The Yamaha AN1x Synthesizer mailing list

hello everyone! as a matter of fact i still don't have an1 but i saw it 
in a store and after getting some info on the net i'm seriosly 
concerning of bying this unit (maybe after 10days- you see i'm really 
anxious about that:). well i'm affraid it's condition is pretty poor 
(well, the price is about 300$)- it seems the original owner was really 
expressive person:) but after all the sound is important isn't it..
so here is my question: i found out that there is 128 ready-to-use 
patches, but actually i heard only a few of them. the most of the 
programs was named "initial brass" or "initial electric piano". please 
tell me is there a way to restore the factory patches and if no where 
can i find/dowload the original set of presets of yamaha an1. 
in addition of that i will appreciate any explainations of which 
editor/librarian to use when loading new sounds in an1 and how exactly 
to do that.
many thanks in advance for cooperation and undarstanding!!!
