I've been reading up on A2M technology and I think I've made a breakthru. This prototype only works with 5-Pin DIN midi (actually, only pre-'83 midi), but latency is 525 femtoseconds or less. And its bus powered. And since 5-pin midi is optocoupled, this improves intonation.
-->> and this is where the pic of a MIDI cable spliced to a 1/4" guitar cord is shown... <<---
After this is tested (still waiting on the iron to heat up) I'll try a USB version.
