Hi all, forgive me if this isn't the correct group for such a
simple question. If its not the right newsgroupe please kindly
redirect me to the appropriate group.

I'm planning on building a homebrew midi guitar, and i am
wondering what the best thing to use for a pickup is. I'm new
to electronics, i think i can manage to build the midi
controller with a pic chip. What I wanna do is monitor 6
analog sensors (one for each string) and send the
velocity/amplitude info out as a midi note..

I plan to use regular guitar strings, shortened, with no fret,
so that they produce the same note. I'm thinking one piezo
disk for each string, with a filter on each to recieve only
the note produced by that string to prevent cross talk, but is
there something better I could use? Hall effect sensors?
electret mics? Any advice would be greatly appreciated.
Ofcourse if anyone knows of any home brew midi guitar projects
links or info would be great. Thanks in advance for any info.

Roland makes a good off the shelf midi pickup. I believe it is the
GK3A. It also allows you to mix the MIDI signal with the pickups IIRC.

Thanks a lot for the reply, but I should also mention that I have no clue
how to play Guitar, and no honest desire to learn. What I'd like is to be
able to program the chords into the MCU, and trigger them by strumming.

I'm not sure a ready made midi pickup would work for this. I could try to
program the MCU to recieve the midi from the Roland, and then transpose it
to the desired chord, and then output it.. but that would require twice the
processor power.

The other problem I would have with that solution is price :)
