Ah. Oh. Yes! Ooh! Maybe!
Dave Vondle from IDEO Labs posted a really cool add on for the arduino IDE that lets you retrieve the source for an arduino you physically have but don’t already have the source for. Essentially, if I understand this concept, I can tie the arduino mega inside each beatseqr to the source online, so that when you want to see how it works and want to change something on it, you can just plug it in, launch the arduino IDE with this add-on, and get the source from the internet. Sweet! I have asked a question about a minor detail, but overall the concept is really good, and I think I’m going to give it a try.
