The Yamaha AN1x Synthesizer mailing list

hi,
I own an1x few years now and would like to know if the architecture 
of the plug-in board differs anyhow from the an1x? I know it has some 
new features (like new routings and cross-mod- BTW how does work on 
the board?), but what I really would like to know is, does the plg150-
an have different DSP chips that make it sound DIFFRENT comparing to 
AN1x? I'm not asking what you THINK listening to both; I'd like to 
know how it IS.
