Herbie,
On the SD1 you can call up and play songs directly from the hard drive and you can arrange these songs in any order you like. There is also a demo and hit folder which allows you to have hundreds of songs in any order you want and by just hitting the button called demo and hit these songs become instantly available. The good thing about this is that you will not have to hit the button called song play and then hit directory function button and then scroll through and find the song you want to play. It's really fast using the demo and hit button.
There is also the ability to call up and play styles directly from the hard drive so if you have hundreds of great style customized or loaded in from vast libraries available, you do not have to stop to call up one of these hard drive styles.
The vocalizer in the SD1 allows for your voice to be used on all harmony voices or gender specific, including female, male, robot or other crazy voices.
there are 4 outputs on the SD1 so you can assign whatever you like to a live PA system for working situations.
