Perfect poly with great ui.

I think this is a bit underrated as it sounds so ace! Its amazing that it can be used on mac and ipad/iphone. Also the loop maker is basic yet amazing feature and well its just working and no crashes so cheers! Maybe add more color but its still a user friendly ui.

I’m blown away at how good the filter sounds on this. This is one of the best sounding synths on iOS, the analog realness of it incredible. The developer is a coding wizard, all of their apps have been on point with the sound and processing
