Question: I want to connect a casio px410R piano to another keyboard & mix the sounds live for gigs but the Casio only has usb terminal, no midi ports; how do I get round this? Any help appreciated.
You can't send audio via a MIDI port; even if your Casio had MIDI, that wouldn't help you. Buy a small mixer (I use a 4-channel Behringer MX-400 that cost me about $40) that will take at least 2 inputs, and send the output from the mixer to your amp. Alternately, buy a better amp with more than one input.
