SH-01a- disabling midi pattern out signal?

Hello-

I’m trying to figure out how to disable the midi pattern being sent out from my Roland SH-01a. I am using with the K-25M keyboard controller and trying to use the midi out to control my external waldorf streichfett. It works great, accept when I have a pattern playing on the SH-01a its also sending that pattern signal to my waldorf, which I would like to have disabled so I can independently play over the pattern.

Any ideas how to disable the pattern out whilst still keeping the midi enabled so I can play notes? :slight_smile:

Feels like a lost cause and I’ll have to just buy a separate midi controller, but I’m loving the minimal K-25M setup.

Thanks in advance!
