Reproducable:
for example:
Working with the seq of Spark (VST), watching e.g. velocity, decay, etc. of single tracks - changing the pattern to another pattern - e.g. velocity parameters keep the same (BUT only graphically!!!) - clicking again to e.g. velocity, every is fine again (graphically spoken!).
sound is changing with pattern change!
(SORRY FOR MY POSTS...

i hope this is ok for you, because it seems, i'm the only one posting bugs and feature requests at the moment, but i want a mega Spark in my studio in the near future...)
