Thanks for creating this app I think it’s super dope 👍🏼👍🏼 Feature Request: 1. Can you make it remember piano key size 2. Make the pitch slider slightly wider it’s too thin 3. Arpeggiator would be nice 4: I also wish we had the option to hide the keyboard when using it as an audio unit

So happy with features of this synth! Literally after downloading a bunch of different kinds. Great for sound design. PerfectUI and just a pleasure to use.

Really good synth! Hey there is a problem with the touches getting delayed at the very bottom of the screen on iPhone, probably iPad too.

Developer Response ,

Thanks for your feedback! iOS reserves a small strip of the space on the bottom of the screen for opening its control centre. That said, we do have ways to fine tune this behaviour and we will have it addressed in the next update.
