So one of the first things I bought when I got a Switch was Korg Gadget.... ...and I hated it. I fiddled around with it a few times but literally everything it did was done better by Caustic which is free and that's because Korg Gadget on the Switch doesn't have MIDI controller support. But then they did an update so it supported playing the instruments live via a QWERTY usb keyboard and even though it's not the ideal method of control for live playing it works good enough that it's now a very nice piece of software and I actually love it more than Caustic now.
So this way my first experiment with playing Gadget live.
