I’m guessing you’d have to do some massaging on the inside to sync the messages to the clock (I’m guessing the data would have to fit neatly inside two bar messages, and you’d have to increment the time clock data every loop, or the destination loop wouldn’t actually play the notes), but once you figured out the basics, it would be pretty simple to add some pretty neat features.

One that jumps out would be the ability to selectively mute/solo channels that were being looped, and maybe flip them around instruments – although that could get complicated design-wise with analog hardware.

I have the impression Limor has pretty well moved on from the x0xb0x and isn’t much interested in doing more with it. But I’ll learn about its feature set when I finish assembling mine; and of course you’re right about the open-source firmware.

Learn it, love it. In the context of this one single thing it may seem like an extremely large undertaking, but with a few days of poking around you’ll see that a lot of things you have ideas to do just get simple. Can’t recommend it enough.
