I've been taking my students through the MSP tutorials of late, and as I was prepping for tomorrow's class, I returned to the scope~ tutorial. I've never worried too much about "scope crawl" -- as long as I could see the basic shape of the waveform, that was fine. Still, it seems to me that there's something weird about scope~. Maybe I'm just missing something.

The way I read the tutorial, help file, and reference manual, the two scopes in this patch should be interchangeable. However, on my system, after banging to apply the settings, the scope~ on the left exhibits no crawl, while the one on the right crawls noticeably.

Note I just realized I banged the scopes before saving, so the settings are already saved.

No, it will stop at 89 samples per buffer...

But to make a scope~ stop, its better to set the trigger mode to up (or 

down) anyway. Like you do with real scopes. I never understood why this 

isn't the default setting of scope.... Create a prototype of it...

Scope~ question (simple?)
