Rhodes Chroma Polaris

I have had failed membrane buttons (not ribbon cable) on 1 of my
polaris keyboards.  I've described the fix on this group-- drilling
panel and replacing w/pushbutton switchs.  It is a time consuming
process, a drill press and hot-tweezer wire stripper are highly
recommended.

Sometimes the honk happens from sequencer events-- I would check the
manual and make sure it is truned off.
