[L2Ork-dev] tabwrite crashes while writing a large audio array

[Ivica Ico Bukvic]

Thank you for the report. This is confirmed. I think it has to do with 
some kind of a vicious infinite loop in terms of redrawing (if you run 
pd-l2ork with -d 3 flag, you should see it in the console). Lemme 
investigate...
