Hello all!

I've owned my Polaris forever but it's spent almost all of the last decade in storage.  I recently pulled it out with the intent of selling it, but it's developed some issues I'm hoping you folks might have some thoughts on.

The first is the ultra-common one: bad membrane switches.  I tried to fix them myself but have only succeeded in making the situation worse.  Are new ones available?  Google yielded some references to someone selling them several years ago but I didn't see anything recent.

The other problem it's having is really weird.  As soon as you connect the MIDI output to something, there's a click in the audio output every time you hit or release a key or move a slider.  I think basically it's making a click every time data is sent out the MIDI port.  Has anyone else seen this problem?  I'm thinking it could be a decoupling cap issue but I have no idea where to look.  It's not a ground loop because it does it when connected to a laptop computer that's not connected to anything else.

Thanks in advance for any thoughts!
