Why is the compression the best on the 303? is it the same sound engine as the 404? And can ppl rip these engines out and sell them on ebay with out the Manufactured sound engine?

what im saying is can they rip the stock sound engine out of the 303, replace it with a ghettoFIED one and sell it on ebay ???

hmmm. good question, i doubt it. it would require a different motherboard which probably wouldn't fit in the 303's chassis. but, as with some samplers i've gotten off of ebay, they can have little faults within them that weren't known at the time of purchase. it's always important to ask the seller as many questions as possible before you buy.
