Hello...I'm having a problem with an e64. I used to own an e6400 where I could simply assign any midi channel an output pair : main, sub 1, sub2, or sub 3 in the master/multimode page. I could for example say that midi channel 1 should be preset 1 and then assign any output pair to that preset and midi channel all on the same page.

With the e64 its simply not working! I get sound out of the main outputs no matter what and other than that i only get sound out of sub 1. if i assign a prest to sub2 or sub 3 i get no sound from those outputs.

I've opened the machine up and the correct card is there with all outputs connected in the correct way. I'm hoping that I'm doing something wrong and there is no prolem with the machine itself, but from memory I'm doing exactly what I used to do on my e6400.

hope someone can help.....

Thanks,

Russ
