Hi, No you can only have 8 instruments loaded into the memory, but there is a way a round the problem. Some instruments, like eg. bass you normally only play in the lower regions of the keyboard, right? Try to split the intrument and have that cool vocal sample or drumloop on the higher end of the keyboard. Since you can adress the waves them self to different FX buses you can then apply different FX to them (even better if you have multi outputs!)
Hope it helps, but that was the reason why I bought a ASRX so that I can load 16 ASR sounds into it, but I still keep the ASR10 since it so great.
