12 years ago is “modern” by my standards 
that would make it the third most modern piece of gear in my rig after my BB and my looper
CC changes in the .sng file itself seems advantageous to MIDI Maestro control for several reasons, not least of which is I’m poor and was only just able to afford the BeatBuddy itself today, after pinching my pennies and dreaming about it for a few months but also ease of implementation and the convenience of having it controlled by the transitions you were already triggering (or maybe there’s a way to still do it with one button press with the Maestro i’m not entirely sure) there’s something to be said for the KISS / “Keep It Simple, Stupid” principle, and seems to me that CC changes in the .sng file itself are just about the simplest way to do it… no extra parts needed and it’s all done with elements that were already there / being used anyway, no second device to purchase, no patches to write, etc
(for real tho, (and yes i know you’re not an official dev ) I’ve spent the last couple weeks digging through the forums while I waited for my BB to get here, and it seems like lately a lot of feature requests are being met with “the MIDI Maestro can/will do that” whereas if it was a post from '15-'18/19 or so the idea would have been at least considered for the BB… And maybe it would be better for an introduction post that I should probably make, but even tho I jest about being poor it is the truth, I’m only 33 and have been fighting cancer for the last 5 years, and my “5 year survival” odds are ~17% so who knows if I’ll even live long enough to purchase a MIDI Maestro and see those features patched into it… =/ I digress sorry)
edit – i’m known for rambling and editing a lot as well, hi, I’m pharmakos
