BRK Command on Tracks 7 and 8

[eddhy]

Hi there,

I'm having issues to repeat a 16 Step pattern on the sample tracks for more than 4 times. With BRK 0 command it repeats forever and BRK 01 until BRK 03 also work fine.

But values over BRK 03 seem to be ignored - in any case above BRK 03 the next pattern starts automatically after 4 repeats.
Can anyone disprove this with his NerdSeq on Firmware v1.23?

Probably it is only my wrongly adjusted settings... but which one? 

Thanks for your suggestions!
