Good youāre asking! I have recently bought some parts for a solution⦠Itās ugly, but has been working great so farā¦
I got this usb switch:
Then I use two of these:
And a A-A cable which goes from the switchbox to teletype⦠Then the Keyboard to one āinputā and the grid to the other, each via these adapters. Donāt forget to power the grid of course!!! I have a (monome) switch in between the grid connection.
Again, not pretty, but have it vertically standing at the side of my case, the long adapters hidden behind, and I can switch focus/input with the press of a button. (of course grid interaction stops when the focus is on the keyboard)
One caveat I found: some cables A-B wouldnāt work for some reason. Also had to sometimes re-power via the monome switch to re-gain focus on the grid. Using another cable fixed the issues I had. Might have been broken or poor quality cables. But this is still only tested for a few hours.
