Well done on releasing 4.0.30. Amazing and brilliant hard work, and most appreciated.
I guess the Play Mode section of the manual will be along to the party a bit later in the evening, or have I missed something? In the meantime we can continue to refer to the 3.5 manual for this, is that correct?
The Dorico 4 Operation Manual does not yet contain any information about the new Play mode. For the time being, you should refer to the Dorico 4 Version History PDF for information about Play mode.
