### 1/5 — Only the demo works???

*2023-09-25*

I wanted to like this but could not get it to play after making my selections. Only the 1st demo would play. I spent a few hours with it but it only said “composing” and never played on my ipad OS 17.0.1

**Developer response:** It should work - CalmusPlay has the same corre as the free version but the server has been busy because of heavy Web traffic. It is working fine now…
