Reversed latching in Ext Amp function

[pablo5150cz]

Hello,

Enjoying my new HX effects I really appreciated a possiblity to assign two switches on HX Effects to Channel and FX Loop switch of my amp (and get rid of original footswitch).  Assignment went OK, but unfortunatelly the switches are displaying Channel status and FX Loop status in oposite way (f.e. when I switch from Clean to Drive Led goes from On to Dim). I use TRS to TRS  cable, the same jack which is on the original footswitch. And yeah, I use Marshall DSL 20HR head. Any idea? Thanks!

I overcame this on the floor by setting a gain block to 0dB and assigning it to the same footswitch. 

You can then toggle the state of the switch by setting the bypass on the gain block.

 

Admittedly you probably wouldn't want to burn two blocks on the HX Effects just for that.

Just a suggestion. Maybe it's not actually a problem. On my Mesa Boogie .50 Caliber Plus, the LED on the included footswitch is ON for the Rhythm (clean) channel, and OFF for the Lead (dirty) channel. So maybe it's not that something isn't working properly, it's just that you have to get used to what the LED state mean. Just my two cents.

Assuming you already tried different combinations of the values on the 'Select' parameter on the Ext Amp settings in Command Center. Maybe rewiring the TRS cable might do the trick. Believe I have seen some solutions posted along those lines before on the forum.

 

Also, doubt if this will be of any help to you but found the note below on Helixhelp.com. The only way I can see this as being helpful is if it makes a difference whether you save the preset with the footswitch with the LED ring either on or off.

 

NOTE

When an Ext Amp command is assigned to Instant 1-6, the connection determined by Knob 2 (Select) is made when the preset is loaded. When an Ext Amp command is assigned to a footswitch, the footswitch's current state (dim or lit) determines whether or not the External Amp connection is made when the preset is loaded; when dim, no connection is made; when lit, the connection determined by Knob 2 (Select) is made. Subsequent presses of the footswitch toggle the connection on (LED lit) and off (LED dark).

Thanks for the inputs! I didnt have time to try out all the suggestions, but assigning a gain block at 0dB works. But: when I assign a gain block to FS4 which I used for channel switch, it works. Then, I tried to assign another gain block to FS5 which I used for FX loop switch. It didnt work. First problem was that this gain block created for FS5 was on the right from FX loop icon (I was in 4CM mode). There was some terrible noise issue during latching on/off. So I moved this gain block to "preamp" mode. The noise was away, but I wasnt able to set it in a way I wanted. Will keep trying. I need to move my amp from rehersal room to my house so I can have more time to investigate.
