this is a cross post from vintage synth - someone recommended i post the same question here so... here we go:
my cs-60 is in pretty good condition but there's an indentation in the ribbon controller - this means you cannot "press any position as a starting point" - the only starting point on the ribbon controller is where the indentation is - i noticed the lid for the cs-60 has a support that holds the lid away from the controls - the support rests right on top of the ribbon controller in the indented spot! is this a design flaw? did someone put this particular lid together wrong? should i only use the lid during transport? remove the support? does the cs-80 lid have this issue too?
also... how hard is it to fix the ribbon controller in this state?
