I really love these MIDI effects in SX. Is there any way of d/ling more presets for them?

I especially like the Step Sequencer and Transformer (although I can't seem to get The Step Sequencer working properly at the mo as my keyboard keys seem to change the presets when I hit a key - ideas/advice anyone?)

I there any other ways anyone know of creating interesting ways of putting in notes in MIDI via SX?
