I\'m not sure to answer correctly the question, Giga-mixer is suck! Normally I\'ve done the mixed-output-levels (giga) in the sequencer-mixer like cakewalk. Of course, when you have many tracks, it would be easier to control its mixed from an external-MIDI-controller faders. The advantage for this way is you can store (saved along with Seq.) and recall your mixed at realtime dynamically durring the mixdown processing. Anyone?
Hope this helps,
May be that\'s what GS presupposes. On the other hand, I\'ve discovered that using the directions keys instead of the mouse allows ten gradations within each colour band. So, as long as you\'re prepared to count the number of keystrokes, you can fine tune.
