Different pattern lenghts?


Hi all , today my fluxus froze several times. The lenght of all channels was from step 1 - step 60 , then i tried to change it on only one channel to step 30 - 60 . Anytime i tried this, fluxus totally froze and i had to make a restart. I tried the same thing several times and it happened again and again.
Does anyone experienced the same or a similar problem ?
For the rest i am still very happy with it :smile:
