Hi Brian,

I have tried the transform multiplication, which is basically the convolution of two samples. It is very time 
consuming and tends to be rather hit and miss. I have found that it is much faster to load wav samples 
into a mathematics program such as Matlab and do the convolution on the computer. There does not seem 
to be anything much of a sonic difference between doing this on a PC or on the 16 bit Emax II. I noticed 
that I need to renormalise the sample after the convolution on the PC but the Emu seems to take care of 
this itself. The Emax SE may sound a bit different due to the 8 bit compression but I do not have one to 
try it.
