        @Christoph-Hart got it going!... Is there a way to change the note position instead of transposing them?

          Yeah, sure, just adjust the timestamp.

            So I did... (and I may be way off with this)

            if(note.isNoteOn())
                note.setTimestamp(Math.randInt(3, 6));
            

            but it just stretched them all from the start point.

              note.setTimestamp(note.getTimestamp() + Math.randInt(3, 6));

              But unless you have super powers, you won't hear the timing differences of 0.00015 seconds :)

                Haha... Thank you, I got it rolling now! With a more realistic timing difference.

                  Is it possible to kind of add a more predictable randomization to the notes?
                  like set the transpose to go up or down 12st (nothing in between) or shift the notes forward or back a certain amount? Or an I asking for to much lol?

                  Ive been trying to figure out how the seconds (EX.(-200000.50000, 0.50000)) work and how I could use that to accomplish my goal.

                    Up or down 12st:

                    Message.setTransposeAmount(Math.random() > 0.5 ? 12 : -12);
                    

                    The timestamp unit is sample rate, so you need to use Engine.getMillisecondsForSamples() to get the second amount (there are also other conversion functions in the Engine object that you can use to get tempo based values.
