Beautiful FM

I’ve never reviewed an app before, but I am so pleased by this app’s responsiveness and sound that I actually went in to the App Store to write this. I have a Volca FM that I know very well and this app was easy to understand with that knowledge. I’ve played with a dozen (free) synth apps and this is the first that actually impressed me.

Super appli,

Je me demande juste pourquoi le modèle Mark1 sonne-t-il nettement moins brillant qu’avant ?
Aussi, ce serait bien qu’on puisse utiliser ses sons importés/personnalisés sur GarageBand…
