OT: audio to midi converter

[jayrope <jrploopers@kliklak.net>]

hello all,

i am trying to find an audio to midi hardware convertor for a guitar, which
is tuned down almost into the bass range (starting at F1 - highest notes
around F5)
for this project
http://txp.kliklak.net/artist/scenic-panner
which has music controlling a panning image display.

we currently use midingsolo, linux based software audio 2 midi
ttp://home.gna.org/midingsolo/
but there's loads of issues in correct pitch recognition, not to speak of
something like a polyphone version of this.

can anyone recommend stanalone units or other softwares, preferrably for 
the
linux or window platform.

muchas gracias!
jayrope
