Thanks for the answers!
Actually, I can use two stereo output from the virus with my current setup which is still not bad at all

I have a total of 3 stereo in on my soundcard but I use the 3rd for my jp-8080...However, I will experiment with the Ext In of the virus in the next few days

Maybe I could plug the jp8080 in the virus in and then use all 3 stereo out of the virus!
