I use the Alesis multimix 8 usb 1.1 as a small mixer to mix my 2 Yamaha modules together. I find this mixer to be a great tool for me, ultimately I would like the usb 2.0 Multimix 16 but I dont have the cash for it but thats the goal. I really cant say enough good things about most of alesis's products, dollar for dollar they pack a great value into everything they make.
