I have an ASR-10, ASR-X and a Groovebox all running with Cakewalk 6.0 as the master sequencer. I have a dual midi port (ie. two ins and two outs) whereby the X & the 10 are linked up.

I tried to connect the groovebox midi thru from the ASR-10 to midi in on the groovebox. I want to be able to use midi channels 1-8 on port 1 for the ASR-10 and channels 9-16 also on port 1 for the groovebox (midi thru) What happens is that the ASR-10 is sending all midi info received on channels 1-8 to the groovebox, therefore the groovebox is playing midi messages that are only intended for the ASR-10.

How do I stop this?
