How big a market opportunity for 13 pin add-ons?

I have been reading this post in the interest of seeing what in the 13 pin world could serve as a replacement for my Line 6 Relay G90.
Also that mention of "Synth Snobbery" hit a nerve. Definitely been treated that way.

Anyhow, much of what you are looking at appears to be switching hardware and I did look at the jacks, plates, switchboxes and how big such a market could be.

Nobody mentions Kickstarter for funds so I guess the GK 13 pin world would never catch on?
Has anyone considered using the Raspberry Pi in a box for processing what's coming out of the hexaphonic pickup?

Sorry for the ignorance but where is the AD conversion done on these devices? Is it in the GR55, GR99 or other Roland box?
Does that mean all the "readings" leaving the instrument are analog along with the mag PU added as well?
What is the feasibility of the following:

- Convert all signals from the GK3 as well as the normal magnetic PU using AD conversion
- Using off the shelf Bluetooth (or possibly for extra range, wifi) to send the signal wirelessly to a receiving unit.
- The receiver could include some form of switch technology much like a typical Cisco device to handle other devices also in the chain. (possibly multiplayer?)
- The Raspberry Pi would be programmed to handle all the IO with possibly multiple outs for sends to say more than one 13 pin device. (Example output to a VG99 and a GP10 or GR55)
- Lastly, if you are sending the guitar's normal PU, then the DA is done there as well to send to your signal split.

Too complicated or expensive to build? Probably. Lotsa brainwork for the simple desire of having no wires again and the potential to run a rig which includes boxes outside the Roland synth world.
I don't have your knowledge or chops but enjoy the reading and rehearsing when I can.

Not sure how it could be worked out but looking at all the rigs out there, it would seem that wireless technologies are cheap enough and mature and with processing speeds of CPUs today, such a setup could likely be done without worrying about latency.

End state would be a guitar sending a signal to a receiver thus eliminating strain relief issues from jacks, plates, etc. and the receiver could have the potential of being a "music signal router" to your favorite mix of devices.

I saw the Fishman Triple Play system but my issue would be going on stage with any device that relies on a PC or Mac. I also prefer the maturity of Roland's technology. As a 25 year IT Admin I have seen all kinds of instrumentation choke because in the middle of a mission critical process there's an unexpected malware scan, OS patch assessment, etc going on.
When going onstage, I just prefer dedicated hardware. Turning off services in a computer's OS sounds like a recipe for an embarrassing moment thanks to process latency on an idiotic background service.

Anyhow, hope the idea gets  someone's head scratching who has not only better chops than I have, can assess the engineering side of things.

One last note..

I can't thank Elantric and Senior Members enough for getting me up and running on my GR55...
Love reading the articles and applying the results to my GR55.

Thanks to all.

All you describe is feasible .yet 10 milliseconds latency  will be added due to wireless ethernet AVB Wireless .

QuoteBeing raised in a house full of latest pop hits 1955-1975  - Myself - my ears and perspective were always attuned to the evolving sounds of Guitars, From 1953 Les Paul half speed recording techniques, to Scotty Moore slap back echo on Elvis hits, to Reverb drenched Surf instrumentals, to Beatles Paperback Writer, to Jeff Beck & Yardbirds "Heart full of soul", to Leslie speaker Clapton Solos on Cream's "Badge", to Hendrix's "Purple haze / All along the Watch Tower"  "How DID they  get THAT guitar sound?  - I also was addicted to seeking new original tones for my guitar - which in this consumer  / facebook "Me Too" society of 2014 seems to be a viewpoint held by a minority. 

I encourage everyone go out and "Create Disturbance in someones mind"

Indeed!!!!! Who told Clapton to play through a Leslie, or Beck to ram his headstock right into a speaker
( which I remember seeing a picture of in a teen magazine around '65, or so), etc. ? You either want to be an innovator or a follower. It's necessary to start with what you've heard that you like, but if you wish to make some noise in this crowded guitar world, you had better open your mind to experimentation. For my own selfish interests, I don't care if the majority spends their musical life searching for the perfect blues tone, in fact I see this as an opportunity to stand out in the crowd. So.... I LOVE the niche products, as they provide a more inventive palette, for the innovators to utilize, and  I only wish them to be popular enough to continue, not dominate the market. Hats off to you guys who continue what Roland has started!!!!

Pete,
Gumtown has a really nice game-changing ultimate project in his mind that would allow 13-pin guitars use a regular guitar cable, or transmit 13-pin wirelessly. It's really advanced stuff.

Look at the Beatbuddy team (www.myBeatBuddy.com), a crowd financed project. Their marketing is very professional all they way through.
Yesterday I was actually on Facebook when suddenly got an add from Beatbuddy with info about a pre-order deal (yup FB know my interests). I immediately pre-ordered a unit as I already knew about the project. I was impressed by their customized payment process in PayPal. Very slick. They claim to have 9000 units pre-ordered. This is modern thinking. Love it. I hope I eventually receive a pedal also...
But I got more gear than I need...and I like it!

Thanks for the info guys.
The 10 millisecond delay with Ethernet wireless as part of the overhead is more than I thought.
My guess would be that any other solution for wireless brings about the cost of certification mentioned in earlier posts.

It would be nice to see what the mention of Gumtown's project would be.
I will continue reading.

The A/D conversion is performed inside the GK Processor


these opportunities exist for Raspberry PI audio 8 in / 8 out processing
