Very nice!

I dig it, like the newest update as well. The onboard fx are solid, easy to use ui.

One request: anyway to take a look at the settings for allowing Apple Pencil to be used in app? It seems like it’s registering the pencil but not actually completing the function if that makes any sense?

This is something that comes up quite a bit in apps when they first roll out and then eventually it seems like it’s tweaked and fixed so I’m sticking with five stars on this one thinking it will be addressed at some point!

Hi Codowlsky, thank you for your review! Glad you enjoy the new update.

Regarding Apple pencil, Shaper does have stylus support. Once the pencil is connected to the device, it should work in Shaper without any additional setup. If you need help feel free to contact us at ,


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

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.
