The range has to be 1 to 80 because 0 velocity = Note Off. You also don't specify which note is the one that triggers the operation (you only mention velocity ranges and resulting note), but assuming it is C#2, I've attached something that does that. It's a bit tricky to achieve cleanly.

That did it perfectly so how would i change it to another not for example G1 instead of C#2 for the trigger input and a different resulting note.....say D1 instead of D#1 ..........G1 to D1 same velocity splits?
I see you have a split note on off object, two velocity split objects and a resulting object
all are transformers How does each function sorry to ask for so much detail but if I understand this fully Ill be able to trouble shoot better myself in the future
