[sdiy] Yamaha CS80, pedal inputs non standard

[Peter M Blackett]

Dear Lincoln ,
the pedal inputs aren't a standard potential divider ......
the original pedals have a small bulb and a ldr , so if you plug in a
mono jack plug you will [ I think ] short out one of the supply
voltages.
[not a good idea ! ]
from what I can remember you don't need to have a pedal plugged in to
get the synth to work.
regards Peter
