I don’t think it has anything to do with processing power as such. There are different USB chipsets for different purposes and the OT has one but not the other, so the only way to change this would be to swap out the main PCB. I forget which specific chips it is, there’s a post of mine in some other OT overbridge thread with more detail. I’m not sure why the OT was not built in a more modular fashion or to accommodate future hardware upgrades, but my guess is that Elektron thought they had solved that issue forever with the CF slot.
They’ve always presented the machines as standalone performance devices so it’s not that surprising. They changed the build philosophy in several respect with the Analog Four and from a commercial standpoint the new direction seems to have taken off very well for them. I would sort of like Overbridge in the OT but on the other hand the whole reason it’s at the center of my setup is because I can quickly build music ideas without the computer so I’ve gotten used to working with the 4 outputs.
I agree with the posters above that the chance of this happening is virtually zero and there’s no point in torturing yourself daydreaming about it. Maybe in an OT mk2 down the line.
