I have a Voyager Performer Edition, bought new last year, mint conditions. All of a sudden the glide does not work anymore: what can it be? Switch works fine (can see it turning ON / OFF on display) but when ON then the pitch remains constant across the whole keyboard. Can this be a software issue or some condenser just gone bad? Any Panel / Master setting I may have changed and stored wrong values with? Should I reset the machine? Basically any patch using glide will play the same note, same pitch on all keys, no matter what key I press. Any help appreciated, thanks.
