I was using two R-Mix's in one effects bin and both went blank.
 
Has anyone else tried using two instances of R-Mix in one effects bin to achieve a special effect and found they have gone blank?.

I have seen a thread about the R-Mix screen going blank. 2 instances in one fx bin is a first (for me). Just for fun, I dropped two instances of R-Mix in a test project both in a regular track and then in a buss. Let the project loop for sometime, changing R-Mix params in both instances. They did not blank out. Still you should log a bug report. Probably not many have tried the dueling R-Mix thing.
