I was working on a few more pipes for the organ last week, when suddenly I had a brainwave. "I'll bet the pipes would work a lot better if I did them like this," thought I. So I tried it, and they did.
The only problem is that all the other pipes are obsolete. I now have 80+ pipes that I either need to take apart and reassemble in the new way, or simply replace altogether. In short- back at square one. A better informed square one, but square one nonetheless. I need to stop having ideas.
