That's a shame that you were let down my your musician. Is that the one from Freebasic.net? Zamaster? Hope he's ok, he seemed keen to help out at first.
Glad you've stuck the lib in the archive, that will definately mean that more people will see it.
There were a lot of parts to this demo that I liked, having watched it a few times now I can tell you that it also contains two parts that I wouldn't know how to code

This is a first for you and it shows me just how far you have come as a coder.
By the way, the demo runs very smooth here with nary a frame lost throughout. Well done.
I will be updating the showcase this weekend I think.
