Unplayable on iPhone 12/Now Presets broke!

Update broke presets. Deleted/reloaded app. No change. Can no longer access presets on my iPhone 12. What lousy test. Really sad. //\\ And that’s the last straw. Universal app my tooshie. I have not bought an Apple app in months because of continued decay of quality and this is the last one. It won’t play in the background using it as a Universal App. Seriously? It won’t save state even upon exit. The developer zoomed in for the iPhone photos, that’s deceptive. The pamphlet is NOT a manual. This is pathetic and it’s taken as good quality. Well for the iPhone 12 it’s a joke and the end of Apple App purchases. It’s just a waste of money. Goodbye. Deleted app. Happy Trails.

Excellent App

Update: latest firmware addressed the issue below. Upgraded to five stars. Excellent dev and experience. Job well done!! Fantastic app outside of one issue. Every time you load the app, you have to turn down the LPF, otherwise there’s a slight audible noise. No other app to my knowledge does this.

Portable O-Coast Type Synth

Very fun synth/effect app that has a feel similar to Make Noise’s O-Coast hardware synth. It has a nice mix of Moog and Buchla character and with the sequencer or drone mode you can easily lose an hour just fiddling. Delay reverb effect is old school and gives the app even more of a hardware feel. It plays nice with other music apps also. Another hit for this consistent developer! Thanks!
