I love it, I layer all of the tracks simultaneously so it sounds decent and use it as a one-track rave-hook machine. It's hilariously noisy if you try to use it for whole songs.

What are you finding tricky? It took me a little while to work out which button I had to press to go into the editor mode. The instruction booklet is here. The layout isn't a million miles away from your standard DAW, with individual loopable regions in a larger arrangement window, using a step sequencer, but I admit editing on it is cumbersome. Keep practising and you'll get there!

Anybody here ever used it?

I just got it today for £2, and it's probably the single most confusing piece of software I've ever come across...
