Hi all and thanks for chiming in on this thread. There was once, long ago, a simple mixer which dynamically created the busses and channels. If anyone can remember that one, it must have been 5 years ago, and was the first dynamic patch I had ever seen.
Also fun, non-utilitarian ones, like once someone sent some kind of "card" to the list which just made a huge self-generating GUI art-mess on the screen. I wish I could remember who wrote it. Lastly, IOhannes showed a very nice self-modifying patch at Piksel last December using iemguts.
best! Derek
