This is very exciting news! Sorry I didn't see this sooner, but I don't check this board nearly as often as I should.
I had a look at it and listened a number of sequences, and whilst there were a few that either didn't play (or stopped mid-way), for the most part it functions well.
I'm interested to see where this project ends up, but right now I feel like a kid on Christmas. Thanks for all the hard work, double-so for the simplicity of the tool.
