Notion 6 has some improvements in automatic tab creation which I like. I have not yet tried to do any drum programming in v6, but I'm hoping the, what look like noticeable, major improvements actually make drum programming a pleasure instead of a PITA.
I think it's time for me to finally get on the ReWire wagon and give it a go.
I've spent a lot (too much) money on notation software, looking for a workflow that suits me. Sigh.
