Not sure what the mK is going for these days, but I bet you could grab one and pair it with a cheap Yamaha XG sound module (like an MU unit) or something similar to add some of the cheesy sounds you were looking for. The fact that you can setup and store multiple profiles on it makes it quite versatile. You can use the faders for mixing the six tracks (mine worked for this purpose, straight away; fantastic for fading tracks out, as well as for builds), use the encoders for parameter changes, and use the joystick for modulation duties. I can almost guarantee you’ll wind up using it for more than just note input in a live setting!
