There are 8 tap points on the board for track outs - in good time you’ ll maybe have an option to have a breakout box - even i’m tempted too, but i’ll do my own version for the fun when all the dust has settled on issues with that. So, at least it looks promising that some of that wish can come true. Turn your attention to Elektron and see if they’ll support that mod by allowing the software for the outs (if any) to be included in the A4 !
what’s in the red box ?
