It is a decent graphical interface to the VS880.
It's a so-so sequencer. I think it's strength is
the effects editing. The little, ridiculous, screen
on the vs880 makes it cumersome to do anything
without having to scroll through the pararmeters.
VSPro puts everything on the computer monitor.
It works with approx 20 effects, but you can save
your own to User presets. Tech support is good.
They answer your question via email pretty quick.
There's another program called the Virtualizer.
The guys email is
lberinger@biamp.com, he'll send you a copy.
It's buggy and doesn't work with NT or 2K, to my knowledge.
It'll only work with one MIDI device at a time.
You're going to need a certain amount of patience
to get this one working, but some people rave about it.
Go to vsplanet.com and check out Virtualizer.
Or you can hike up the arduous learning curve of Logic VS.
