Thanks! I was using the Quattro when I did those cartoons. Now I have a Hardsid 4u. It works, however there are no mac drivers, which is a real pain for me. The interface works, but there's some basic functionality (copy and pasting of paramaters etc) that's missing. They say they basically do it as a hobby, and it's a very niche market, so they don't really do much in updates, etc.
That being said, if they made mac drivers for it, (which they did promise for some time and was the reason I originally upgraded to a 4u) with all the music that's made on macs (especially in the US) and all the interest in 8bit music of late, I think they would be able to recoup their costs and then some. But what do I know? I'm a freakin' trombone player.
All in all, it's the only hardware oriented device out there that has the flexibility for folks like me that want to do more with it than play sidtunes. With 4 chips installed that's 12 voices of SID! How incredibly over the top!!! And, there's much less noise from these things than from using a C64 directly. (and much less a mad science project, too...)
