I also bought mine sight unseen. I would say you should definitely get the keyboard verision, it really adds to the whole instrument feel. The touchpad is great, too.
Maybe I should just buy all 3!!
Now your thinking! Hey, your profile says you are an attorney, you can afford it 
Forget the RME - get the keyboard.
Another thing you can do is use the Voyager as a midi controler to control a digital synth module and run it through the Voyager’s filters and EG’s. That way you can get some sort of fake poly going on.
The Voyager’s filters make just about anything sound bitchen/warm/analog/________.

Congrats on the decision. I’ve always felt that owning a Voyager is a bit like having a Porsche (or insert name of your preferred fantasy car here) in the driveway. It may not be your ‘daily driver’, but you always take great personal satisfaction in owning one.
<< and I am fascinated by the touch pad. >>
The Touch Surface seems to get a mixed reaction from Voyager owners. Some really love it, some dislike it, and some are just neutral about it. Regardless, consider it a nice extra form of control that’s built into a great instrument.

Nah, you’ll just make the rest of us jealous!
