“This is a FAULTY Yamaha FB01 – 4 operator FM synth sound module.
I got this in a job lot of random kit about a decade ago and it never worked properly. You turn it on, it says ‘FB-01 Ready’ on the screen and then it changes to the ‘[17] Single’ screen shown and nothing happens. None of the panel buttons have any effect and it doesn’t respond to midi. God knows whats wrong with it, but i’m moving house soon and just need to get rid of some junk. Maybe i’m just missing something obvious…
Other than just not working its in pretty good condition.” Click here to visit listing on eBay
