I would love to see the development of mobile companion apps for the Mastermind PBC. I currently take my laptop with me as a part of my rig in case any setlist changes happen at a soundcheck. It sure would be nice to be able to leave the laptop at home. I have an android phone, but I also use an old iPad mini 2 occasionally. I expect it would be easier to implement an android editor than an iOS one. Android freely lets you use usb for what you want it seems. Apple locks their hardware down. Just some thoughts. Thanks for the great products, RJM! I really love my PBC/10!
