I think I understand your problem, the solution requires a bit of re-programming:

Make sure the number of rows and length sync up. So if you have:

OT

  1. pattern C12 16steps
  2. loop 2x

make the slave:

MM

  1. pattern C12 16steps
  2. pattern C12 16 steps

instead of:

OT

  1. pattern C12 16steps
  2. loop 2x

make the slave:

MM

  1. pattern C12 32steps
  2. Error :wink:

Hope this is clear?

EDIT: stuff gets fun and fuzzy when you create nested loops, set different BPM values and tempo divisions!
