Possible...? - Updating/improving my keyboard sound palette ?

[Dave Simmons]

Hi. - For a long time now I've been enquiring about trying to do something about my keyboard/elctric piano sounds.
I have absolutely no funds available..
( I'm long term unemployed ) to purchase anything, but wonder whether there might be any freeware/shareware options.
I have a Yamaha PSR 310 keybaord, and I use Logic Audio Platinum 8.0/D-Man PCI 2in-2out sound card/Berringer Eurorack 4 channel mixer/DBX Project 1 Pre-amp.
I am Midi-iliterate.
Might anyone have suggests re some good Jazz fusion electric piano sounds that I might somehow be able to access, plug in and use ?

cheers Dave.
