No sound

Do not buy!

There is a newer version of this synth available. As of 22 MAR 2026 the product description of this synth does not state that fact. I was denied a refund twice by Apple in spite of this. Additionally, the developer would not help with a promo code to get the later version, which THEY ARE able to do at no cost to themselves. Due to this I will not buy nor recommend any of this developers products on any platform in the future.

Bellissimo, ma ultimamente….

Ultimamente, da quando ho IOS 18.6 , se non viene usato per 3/4 giorni il software si disinstalla e devo rifare l’operazione. Fortunatamente usandolo su Camelot il programma mi riprende al volo suoni e patch come se nulla fosse successo.
Magari problemi di compatibilità con i nuovi IOS?
