E-Mu B-3 module or Rom?

[somecallmetim]

Does anyone know if there is a difference between the two?
I have a PK-6 that I was going to add the B-3 Rom to, but may have a line on a cheap E-Mu B-3 rack Module.

Does having the rack module give me any more control than plugging the rom in my PK-6.

Thanks for any replies!

not really, and if i recall corectly, you dont have the preset buttons on the rack module. the only diffrence is if you get the rom card, the knobs may be labled a little wrong. ive got the vintage keys rom in my pk6 and its like that.
thats it really
