Sounds like battery powered hell, I think VCV rack would be better! ;-)
Though I guess a Bluetooth Rack-Plumber would be a good idea if the price poit could be as with a Plumb Audio Rack Plumber.
Enjoy your spare HP, don't rush to fill every last space, this is not like filling sticker books. Resist the urge to 'complete' your rack, its never complete so just relax.
