i would like to know more about the processor upgrade. i have a s 770 sampler. the filters and warmth from that sampler is unbeatable even today!! i bought an akai s 6000 and the filters are really cold!! they cant compare. where did you hear about this processor from. i want one asap if one exist. it would be cool if the processor could allow you to read wav files or something. please e mail me back with more details at mikehuckaby@hotmail.com
