The Yamaha AN1x Synthesizer mailing list

"Is there a possibility to disable this f....ng Ribbon Controller on
the left side?
I play for a while and then the sound gets like interrupted (short,
without release) till I press some times the Ribbon (I heard that I
have to press on the right side-above) and then I can play for a
while till it comes again. And again, and again...."

If the ribbon controller does this on its own, you've never touched the 
ribbon controller, then your ribbon controller is broken.

Also--the AN1X is not analog. It is a virtual analog synthesizer. It's 
modeled on the Prophet 5. Since Dave Smith both designed the Prophet 5 
and worked on Yamaha's physical modeling team for awhile, the AN1X 
sounds a lot like an old Prophet. It's all micro chips. This is 
actually better than analog as you get a nice stepping effect when you 
adjust the filter and at times you can get nice aliasing 
effects.Unfortunately, unlike analog, the AN1X stays in tune unless you 
program the tuning to drift.
