Very powerful app for granular synthesis and sound design. The midi control over loop playback position turns it into an experimental sampler. I would pay again for a VST version.

Awesome. This app is deep and complex. But you can get some amazing sounds with samples. Only issue is I upgraded to full on my tablet but the full version is not showing on my phone. Landscape view would be great too.

3.5 stars if it didn't start running every day for no reason using 30% of my entire days' battery capacity. Without the battery issue it's ok, unfinished and unpolished, but it does do a lot

Really nice looking piece of useless garbage?.. Cant get this app able to do anything useful except make sounds/music sound stupid, just a messy kids toy!, buggy as F rarely loads up without everything jumbled up and not scaled to work, Haven't these devs ever thought that users could do with some built in interactive help a tutorials?, this program does absolutely nowt!!! Time wasters.....

Loopspins when recorded cause the disk drive to eject.

Fully broken on my S25 Ultra. Freezes if I try to add any track beyond 1. Seems like it may still be the mic issue that was thought solved with the new update.
