Luka,

I'll try to answer your questions...
(1) SD1 comes with 16 harmonizer presets in memory called Vocal Sets. In addition, unlimited number of Vocal Sets can be created and saved in it's internal hard disk.
(2) Yes.
(3) SD1 supports up to 4 layered sounds using their Program Sounds. Each sound can react to different controllers. It can faded in or out with a volume pedal, or respond to sustain & pitchbend differently. For example, My Piano/String combo would have sustain on piano only and volume pedal on string only. So the string can fade in and out and my piano sustain does not affect the string.
