I'm a newbie so I may have missed how to do this.

I would find it very helpful to be able to disable all bands with a single command. The same goes for enable.

Why you say?

Event sequence
a. add n bands
b. wiggle a couple clicks
c. stop
d. disable n bands
e. wiggle until score maxed
f. stop
g. enable n bands
h. goto b

often results in multiple positive gains.

User actions b thru g require 1 + 1 + n + 1 + 1 + n, or 2n + 4 operations. By having a enable/disable all bands the number of operation becomce 2 + 4 , of 6. A reduction of 2*(n-1) user actions.

In addition the act of enabling/disabling the band requires mouse positioning, click, mouse position, click and the band may be obscured.
