Ok, thanks, that sounds like a sane explanation. However it surprises me
a bit (maybe it shouldn't), since I read this in the "Launchpad
programmers reference" (pdf released by novation
http://d19ulaff0trnck.cloudfront.net/cdn/farfuture/zJMvGWWVN-T4_9ocxl0S-...):

"Hence a Launchpad MIDI message is always three bytes long. (For good
reasons, the driver does
not support running status.)"

Is there anyway to get a status byte to the driver/launchpad from my
code, so I don't have to rely on presses after opening a new batch of
chuck code? Could I for instance emulate "unplug" and "plug in" the
launchpad or it's driver from code?

I've been using the launcpad a bit with renoise, esp the duplex tool,
and somehow the launchpad works perfectly normal there, so something
tells me there is a way.
