I took a few hours yesterday with some down time to investigate my S970 fuhrer and dig into the OS a bit to try and satisfy myself with an alternative Mic/Voc processor/VH2/ Live Knobs setup that I was happy with and possibly use it if I had to on a very small gig vs my current setup though my Mixer. YOU really have to dig in and set up your gain at Pre maximum distortion and really tweak the heck out of the setting types and levels to get a decent FX on your voice. I found that the standard trio & country VH types work pretty good. NO where as good as TC Helicon/Digitec units but surprisingly better then previous Yamaha VH processors that I had in the past...its possible they worked on this and improved Vh2 a bit in the S970 as tracking is a bit better and now usable also. I set the Live Knobs at #1- Audio level....#2- Mic/VH level for now which gives my full real time control over the volume of each independently every little bit of navigational independence helps with each model released..
