I made some stuff for Teemu 1.3 and the week started nicely, but then I was distracted by setting up a DAW for music making. From the demos I tried I liked Ableton and actually found a Lite version from my M-Audio keyboard package. So it didn't even cost me anything. There is a hard limit of 8 max tracks (or instruments) but if you keep things simple it might be enough.
I think I'm going to continue with Teemu, because it was a good start towards version 1.3.
