Ingo,
I'm impressed that CW actually have someone reading these things so I thought I might even get lucky and you'd read this too...
I've noticed quite a few different posts complaining about various manifestations of stuck notes. (I've listed a few detailed thoughts about when this tends to happen on the CW forum). It's a problem I have often, but it seems to depend on which device I load and how fast I play my mother keyboard.
Is there some obvious wisdom I'm missing, or is this a known bug? When I was demoing PulsarII to a friend they were impressed with all the functions and sounds, but kept asking why the notes were sticking....Of course I had no idea and could only "mash" the keyboard each time to stop the drones.
cheers,
Spirit
