I know it is possible to mix an audio track on the fly using a key combination which adds keyframes
But I can't remember how to do it?!

Open the audio mixer. Turn on Record keyframes Cmd-Opt-K I think, button in the upper right corner of the mixer.

Xavier...Press COMMAND-[ to go up 3db, and COMMAND-] to go up 3db. COMMAND - (minus) goes down 1db, and COMMAND + goes up 1db.

I use this all the time.

I prefer OPTION-APPLE-L, then a positive number to increase levels, negative number to decrease. APPLE-[] is too imprecise for me because it's hard to see whether it's taken effect or not. Also, OPTION-APPLE-L allows you to add/subtract any number you please, to any number of clips at once.

Neither Shane's nor my answer addresses your issue directly -- Tom's does -- but they're useful commands to have in your pocket. I haven't used any significant number of audio keyframes for a long time, because they're just too much trouble to deal with. (Overhaul time)

Or you can get that mixer you saw on my desk, the TASCAM FW1082. Those sliders interact with FCP and you can adjust on the fly. Either keyframing or adjusting the global volume of the clip.

The 1082 gives you four channels of balanced mic-level input, two channels of line-level balanced output and a control surface all on a Firewire interface, for super-cheap. We've got 'em in both online suites at work. It's neither the best audio interface nor the best control surface, but it's the best both-in-one available for the price. I highly recommend it.

(It is kinda big, though.)

I use the 1082 with FCP STP & Motion. Make sure you install the Cubase LE software to be able to control the
pan pots on all tracks from the control surface. Use the Cubase drivers, not the sugessted Mackie drivers.

That's COMMAND-SHIFT-K, Tom-- very close ;-)

But those Control-[ / ] or Control - /+ keys-- do they record gain points on the fly? I always thought you needed to slide them puppies up and down with the mouse or get a contorl surface like that neat TASCAM unit...

Sorry for taking so long to answer!
I already use Ctrl-[ to increase 3Db. But I wasn't aware of Cmd -.
Thanks!
