I keep coming back to this app. If you like making funny noises and / or want a cheap source of custom spacey sound fx, this is right up your alley.

Make crazy noise. Scare the neighbors ' kids

I only give five actual stars to apps that are completely ridiculously over-the-top cool… This app is outstanding excellent superb awesome

Amazing little synth for the price. It's positively bursting with sci fi sounds and sonic possibility. The only thing holding back a five star review is the fact that the low frequencies are represented with the color black--on a black background! You can hardly see what you're drawing / manipulating down there. A more neutral background color could easily fox this. It would be really nice to be able to save patches too.

This thing is really FUN to mess with !!! Be sure to click on the little wrench to right, to try things like turning echo (reverb?) on or off. You can easily hear how different one set of frequencies at arbitrary amplitudes sounds distinct from the sounds produced by another set. Experiment -- your brain will like it and you'll a lot just intuitively...
