Hello, I’m new to Dorico (switched from Finale). I’m a Mac user and sing with a quartet. I used the SATB template for an arrangement, which has a default of choir aahs. These are too fluffy for learning purposes so I like to change them to trumpet sounds, then I alter the volume for ‘part dominant’ audio files to share with the rest of the quartet. I found a sound I liked (real brass in Halion Sonic). It played back fine in Play mode but when I exported it to MP3 it had reverted to choir aahs. I checked the channels and renamed the files as suggested in other threads on here, but this hasn’t worked. Please would someone tell me where I’m going wrong?
Hi @babswilson, and welcome to the Forum.
Edit: see the posts below for solutions 
Here my previous suggestion (possibly helpful for other situations)
I cannot reproduce your issue. After manually assigning the Real Brass patch to the four channels in Halion Sonic, the exported audio (mp3) sounds as expected:
manually changed patch.dorico (1.5 MB)
Exported audio:
It should work. Can you share more details on how you load the new patches, and how you export the audio?
You can also try to save the Endpoint Configuration, then create a new Playback Template, and load manually that EC into it. You can then apply that PT, before exporting the audio:

Is this another case of the Mac media player cache-ing audio files? (There are recent threads on this)
Try changing the file name and re-exporting the audio.

Right, here is such thread.
Better still: don’t use the Music.app (née iTunes) to play MP3s that you’re revising.
Hi Christian, thank you for your thoughtful and helpful response. I love the tip about creating an end point template, I have done this and it will save me lots of time in the future. Thanks again.

Hi Janus, Benwiggy and Ulf. Yes I think that the cache-ing issue was the problem. I had read the previous threads and renamed the project, but what I didn’t realise was that I should have been renaming each MP3 within Apple Music. Otherwise it saves as ‘untitled project’ every time and then plays that back again instead of the next MP3. Unless I’m missing something (always possible) you can’t name your audio files when exporting them, because this would be ‘problem solved’. Also good point Benwiggy, it played fine in QuickTime Player but unfortunately I’m quite wedded to Apple Music. Thank you all for your suggestions and I’m glad to have a work-round. I hope the clever people at Dorico will give us the ability to name MP3 files soon. On the whole I much prefer Dorico to Finale but this feels like a backward step.
