In all fairness: I asked PG probably already way back and just after in Atari days, when BIAB was still MIDI only, if they could incorporate a slave MidiClock, MTC or SMPTE mode for BIAB.
Never understood why they did not do just that.

I still think this VST makes the whole slaving thing far too complicated. Quite a thing to get used to BIAB and it's quirky interface and all those 'hidden' submenu-ed and sometimes quite useful functions. But you learn to live with that.

I've been trying to get things done with this VST, but still couldn't find an easy going & practical way of working with it.
A simple tempo or bar-count or key change, and off you go rendering the lot a gain, and so much slower compared to BIAB it seems. Call it the VST blues? This VST still feels like it's unfinished business. Sorry PG.
