[sdiy] roland sh-2000

[Finlay Shakespeare]

Hey Jakob,
That sounds to me like something's wrong with the VCA section along the 
line - it isn't closing properly and is letting a little signal bleed 
through. That could be sorted by tweaking a trimpot - can you see any little 
preset pots on the VCA board?
It seems a little odd to me that Roland would keep the pitch high as a 
standard... but I guess it's easier to have a high pitch all the time then 
add resistance to it to drop it.
Cheers,
Finlay Shakespeare
