar came through quite well and the piece is quite unique and musical. I am so tempted to respond the way I see in guitar forums “Sp, did you record direct in or with a mic?”. But I wouldn’t do that here. What I mean is that no matter how clearly you state how you recorded the guitar, somebody will invariably ask such questions. I haven’t seen that around here, fortunately. 
That’s got a nice chilled vibe to it Chris. Well balanced mix which sounds great on my headphones. Definitely a track to chill to whilst having a drink in the sun.
Nice job 
@tbeltrans and @RoyB thank you guys for checking it out and for the kind words! really appreciate it. my basic approach to everything i do on the op1f is to try to get the guitar in somehow someway even if its not the main focus. sometimes acoustic via mic or sometimes electric as line in.
i find that with my electric guitar i actually can just plug it directly into the op1f without anything else in the chain and it sounds great. i do add a bit of gain and FX on the op1f, but it sounds great. i used a telecaster on the first track “Meltdown” on my album here:
literally a cable from guitar directly into op1f, with a bit of the Phone effect and i think the Nitro too IIRC
Very cool! Enjoyed listening to those pieces too.
thanks you!! glad you liked them! the op1f is so much fun to use. even just messing around without an agenda is fun
I have been using the OP-XY more lately, but will get back to the OP-1f too.
