Jimmy,
I've been playing keyboards since I was a young lad. My musical style is somewhere between Keith Jarrett and world music with some classical thrown in for fun. I just sequence my own music for kicks. With my current setup I'm using a Duo - Quad Core Mac Pro with 10GB of RAM running Logic Pro. I was using a Digi002 but found Pro Tools to have latency issues with my large plug-ins from EWQL. After making the switch to Logic Pro I now port everything through a Lynx Aurora 8 AD/DA converter and don't have those kinds of problems anymore. My next goal is to eventually set up a nice sized tank, film it, and put music to it. I did this with my current 28G tank in this thread:

But I only spent about an hour putting together the music as I wanted to see what the video would actually look like on Youtube and was a bit impatient.
Sorry for the drift into another hobby...Back to your Tank and Stand, which looks really good.
