I'm hoping someone else has figured his out. The manual for my GT10 says there is a way to set the heel down position of the expression pedal to the tuner. I've tried to follow the extremely vague instructions but so far have no luck. Can anyone help? Thanks.
I followed the instructions in the manual and managed to make it work on the second go I think.
Make sure you have the Display Mode set to the list view, so you can see the correct parameters. I can't remember exactly how I did it, but I made it a global setting so the tuner comes in when the pedal hits 1 on all the patches.
