Loop to fast to process?

Hi Nic, everyone.

I have a script that produces problems and i managed to break it down to this loop.
After several ok runs the first counter L5 which is compared to G1 just doesn’t count up correctly
In the Labels should always be displayed 9 (left) and 8 (right)

After sometime the left label drops town to some unpredictable counts like 4, 1, 0 or something else.
Letting it run longer completely freezes StreamByter - the host stays responsive (Tested in AUM and AudioBus)

I cant figure out where the problem is.
Is this running to fast? Am i doing buffer overflows?

It would be really great if you could have a look through this.
Thanks in advance.


Principle:
Loop should run G1 times
Inside loop should generate random number not identical to the last one
If true store random number and raise counters for main loop.

Quickest error viewing possibility is when running on high bpm (like 250) with any note-feed. I used StepPolyArp Unit to feed permanent notes.


#problematic loop

IF LOAD

 ASS G1 = 8 #
 ASS G9 = 7 #
 ASS L7 = 0 #

END

ASS L6 = 40 #
ASS L5 = 0 #

IF L5 <= G1 +L

 ASS L3 = RG9 # random value 0-G9

 # check if identical to last value
 IF L3 != L7

   ASS L7 = L3

   # if not identical raise counters
   MAT L6 = L6 + 1 #
   MAT L5 = L5 + 1 #

 END

 SET LB0 L5
 SET LB1 G1

END
