Voyagers, I have 2. Am I crazy?
Yes you are. Crazy like a fox.
He rides the same fine line I do…he just wobbles more. 
The only benefit I could see to having and OS and voyager is if you’re a really intense knob tweaker I’ve heard the OS is smoother when turning more than one knob, where as the voyager has a slight zipping/stepping when multitasking the knobs. So you can get two different modulation effects.
I own neither, and haven’t played a voyager in several years so I can’t confirm this. Anybody notice this or is it a myth?
I believe this was fixed in the latest OS update. The processor now remembers the last two knobs turned and dedicates more time to them. If you’ve got more than two hands you might have some trouble, but it’s probably good enough for most.
