Sorry. I missed the intent of your question which was focused on multi-part songs and not the one-press variety. Yeah, it is a pain to have to export each part of a song, do the edits in a DAW and then add each MIDI part back to the BBM song. I think this is why some users would rather edit the drum kits instead.
To expand upon your thoughts just a little further, I wonder if there’s great enough user demand for a BBM utility where a user can batch the entire process:
[LIST]
[]Export to MIDI files all parts of a song
[]Select the instruments to be edited across all of the exported MIDI parts
[]Edit the velocities for all the selected instruments
[]Add edited parts back to their respective locations in the BBM song
[/LIST]
It would even be better though if the BBM MIDI Editor were up to that task where a user had the option of selecting the drum instrument(s) across a range of parts within a song or a range of songs within a folder or a global change across all songs in all folders for say, toms, cymbals, etc and then editing velocities by percentage. Example reduce all crash cymbal velocities by 35%, increase all tambourine velocities and cowbell by 20%.
Wishful thinking, I know and for now, I’d settle for an updated BBM with bug and performance fixes as well as a few features such as autopilot. So far just crickets and vaporware :(.
