My beloved Akai MX1000 has the PM76 piano board in it. Seems quite rare. Apparently the sounds are from the S1000 library, but I've not been able to find them there. Anybody recognise them? There are 10 in total, I've recorded 5 here.

It would be fun to source the original Akai S1000 library sounds!

Don't know. I expect you've probably got the same sources that I have, so if you haven't found them there, I probably won't have them either.

You could just resample them out of the MX of course!

In a strange co-incidence, I'm proofing the MX1000 review from SOS Mar '92 as we speak..!

Oh great! Nice to have another reference. I just finished replacing the inverter/ EL foil with an iPhone 6+ backlight. So I can program it again. Can’t believe how old this keyboard is! It’s fun to keep it going.
