Hi,

Sorry to say the laws of physics haven't changed all that much yet. I 
think that has something to do with why the V-Bass didn't have a 
built-in MIDI out and appears to track so much better-- the attacks 
(at least) are derived from signal processing instead of pitch 
detection/resynthesis.

Nonetheless, the GI-20 tracks as well or better than any other 
pitch-to-midi device I've tried. It follows bends and slides nicely. 
 From the few days experience I have with it, I'm estimating it 
outputs a midi note after about 3 cycles. For the lowest note on my 
bass, that's 40 milliseconds which is an awfully long time to wait 
:-) But that's to be expected, and I am not even trying to use it for 
rhythmic attacks, but rather to trigger textural sounds that layer in 
with processed pickup signals.

Yes, it requires a GK-compatible pickup with the lovely little 13-pin 
DIN connectors. I took apart a GK-2B and rebuilt it to fit the string 
spacing on my upright, and it works great for pizz but not arco (it's 
a magnetic coil so no wonder), and I'm building a GK splitter/router 
box now. I'm hoping to try a Lightwave optical pickup soon.
