I guess I mostly get 1 wav smaller than 1.4meg ... and load into hard drive ..then I load Coustom Banks.

Also Since you have MIC imput on PSR ...you could go from OUTPUT of Sound CARD on PC into PRS9000 and switch to LINE (3rd position on mic input) on PSR!
You can Play the wav's on Computer and instead of Sampling your mic ... record the PC WAVE directly into Sampler!
Make 64 meg WAV folders and then Load in Costum BanK!
