I did a  PDF compilation of the graphs in a 2-up arrangement suitable for printing.  Unfortunately, it's too big to upload as an attachment.  If anyone wants to host it, let me know where to upload?

Thanks for all the good work.  It's a very odd marketing decision for Line-6 not to a) label effects parameters in terms of frequency and b)not make a family of graphs part of the technical documentation.  I don't think they're giving their customer base enough credit.  There may be a few folks who don't care about the details, but many of us do.

Wireless VDI would only be of interest to POD users, but it could be integrated in a more extensive bidirectional wireless system. Instead of having a heap of boxes and batteries on my back I'd love to have one system that combine guitar, mic (headset) and IEM. It may be relatively cheaper to add VDI to a design that already implements a shared bidirectional digital link.

Hmm.  I forgot that newer hi-tech wireless rigs work in both directions for audio.  I wonder what kind of data rate and signaling is used to control a Variax?  If the bit rate is slow enough (and you knew the protocol in detail - not likely without a non-disclosure agreement) you could translate it to frequency-shift encoding like modems of yore.   Wonder if Line-6 engineering ever pondered that approach?

With enough patience the on-wire protocol could be reverse-engineered.  More work than I have time for...

But, even at that the audio path from guitar --> POD would be analog.  You'd need something like fast wi-fi for VDI digital out. 

Wireless VDI would be a bit more challenging than sending analog audio.  Not the least of the issue is the need to have a return data path for control of the guitar.  My sense is that a VDI-capable wireless system would be quite expensive and have a very limited base of potential customers.
