I just saw this post of yours and my questions are off-topic.
I have been thinking for a long time of trying a hexaphonic pickup on a guitar
and using something like Faust to process the outputs. One area that interests
me is eliminating the intermodulation distortion between strings when using a
nonlinear effect so that non-major chords played through a fuzz-type device
don’t turn into nasty near-white noise.
So the obvious question is: what is the crosstalk between the six channels, or
put in more audio-like terms, what is the channel separation between the six?
Also, is the pickup linear? If the pickup is linear then the crosstalk could be
described by a symmetric 6x6 matrix of transfer functions with ones on the
diagonal and it would be possible to build a crosstalk canceller to reduce the
crosstalk if it is too high.
I listened to your HexFuzz demo and if I am interpreting what I hear correctly
the channel separation is pretty good since it seems that each string’s fuzz
distortion does not mix much with the other strings. The effect that I hear is
awesome!
Also, what do you use for a sound card or external digitizer? Do you use a
computer or have you ported to standalone hardware?
Thanks for any comments at all.
Jerry
