I can't find the 'Pedal Calibration' tab under the setup button as stated on page 50 of the VoiceLive 3 manual?
The current firmware (version1.0.00 build 55) doesn't include this tab. To get to this page press and hold the vocal button. This will bring up the 'Expression Pedal Calibration' page.
This has been corrected in the latest firmware release.
