that’s exactly what monome switch does. it was designed to also power the grid from another source than eurorack power, in order to prevent noise caused by the LEDs. If you don’t have noise issues I believe you can also use switch without the additional power plug (untested). Unfortunately it’s deprecated, but they come up second hand from time to time.
Wait, after thinking about it, a simple usb switcher should work! no hp too.
I have one from china which I use for switching the TT keyboard between desktop and TT. super useful. [quote=“benniii, post:1, topic:8226”]
2) is there any fiddly hack that’d let me use my (other) monome 256 with both, simultaneosly?
Not possible sadly. Theoretically I guess one could build a 256 double kria firmware and send the second half of the outputs to a second ansible via i2c. But that would involve some hacking.
