Hi all. I have a question regarding the QY300 sequencer. I just purchased one and can't find any information in the manual about hooking up various keyboards, so as to control them individually from the QY. There seems to be nothing in the manual regarding this. So how do I set it all up to record midi channels and play them back without having to listen to the QY's internal synth?

i have no idea what this piece of equipment does. Would anyone like to explain it to me? I've just been staring at it for a week trying to figure it out. A friend of mine found it in his attic and just gave it to me. Here's a picture...
