Anyone using H9 with an Expressionator (and an expression pedal) plus a separate aux pedal? I gather I’d need a stereo/mono splitter (e.g., I believe EBS ICY-30 would work) and wire as follows: connect stereo plug to H9 aux out, connect “ring” mono plug to aux switch, and connect “tip” mono plug to something like the Mission Engineering Line 6 adapter, to convert from mono to TRS, and plug the other end of the Line 6 adapter into one of the Expressionator’s TRS outputs. Just curious if anyone has had success with this.
