What on earth is the groove box?
Only the best of the best club dancers in all of South Beach; a real all-night party girl. So I guess that you'll have to come to South Florida to get her. I don't think she's downloadable, though, but once I did have the pleasure of uploading her. Don't attempt this manuever riding 'bareback'; bring the proper safety equipment.
Seriously, Charles, we have the Groove Player that comes with Project5, the GrooveSynth from Kinetic (and apparently in the upcoming version 2 of P5); neither of which are downloadable. The only other thing that I can think of is the
Roland SP-606 sampling workstation, which is also known as the Groovebox.
Here in the Download section at the Roland site, you'll find the latest [1.0.0 for Windows; 2.0.1 for Mac] drivers for the unit. I'll have to check with Marcella, but since the unit is a combination of hardware and software, you'd have to have some serious bandwidth to download the whole package. <g>
OK, Charles, let me apologize: the boys and I are having a little fun at your expense. We really do want to help. Please post again with a more detailed description of what it is that you're after, and I'll do my best to help you out.
