Deane,
Again thanks for the recordings and for your input, but I know little or nothing about vArranger, so a few questions:

How good is vArranger without the SD2?
Can I play T-4 styles using vArranger hooked with an S910?
How much does vArranger cost? Is there a free trial?
Is vArranger compatible with an IPad?
Finally what is the cost of an SD2?

sorry...lots of questions, if you or anyone has time to answer, I'd appreciate it.
