Yes, that was the star feature. It felt more "organic," more like
traditional plugging-things-together-with-cables than Cubase on the ST
(another classic nevertheless)

Don't worry, I'm not going to suggest embedding B&P as a virtual
machine inside RG :-) The things I had particularly in mind were
1) Hybrid staff (a combination of piano-roll and notation staff - with
some chaps looking at refactoring the staff view, this might be worth
mentioning)
2) The various note manipulation tools, and if there are things there
that are useful but not yet in RG.
3) Any sundry usability tips/tricks that pop out at me (use of numeric
keypad for jumping to markers?)

One thing that occurred to me as a result of seeing the "pipe tools"
in B&P, but that isn't a B&P feature, was the idea of scriptable note
manipulation. e.g.embedding Small or some similar highly sandboxed
scripting engine, and having a simple API. For example, the script is
called with a struct for each note in the segment (or midi track?),
and it returns a list of note structs, with the restriction that it
can't insert notes "in the past." The MIDI equivalent of a LADSPA
plugin!

(Ok, that's my next project after the guitar fingering sorted... ;)
