Using D4 
How do I get chord diagrams to play back? I have selected the speaker icon in the ‘Play’ page but its still silent…theres no MIDI signal in Halion either…
Select the chords track in Play mode, open the Routing section of the track inspector on the left-hand side and manually assign the track to whatever sound you want to hear.
Thanks Daniel, I had the vst rack tab selected, opened the Inspector and there it all is.
Thanks…Dorico 4 is looking really good by the way… Loving the Key editor.
Isn’t there a little speaker icon you need to click on to make it play the sounds you just selected?
Yes, Andy said in his original post that he had already switched that on, Marc.
