Working It: TUNING UP
5•3
CHANGING THE TUNER REFERENCE FREQUENCY
What if you want to tune to a different reference than A=440Hz? When you’re using
the tuner, you can turn the
Mid knob on the AX2 while watching the ever-handy
display. You’ll be able to set the reference frequency anywhere from 335-445Hz
(440Hz being the standard reference for tuning). This setting is stored so you don’t
have to reset it every time you turn on the AX2 if you decide you want to be different
(or if that piano in your rehearsal room has decided to be different).
By the way, when the Tuner is used, the Aux channel will still work. So, for instance,
if you have a microphone plugged into the Aux input, you can still talk to your
audience while you’re tuning up.
NOTE THAT THE TUNER BUTTON WILL NOT SELECT TUNER MODE WHEN THE DELAY
EDIT ROW IS SELECTED.
The TUNER button does double duty to provide a super nifty “Tap Tempo” function.
With the Delay edit row selected, instead of tuning, tapping this button sets the
MAIN DELAY TIME to the tempo you tap. For the complete scoop, see the discussion
of the AX2’s Delay effects later in this User Guide.
SELECT TUNER WITH MIDI PROGRAM CHANGE
Want to be able to switch on the tuner by sending the AX2 a MIDI command? You
would most likely do this if you were using a MIDI foot controller with the AX2. Just
press and hold down the TUNER button, and turn the DELAY/REVERB knob to
select a MIDI Program Change number (from 1 to 128, or OFF) that you want to use
to kick in the Tuner.
