A system trying to interface between guitar and synth style processing seems to be exactly what I am trying to build myself.
After checking searches, I stumbled upon a comment from one people who worked on the project, "I liked Pure data, but I don't like using computers", so exactly what's in the box, who knows..
Personally, I don't think its a game changer, but it does provide an interface into the synth world for guitarists. Which was a direction I read many other comments would take.
But one thing I have learnt in my own build, this is not so much about applying an effect, or many effects, but more about a complete performance. But this can also be a problem, yes this system will provide sequencing and looping options etc, but for performing guitarists, I don't think this is very desirable. For years guitarists can already have complete backing bands in a box to play along and or perform with, an easy way to earn a few bucks on the side, isn't a system like this just swapping out the backing band for synth style triggering of effects and loops etc.. ?
I know above may seem rather convoluted, I do believe that if you are interfacing an instrument, every pluck of the string can provide its own expression, and its extremely important to capture this within whatever system is designed.
Sure there is probably plenty of places for some sequencing, lopping and effects etc, when playing your guitar, but to have it naturally change in feel to what you are playing is really the holy grail.
One thing I have discovered to do on the Axo, is if I pluck my string harder then normal, it can trigger an event, at the moment its just a simple synth sound through an ADSR, but the concept works. I can also have it trigger a midi drum sound, its fast enough to detect quite fast picking. But the best thing, is I can spontaneously choose to pick soft or hard, trigger or not trigger.
Note.. I will make the object to detect a string pluck available soon, but it is very crude, and I am not sure if there is something I am missing.
