I just want to add that this month's TNT is outstanding! Thanks Steve!
@fredwardo, It's an interesting idea... it might be easier to assign the sends to knobs/sliders (or even a foots pedal) on your MIDI Controller.
Off the top of my head, using the method in the TNT, Logic's Transport would need to be running in order to create any sort of "gradual" movement of the fader... in conjunction with some extra transformers and delay objects of course ;-)
What do you think?
