Thank you. I appreciate the advice. I'll give up on trying to reroute it. I was afraid I couldn't do that.

I adjusted the tone wheel over the entire range. To tell you the truth, it doesn't even seem to affect the volume output at all. I'm even uncertain what is the "start" position, but I'm presuming the far counter-clockwise..

Last night I was extremely careful and tried to moniter it religiously. I gig 4 nights a week here in Toronto. I kept the volume very low on the mic plugged into the vocalizer and my second mic I had a my direct main into the mixer. That one I had normal volume and regular channel reverb with the mixer. No issues, great sound.

The Ketron vocalizer is all over the place with levels when the midi files come in and it doesn't seem related to obvious things like the volume on the track alone. I have one song that it came blasting in almost double the volume of my mic even with the slider a quarter of the way up. Then the slightest pull down and the voices disappear! I had to move it more then double the way up on the slider to get it to the proper level after that which was still much less then how it blasted in. This would repeat many times during the song as the chorus was the only place it came on again.

This is the best example of the main problem even now without using the channel even as the primary mic. As I said in the OP, it's disappointing and I was at least hoping to isolate the channel. For now I'm going to get the Radial JS2 to split the mic so I won't need two and then I'll either jury rig the Voicetron as best as I can for these known issues or eventually find a better third party one. I heard good things about the TC Helicon.

Just want to explain all these issues very clearly for others so they will be prepared if they choose these products.

I am extremely pleased with the instrument quality. Pity this one specific issue with vocals has to be so difficult to get around.
