I was hoping to try out. Linda C. ### 2/5 — No sound *2019-01-27, version 1.1* It’s good but no sound in my iPad Pro ### 2/5 — Good start, but... *2016-03-10, version 1.0.2* Somewhat artificial sounding samples and quite slow to respond compared to other diatonic accordion apps I've tried. Lots of options and configurability, way more than other accordion apps, but fundamentally a musical instrument app needs to be responsive and sound good. This could be much, much better. Looking forward to future updates that improve both. I hope you will consider adding Audiobus and Inter-App Audio support, particularly considering the price of the full in-app purchase version. ### 3/5 — Good alp *2025-09-28, version 4.0.2* Really fun and helpful ### 3/5 — Wonderful app! *2025-03-15, version 2.6.2* Easy to use! ## Most praised reviews (10 highest-rated) ### 5/5 — Love it *2026-08-13* I like playing this is better than mezquite in my opinion **Developer response:** Hello accordionist Adiel 👋🪗, wonderful to know Accordion Diatonic was to your liking!
