Yeah, that's what I've been touching on....
Someone else is going to do a "MIDI" pickup that is audio-only, and does the conversion elsewhere.
* Cheaper pickup, so you can put it on my guitars, easier to replace
* Smaller, easier to embed in the guitar
* Offloading the conversion means you might leverage more CPU/DSP for MIDI conversion (if that's even needed, not sure), and the conversion is applicable to ANYTHING that is sending raw audio into it.
Never got into the 13-pin stuff, but I have this vague memory that it kind of worked this way as well? I.e., audio-only coming off the guitar?
Also, 32 channels means someone is going to re-invent the controls on a guitar; more than enough to send volume, tone, etc.
Even better to merge the mag pickups into the same cable -- more than enough channels to do all this.
