NotePerformer: No sounds while playing but fine selecting

I’ve had this happen before and am not digging up the solution … I took a iPad project and am viewing it in Windows, which select NP. In Write mode selecting and entering notes play just fine, however when hitting the play button I get nothing. Looked at everything with the routing, playback template and so forth and it looks fine, and anyhow don’t understand how it works in one way but not another - any ideas?

Well I switched over to EW Choirs and now it works, must be some Note Performer problem and yeah I think I’ve seen that before. I appreciate how NP tries to be the no brainer it just works VST but I find it harder to work with - and it can get into these wedged situations - more than any other.
