Emax

Hi,
  I'm new to the list. My name is Michael, and I just got an EmaxII 
last week! After successfully installing a 540meg internal drive, 
I've decided to risk getting the 8meg ram board and stereo chips from 
a guy who is selling his EmaxII Turbo for parts.. Anyone have any 
suggestions for me? I figure if I've got the two boards side by side 
for comparison, I can figure out how to install it myself..
  Also, can someone direct me on how I would delete a sample from 
memory, thusly freeing up RAM? I'm trying to take a drum sample from 
one the drum banks I got with the keyboard, change the pitch down 24 
half steps, change the sample rate to 10000hz, and then change the 
pitch back up 24 half steps (this gives the drum sound a nice grungy  
crunch)..  But I'm always out of memory and I can't seem to figure 
out how to erase  _samples_ from memory (although I figured out how 
to erase presets).

Thanks,
  Michael
