OP1 field and M8 are great friends except midi out over usb doesn't work

I’ve been playing with OP1F connected to Dirtywave m8 over USBC and it’s just magnificent. Audio comes in perfectly, midi send from M8 is great, sync is great, you can print audio from M8 to tape with a single cable then jam over it and I am actually in heaven.

The only small problem is that the OP1F doesn’t seem to be able to send midi to the M8, only receive from it.

That’s well known and discussed on the M8 discord (where the dev is incredibly responsive) and apparently it’s something odd about the OP1F and how it handles midi in USB host (I believe this because I’ve always found M8 to work great with everything, and tho I love the OP1F I’ve often found it to be picky and odd…).

So I’m just posting this here (1) in case someone else hits the same problem (you are not alone…) and (2) in the hope that TE engineers are watching and would like to fix it, because apart from that these two devices are a match made in heaven, tiny, glorious complementary workflow, and I’d love to be able to drive the M8 synths with the OP1F keyboard and sequencers!

Any update on this?

The latest OP-1 Field update fixes a lot of issues, and now both can send Midi/Audio to each other. Works quite nicely :smiley:

I have the og op1, what was wrong with the usb to midi?

@floris89 Can you elaborate on your M8 and OP-1 settings. I can’t get any response trying to trigger my OP-1 from M8 via USB. Not sure what I’m missing.

You probably want to set your OP-1 Field (this doesn’t work directly with the OG-1) to midi channel 9, this will allow you to send Midi from the OP-1 Field to the current track on the M8. When I want to sequence the OP-1 Field, I’ll generally set it to the midi channel associated with the track I am working on within the M8, just to keep my sanity of what/where I am sending midi notes to.

Hope that helps…

Thanks. Problem I’m having is getting the OP-1f to remain connected to the M8. When I connect them I can see the M8 as Connected in the Op-1 midi device list, but then after a couple seconds it disconnects. What cables are you using to bridge them?

Just using a regular USB-C to USB-C cable… I don’t think it is anything fancy… used both the TE provided cable and apple cable and both seem to work fine for me.

Any special tricks to doing this? I can get audio from the M8 into the OP-1F, but not from the OP-1F into the M8. Not sure what I’m doing wrong.

EDIT: turns out my OP-1 somehow wasn’t on the latest firmware. Just updated and now all works as expected: full 2-way audio and MIDI between M8 and OP-1.
