I'm using a generic midi cable that works/plays fine with my monome stuff. I never (that I can tell) lose power connection as the 4character display stays as what it was. If I unplug and replug it goes to scrolling "SOFT STEP".
I can try a different cable into the only other USB port on my laptop.
I'm not using the SS cooking, so there isn't a reset command. I did try to bang the loadbang inside the jk.stepcore, but that doesn't do anything other than on patch load.
Quitting the patch and reopening didn't seem to work, I needed to quit Max. I need to test this more thoroughly as I've only noticed it happening twice, the first time I had to quit Max, the second time, I stopped programming for the day.
It's a shame I worked out a nice 'page' system where I can scroll through different pages, and it will store/clear LED states as I switch around. For you monome guys, I managed to get some MLR-style scrolling/retriggering/looping stuff going, which is quite awesome for a foot controller.
