THanks for all the info. I should have explained how I have it setup better.
So I have the HX,Tonex,Ampero Control,Mission Engineering EXP( got a great deal on it) and 2 Ampero Dual CTRL switches.
So the connections,
I have the EXP into HX using TRS cable for the EXP and Switch function. Set for Exp things and the toe switch is functioning
I use 4CM for Tonex into HX loop but also Midi OUT from HX to Tonex so that when I make a preset change on HX I cant also set FXLoop to change tone model on Tonex.
I have the Ampero MIDI out into HX MIDI In only at the moment to control Snapshots now and most likely other stuff with bank switching.
Then I have the 2 Ampero Dual CTRL's into the 2 EXP/CTRL jacks on the AMpero Midi. Set as Looper Functions. Already owned them so figured I'd use them.
So far all this works except for the 2 problems I mention.
One being I can not map any external MIDI device to trigger the HX Scroll Down switch. I can with all other HX switches but not that one(HX FS4 switch). I tried the Ampero,I also have a Nektar Pace MIDI and same. I even dug out the FCB1010 and same. The switch works on the HX fine.
Now for the scroll up/dn midi commands I tried cc49(FS1) and cc52(FS4), cc49 works but no matter what cc52 will not.
Two, The tonex Reverb Color getting triggered when using midi from Ampero. As of now Im not using any Tonex FX,just Tone Models. But who knows down the road plus I just got the HX so I dont even know at this point is something could be faulty.
So I did try changing Tonex CH. to 2 but then the HX presets change doesnt change Tonex Tone Models which I do want to keep.
I do understand the FS7 and FS8 being EXT devices, got that covered.
I give this a go later and see how it goes.
"If I read you correctly, you have a 2-button Momentary FS? Connect that to either the HXSXL or the Ampero with FS 7/8 configured to scroll <> the MODES, then use the Ampero Footswitches to emulate whichever HXSXL switches are required to do whatever. When I was testing all of this, I wound up just using Ampero FS1 to scroll the MODES one-way (HXSXL FS7 set to FS MODE>) and used Ampero FS2-4 to select the three options available in each MODE on my HXS. Since you'd need 4 switches for Snapshot Mode, using the 2-button switch for scrolling the MODES would work well for you and you could use the two switches to scroll the MODES bi-directionally."
Thanks again.
