Note from Gilbert:

The tse3-0.2.7-patch-gcc3.4.diff is for compatibilty with gcc-3.4

I used the tse3-0.2.7-patch-alsa1.0.diff in my build. But the
tse3_alsa1.x_and_sustain.patch may be better (may contain an extra fix).
Try using the alternate if you like...

The tse src.rpm and the x_sustain.patch are from a site called
Virtual Main.
The tse3-0.2.7* patches are from the noteedit-2.8.1 sources from berlios.
They are both contained in the tse3-patches-1.tar.gz archive.
