Its not possible to directly control any of those amps like that with the POD and vice/versa. You'll have to control both separately unfortunately. Line6 may have an amp that could do this easily via FBV port. There are some instances where you can achieve this with certain combinations of amps/MFX/Switches, but more often than not, this would require a modification of some kind to keep the switching lines compatible with the device your trying to control. Boss seem to be the most thoughtful with this. They have switching pedals that can interface with alotta different amps and MFX pedals and even synths.
EG: The Boss FS-6. And the FS-5L. I doubt any of those will control the POD via the EXP.2 socket. Pretty sure Line6 just made this socket exclusive to expression pedals only, where as other manufacturers have made this socket a dual purpose one that can have either an expression OR a switching pedal connected to it. But not both simultaneously.
Or use a MIDI interface for more dedicated patch programming using. Or my Carvin V3 head. Comments about TC Electronic G-Major 2 Guitar Multi-Effects Processor.
S7 200 Modbus Slave Library Download. Hope this helps. Or even cheaper: $96 you could use that to control your POD remotely as well as switching amp channels. And if you gig a lot in small pubs/clubs like I have in the past - I'd much prefer for a little beer to be spilled on that Behringer pedal than my POD.
Cheers Andy Im not understanding how that behringer could give you access to channel switchin on those amps. If the behringer connects to the POD HD500 directly via midi, whats going to amp to switch channels? I see 2 TRS type sockets on the back of the behringer, are they switching outputs rather than inputs? Side note: owned a Blackstar HT 40. First amp I've regretted selling. Great tones top to bottom. My bass player owns it now and promised me first dibs if he ever sells it.
I still play through it now and then at our practice space and regret selling it every time. Contemplating a new amp; ATM looking over a Marshall DSL40c or Blackstar ht 40. Both have dual channels and come with foot switches. Will my hd 500 work as a channel switch or will the factory foot switch work in conjunction with the hd?
