Also consider that during mixing a guy might just get all the balances ri=
ght,=20
and then link all the gain controls together to create the master control=
=2E =20
If you need to tweak one, unlink it, adjust it, and link the rest.  Can t=
he=20
gain controls be linked automatically separate from other track linking r=
ight=20
now?

Also, on some analog recorders (especially the old ones) there's actually=
 a=20
mechanical linkage on the volume controls.  Usually this is there to keep=
 L/R=20
in sync, but I've seen them where you adjust the volumes and then throw t=
he=20
mechanical linkage on to move them all at once.

Um, also, I don't know how the Amplify effect works right now, but we may=
=20
still need to be able to amplify a sample beyond its sampled volume.  Man=
y=20
samples taken low for fidelity's sake need to be amplified later and will=
=20
have plenty of room over 140% or more (like my microphone) for more=20
amplitude.  Either that or I don't know jack about recording, which is a=20
serious possibility.  :)  Also, after appying certain types of effects=20
(reverb and phaser come to mind) a sample will actually drop in volume, a=
t=20
least compared to the rest of the music, and will need to be amplified ag=
ain,=20
and may easily go over 100% (or even 200% if the effects are strong enoug=
h).
