Hi Harry,

It is possible to use an expression pedal and an AUX footswitch at the same time with the H9.

This isn't well documented but it works.

You need a 'stereo – Y cable' where the TRS goes from the EXP in on the H9  to a TS and an RS connector. Connect the TS to the EXP PDL and the RS to the momentary Footswitch. The footswitch can activate the TUNER. You just need to go into the SYSTEM mode or use H9 control to set this up. ie. UTILS>EXPTIP>BOTH and AUXSW>TUN.RNG.

We will make a video demo in the next week or so to make users aware of this feature.

hope this helps.
