Thank you @dspreadbury and @MarcLarcher for the welcome and responding.
Telling Dorico what the drum map is to be in advance will not be a bad thing as I would have mapped the drums already. I tend to use the Groove Agent drum packs from Simon Phillips for jazz and Marco Minnemann for funk and fusion. As you may know, there are a lot of great drums to choose from.
Being a Cubase user, my focus has been on recording and using the software instruments to compliment or used as the audio. So, I got used to exporting data into a competitive product for scoring and engraving. MIDI is too exact and I have to find the time to make notation display changes. With me, simplifying workflow is so important.
In saying that, I love the new Dorico oriented features in the Cubase Score Editor, particularly the Note Editing Overlay. This really does make the difference between MIDI performance versus what musicians see when printing music. This is the reason for me using MusicXML for importing the data.
I look very much to tighter integration with Cubase and understand this will take time.
If you have any more tips, please let me know. Hopefully the forum can also contribute and I can in the future assist.
