well, its not because it doesnt sound like a 60, you cant use it. i use it alot on drums, its not the famous 12bit sound, but its something else and if you like it, you like it! the samplefreq is verry nice. with this conversion you van save some memory wich is handy if you work on floppy's. just experiment with it, but be aware of the slow convert-time! if u experiment, i suggest you try small sounds (MAX100kb), so you can hear what it does without waiting a verry long time...
have fun with it, its a nice feature!
