Hi,

I am trying to transfer songs recorded on the Yamaha P155 using a USB Storage device to a Macintosh computer. Unfortunately Yamaha mention the keyboard's documentation that to accomplish transferring songs between a computer and a P155 keyboard using a USB storage device one must install their "Musicsoft Donwload Software" which is only available for Windows PC.

Hi,

As i know, most of the USB audio interface in 2 channel input. But nowadays, there are a lot of USB audio interface or even a USB Mixer comes with more than 2 channel inputs. In this case, do it means c'ld recording in Multitrack like what Firewire Audio Interface did? or, it still a Master Stereo Channel on USB recording? Thanks for explaination with appreciation.
