I use a podhd500 as an extra midi switcher for Axefx. The pod has some nice midi features - in particular the ability for switches to send different midi commands depending on the current pod patch setting, and, the ability to toggle pod switches on/off remotely. With the PosHd paired with Fractal Mfc and some programs I created in Bome Midi Translator pro software, I've been able to create a footswitching system for Axefx3 that's quite powerful (includes 2 additional sets of linked switches (8 in total) on the pod, initial state recall on the pod by Axe patch, a 2nd layer
of switches on the pod for looper functions, 17 switch functions on mfc includong 2 sets of linked switches + 4 linked scene change switches - 8 expression pedals (4 from mfc, 2 direct to Axefx, 2 with podhd).
Addionally, using the bome scripting I can swap in/out external post fx like Eventide H9 and Source Audio Nemesis delay to a specific mfc switch (ie - swap out Axefx delay, swap in Nemesis delay on the same
Mfc switch).
Currently I'm working on a seitch function that swaps in a plugin amp section - cool! - uses Axefx3 usb routing (kind of useless though as there are no amp model plugins I've heard that are better than axefx models).
The whole pod/mfc/bome thing is tiding me over nicely till I pull trigger on FC. It's not a mobile config especially with Midi translator needing to be running on a mac, but, the midi processes could be externalized with something called "bomebox" which would enable it all to run without a computer.
