in which he said David Garibaldi from Tower of Power programmed it in the LM-1. What I don't know is if it was a stock preset, or if he happened to program it on one specific LM-1 and Prince got ahold of it at some point later and jacked it. Because it it was preprogrammed stock, this would be a much more known fact sincere anyone with a stock LM-1 would have that drum pattern.
Prince killed the bass guitar part on that song though...

it pays to check the main page regularly for such stories, yes.
Here's what the author, Elijah C. Watson, wrote:
"The track showed Prince’s prowess as a producer, with the song featuring some of his best work across various instruments (most notably the bass), and although the track’s unprecedented drum part was not programmed by Prince (the beat was originally programmed into a Linn LM-1 drum machine by David Garibaldi for Roger Linn, although it is unknown how Prince became owner of the instrument), he still formatted the part to where it fit in the song, creating a drum part that drummers still have a hard time replicating almost 35 years later."
I fell down a YouTube hole looking at instruction/re-creation videos for some of my favorite Prince drum patterns and came across a comment where Jesse was quoted as above. This didn't come up. Thanks for pointing me to it.
