The Yamaha AN1x Synthesizer mailing list

Hello!

I have bought used AN1x and would like to check when it was produced. 
How can I check it (when I turn AN1x ON, I can see 1997 on the LCD, 
but maybe it's only the welcome screen info - so date is as the 
beginning od production of AN1xs...).

And secondly... I have heard about some minor bug with An1x produced 
in 1997 (some click and crashes in vioces in DUAL mode). Does it 
happen to all AN1x produced in 1997??

Thanks for help!
