JX-3P a      JX-3P b

The Roland JX-3P had good strings as I remember.  It was also an un-synthesizer as I remember too.  When you bought the keyboard there was no way to program sounds... unless of course you bought the PG-200 add on.  Well... needless to say it was OK.  I just didn't like the fact it was a $800 casio.  But there are some good sounds here for you... I'll save you some money.  There are 21 sounds here which are only a few less than originally came with it.  Click on either JX-3Pa or JX-3Pb to download the soundfont.
