A modified 4 player cable works, made one myself for MIDI syncing more than one nanoloop.
Just solder all the IN lines together ;)

Well, I updated my OP-1 to the 2016 Beta OS to check out the PO sync and it works (if you double the tempo output)!

And actually building a half clock to full clock converter wouldn't be too bad.

But I think the best way is to just build one of these and include the USB Host shield: http://gieskes.nl/master-clock-generator/
Avoids drift and it's a cool project. I'll probably build one in the next couple weeks.

I really don't understand the point of it.. if you have to essentially implement a tap tempo feature in order to actually process a sync pulse, isn't that inconvenient/inefficient?

I'm actually kinda tempted to just get rid of the op-1 and maybe get something with real MIDI in/out like the Novation Circuit. As good as the op-1 is for lazy couch sound design sessions, it's really not very convenient to use with other devices, without a laptop in between..

It won't be so hard for arduino to double the PO sync signal to match nanoloop's analog slave sync. Definitely much easier then dealing with usb-midi timecode...

edit: but I agree about the half sync.. wish there was an update for my volca to get pulse per step sync

It's a conspiracy!

Nope, nanoloop only supports half-speed sync as master (according to the manual anyway, I haven't tried nanoloop as slave!).
If only the OP-1 supported sync *input*.. it's got the mic input, I don't see how it couldn't be implemented!

Urgh, whyyyyyyyyyy :(

Apparently, the new beta OP-1 OS supports pocket operator sync via the headphone out (sync pulse goes to tip of plug). Unfortunately though, it's that silly half-step sync scheme (seriously why did anyone ever think this was a good idea)..

No, that's really great! That means the OP-1 could be master for nanoloop as it supports analog sync and works with the POs!! This is great news - looking forward to that release. Woo!

So, I did it... almost.

Code here: https://github.com/2xAA/MIDI-Clock-Convert

There is a pretty significant drift on any BPM over 120 though, I'm not sure if that's nanoloop's fault or the OP-1's. Could be my code but there's not an awful lot going on to slow any transmission of the clock.

I'm probably gonna put my money on it being nanoloop 2 as it doesn't have the best clock in the world. (I've had to USB-MIDI sync my recordings from it before just so when editing I don't have a huge drift to deal with)

Anyway, that's it pretty much.
I had to use an Arduino MEGA in the end as for some reason using the default Serial and the USB Host shield is a no-go, so I used Serial2 on the MEGA instead.

Thanks to catskull for advice and encouragement :)

ah yeah cool, I didn't even really think of using the pi as a host but that might be a good idea.

My current project is to make a replica of the nanoloop sequencer (and synthesis engine, to a certain extent) in pd.. so really I probably won't have to sync nanoloop to anything.. especially since I'm becoming better at using nanoloop 2 by itself or synced with another copy.

I've had success with using a raspi as a midi host syncing my DMGs and my electribe, and it's not hard to set up so that it automatically sets up the connections on bootup

Hey Sam, message me. I'd love to help get this off the ground!
