Can you confirm that?! I'm still not 100% happy with the tone controls anyway; although the functions that change the tone set 0dB before setting 'Off' and reapplying the old eq bands, thus stopping the pops when adjusting the eq around the zero point, when the selected eq is changed, any current tone control is just applied. Maybe I need to mute this event.

I thought that the selected eq was the same for all inputs, and that there weren't input-specific eqs. With this in mind, an input change should result in the same eq as previous...and I can't see how a transient could really occur due to this.
