Lots of great suggestions guys! Short-scale may be an option - plus, my wife always wanted to learn to play bass, but a full size one would be way too big fore her. Getting one that we can both use would be terrific.
I'm currently using Scarbee most of the time, but, it's a drag to play realistically on the keyboard, considering that, being a guitarist, I could get the track nailed much more intuitively and quicker using the actual instrument. I entertain no illusion that I'd record
great bass lines, but, you know, just something that works and sits in the back nicely. It'd actually be easier to come up w/ something that flies under the radar than it is w/ sample and a keyboard - there's just a lot of work to achieve something that won't call attention to itself w/o being too repetitive or unnatural.
Plus, writing grooves on bass is so much fun. :P
