Nice idea. Few small things.
Overall, great idea, nice concept. Straight on to the things that can be improved upon ^_^. While it may be there, I failed to find any way to record anything you made, not a big thing, but it could have been nice. The single hit pads i think could use short-cut keys so that you don't have to click them, but rather they be assigned a keyboard key so you can use them faster. To that end, while you could press one single hit over and over for an effect, youd have to wait for the light to die out before you could use another one, makes it hard to link anything together for sounds. Also, dunno if anyone else has had the problem, but the pan knob on the far left got stuck and wouldn't move from its position, all the others worked fine. By the way, like the detail you put into this. So, sorry reviews so long, nice work, maybe make a few minor tweaks, and good luck with anything else you ever create.
