humm... I guess what ever workz 4 ya really... I would stick all sample playing inst. with in SX/ Logic enviorment.. well in fact really depends if u like or not the sound of each instrument.. I mean sometimes a little noise or distortion is what gives character 2 yer sound...
So I would probably move 2 a "bigger boy" and get some really good virtual instruments and some exelent plug ins! :)
