[sdiy] Retrofitting a PS-3100 with an Arduino

[Mattias Rickardsson]

Sounds like a good solution, and you seem to be reasonably skilled tech -
so why not go ahead? :-)

Best,

     Â  Â hello list!
     Â  Â first post here, - hello!Ã
     Â  Â I recently managed to acquire a PS-3100 in great condition. it
     is fully
     Â  Â operational, and i've been having a lot of fun tracking with
     it, it is
     Â  Â an immensely powerful instrument!
     Â  Â i couldn't help myself but open up the back panel right away,
     and
     Â  Â happened to have a midi controlled "gate" sketch uploaded on
        myà arduinoà MEGA on my workdesk(each pin going HIGH on
     corresponding
     Â  Â note ON message received).
     Â  Â looking through the PS-3100 service manual it looks like I need
     10V
     Â  Â gate signals to trigger each individual note - i put together a
     simple
        single transistor configuration to expand the arduinoà logic up
     to 10v
     Â  Â - alligator clipped a few pins to the inside of the 60pin honda
     Â  Â connector... lo and behold!! I could trigger a few notes on the
     PS-3100
     Â  Â from Ableton within 45 minutes!
     Â  Â so my question is - rather than purchasing the rather expensive
     Kenton
     Â  Â kit (i don't need CC messages, for now....) is there any reason
     at all
     Â  Â why installing the Arduino with 48 simple 10V transistor gates
     could be
     Â  Â a bad idea, or potentially dangerous to the instrument?
     Â  Â it seems like it could be the most minimally invasive procedure
     Â  Â available for these keyboards....
     Â  Â thanks for reading...!
     Â  Â all the best,
