Nicely thought out design, a solid foundation upon which to build acid

Simply Stellar

I’m a Rebirth user from 25 years ago. Moved away from electronica, but have returned recently. I looked at many 303 apps on Mac, but none matched my memory of Rebirth (Phoscyon2 is pretty good though, but 10x the price of Pure Acid). Superb UI, great sounds, nice presets to jump start things. No annoying subscriptions, which I rarely acquiesce to. Great price. Just get it! Oh, and as always, Slava Ukraini! Since the war began, I’ve discovered that many of my favourite apps are written by Ukrainians. Hope to visit one day, once they kick the Orcs out.

Audio Cutoff

Hey my friend I love this app so much! Can you make it to where it doesn’t blowout/stop/cut off when trying to record on GarageBand when using Inter-App Audio especially and specifically when you’re getting into long recording sessions causing you to have to start your track all over constantly until it goes all the way through or if it’s loud. Ty my friend.
