Hi – I searched and found this post. Describes what I’m experiencing too. I have 2 expression pedals and both had always worked great. Now neither seems to be working in the ways I recall.
In particular, I had a setting for the octave down in Black Keys’ Lonely Boy that had always worked.
a) I seem to recall having set that myself but I could be wrong
b) Yesterday, I could only get the flex to happen by hitting “flex” on H9 control – the expression pedal did nothing. Obviously, using a hand to flex dusing hte guitar part isn’t really practical.
Any ideas what might be going on? Also – is there a “flex” footswitch functon on the H9 itself?
