Hey John,

May not be an exact match but should be pretty close. You can download the tech data sheet for SD40 from our site that has bank and patch info here --> https://immusic.co/wp-content/uploads/2018/05/SD40_Technical_Table_2016.pdf
We also have an *.ins file that works with Cakewalk (or Sonar) that will map out the bank and patch commands should by any chance you have access to that DAW?
