It would take at the very least replacing the USB port to one that includes an audio interface for communication with Overbridge and new firmware. The audio interface would also need access to the signal chain, which would require more connections, both hardware, and in the firmware. It is probably even more complicated than this though, and I would doubt that Elektron would offer some kind of upgrade due to the likely complexity of the mod.
It would most likely be a warranty/support and financial nightmare for them and I just don’t see it happening.
Now an Octatrack V2 with Overbridge could happen at some point. I think it would be a great move for Elektron and would sell well.
