I have Cantabile 3 Solo.
I haven’t been a serious user in the past but due to DAW issues I may become one.
I have seen references to (and screenshots of) a Midi clock section in the options dialog but it does not appear in my copy of Cantabile. This is needed because I’ll need to able to sync the tempo to an external source.
I also have Finale, Notion, and Cakewalk. For the past few years I’ve been doing everything in Cakewalk but I can see good reasons to split the midi sequencing and VST hosting. I am trying it out now and fortunately the piece I’m working on has no tempo changes.
