Amazing!

This is just extraordinary. I found it really hard to stop playing with it. Watch Hainbach’s YT video to get started then just have fun.

WOW

Hammer

Almost perfect

It would be great if there was an option to adjust the Layer field on the left and right for each of the three grains. Unfortunately, the Layer field setting can only be adjusted for all three together.

This thing mangles your sound, and I’m here for it!

One use for this app is to take original compositions and put a unique twist on them. Another is to use your voice (or someone else’s) and warp it into who-knows-what? It is possible to record sounds directly into the app, although I tend to prefer using existing sound files.

This thing is a bloomin’ playground! Great for soundscapes, which I’m only now later in life starting to experiment with. I am nowhere near fluent with granular synths, so reading others’ comments regarding improvements and alterations is interesting to me — stuff I never thought of.

But I’m going with a win-win on this one — and you can’t go wrong with the price point, either!
