Best piano App.

I bought it and wasn’t that impressed, UNTIL I played it on my NEW iPad. WOW! This thing is incredible.. maybe the set up on my old iPad was incorrect. Don’t know.. i’ve tried all the rest. This one is the best.. The Grand, the Upright, amazing. ❤️🎹

Best piano ap I’ve ever tried. It’s perfect.

It’s a virtual Clavinova. Outstanding with external midi controller. It can get expensive but its so worth it. Just get it. You’ll use it all the time.

Old interface but great sounds

I’ve been using this connected to my Roland digital piano for years, the sound quality is a thousand times better than my piano defaults. The only real negative is the outdated interface that’s hardly changed in the 5+ years I’ve been using it.

$75! No trial offered!

Why would anyone pay $75 when Korg Module Grand Piano is completely free

Poor interface design

I use the Music Studio app to work in music. The Crudebytes Piano app is seen as an Inter-App in muisc studio. Load the piano sound and the spund SOON DISAPPEARS and this makes the app UNUSEABLE, you cant depend on it. Also has no Release Control in Music Studio, you cant get the piano sound to continue being heard after you Release the piano keyboard keys. I paid too much for this overhyped up app
