Hi all 

    I am having a few problems with a recently purchased ds-2.I cannot
get the poly to work right,It stays in mono mode and always has the
lowest key sounding.The other notes work ,but as soon as notes are
released it goes back to the lowest note!!?? Also the release of the
adsr circuit does the same thing it just sounds the lowest note.the
high pass and low pass circuit does nothing in poly mode either.Also
there is significant popping in the vcf and vca circuits heard at the
initial attack of all notes.I have changed all but one of the power
supply caps and a few opamps and the only result is less noise and
crackles.I am at a loss as to what to check for, any ideas?
                    thanks Joshua
