there are some dutch dudes who do a yellow thing in a rack that sounds brilliant .... i don't think it was the freebass one though, called something else ... can't remember what the **** it was tho. sounded well nice.
we had an MC303, lent it to a mates kids now, if anyone wants the drum sounds i sampled most of them. there's a couple of handy noises in there.
mc505 has some good drum sounds too, if anyone has all the claps sampled up off this thing I'd love them :)
