Ot changes pattern on MD

hi folks,

there is something that I really like to do, but i dont know where to start …

i have Pattern H8 H9 and H10 on my machinedrum and want to control which pattern is selected with the OT

how to change my MD patterns through the OT

reason:

i dont like song mode on MD because the display is halfed.

I need to use the ctrl machines on different patterns, but changing pattern by hand, sometimes my hands are not fast enough, or too busy.

chaining patterns also is not an option, because i dont want a strict abc abc abc, more like abb acb bcc bca acb cab bca and so on…

thanks for all suggestions
