Hello,

I have Yamaha Dtxpress drum machine that does not trigger on two of its
inputs. Stumbling around with a scope without a schematic is rather trying.
Does anyone know where I could get a schematic or have a hint as where the
problem could be? The inputs that do not work are 1(Kick) and 3 (Tom1)
