Ensoniq EPS classic stereo bussing

Ive been seeing the OEX 8 and OEX 6 output expanders recently, and they are WAY out of my price range, just so i can bus my layers and instruments in the Ensoniq eps classic. I see how they work though, i just cant find anything on them for the EPS classic in specific, only the ASR, which they have different output settings. Is there any way i could at least get 1 more channel by panning the layers or instruments to left/right?
