External midi device question

I have a Roland tone generator, i am using as 16 channels multitimbral mode.
I am using 3 midi track at the moment. 2 of them need audio effect. I create audio channel, use any kind of effect i like but this time the third midi track gets reverb too.
Is there anyway around this? I want only that 2 midi track gets reverb


Either use multiple outputs of your Roland hardware (if there are multiple outputs) or record the signal to the Audio track and apply the Insert effect here.

Thank you
