Note silent in write mode but sounds in play mode

I’m getting a problem where a single note does not sound in write mode, but if I play the same passage in play mode, it does sound.

Is this a known problem? if not, I’m happy to post a cut down project showing the problem.

using NP4.5, NPPE, BBCSO Core, MacOS 14.1,

Dorico Pro Version (May 26 2024)
Dorico 5 AudioEngine Version

Many thanks,


It’s not known to me at least. Definitely upload a project. Is it just that one?

Perhaps you changed a preference?

Thanks guys, and I’ll look at that preference.

To correct my earlier post, this is a voice part and so it’s using NPPE and EW Hollywood Choirs. It might be relevant that NPPE uses a single EW patch for both soprano and alto.

Daniel, I’ve spotted 2 places so far where this happens, both with the alto part.

As you solve this, I’d be interested knowing how sending Hollywood Choirs (and WordBuilder) through NPPE works. I have always run Opus separately from NP.

I also wonder how clear the words are you find with WordBuilder; my effort often sound somewhat distant, slightly behind the beat, and mumbly in spite of different microphone settings.

Hi Derrek, I’m not using Wordbuilder, and I don’t think there’s any way to do that with NPPE in the mix.

In NPPE, a default instance of each patch is loaded and it can’t be edited.

I’ve listened to the Wordbuilder demos and at the moment I don’t think it’s good enough.

I’m hoping over the next couple of years that vocal renders get enormously much better.

I’ve updated to NP 4.5.1 and the problem has gone. This might be due to stopping and re-starting NPPE, rather than the software update, but in any event, it’s fixed.
