one change between logic 6 & 7 is that when you send a stereo track into a bus it no longer allows you the option send to 'bus 1 & 2', only 'bus 1' (4instance)
this means you cannot (say) send a stereo track into bus 1 & 2 to have it then on two faders (for repositioning or switiching L to R, etc.)

any ideas around this? cheers jerry

Not sure what you mean, but surely you can assign a stereo track into a stereo bus in Logic Pro 7.
