I recently purchased my second ds-2 hoping to get 1 of the two to work.
Im having two issues.First I can t get the notes to track correctly,
It wont play a note up from the note im holding or follow fast
runs.Every note plays the correct pitch but if i play fast or "smear"
notes it wont follow them or slide up to the note I play whil holding
another.Second problem has occured on both ds-2 i own. the resonance
funtion does not work at all.If I turn it up and release a note it
just sounds the low f key everytime no matter what.I have been
swapping chips and parts like nuts.Both of my ds-2's suffered from
dried up pwr supply caps but came to life once they were replaced.I am
willing to help someone out with some spare parts if they can help me
out with my problem.
