I imported an xml file into Dorico which I had previously converted from Finale .mus format with Finale notepad. It is a string quintet arrangement which needed a solo piano part adding to it so I created the piano part and entered it with my midi keyboard. I have been trying to go through the file to tidy up the string parts but the playback sounds like it is coming from inside a tunnel. This happens with any playback configuration that I choose and tuning off reverb has no effect at all. For a test I decided to export it as an xml file to Sibelius and it plays back fine with note performer. Nothing else works with Sibelius so I have only tried Note performer. This is the only xml import that I have had this issue with but it is also the only file I have converted from .mus format.
Any ideas. I’m stumped,
