I have an A25 and a S series mk2 61 keys, how can I use the A25 in standalone, I have the Asio Driver installed on the computer. I also have a M-Audio interface. At the moment both keyboards can work together. I don't want to ruin the set up as it is, but I would like to use the A25 in standalone if one won't conflict. The A25 only has a usb connector but the M-Audio interface has midi in-out. Is any of this Feasable?
