I found out Chance Command sometimes doesn’t work with ‘certain’ commands on steps.
1.Put a note, and set reverse sample FX command onto few steps after into FX1 slot.
2.Put a Chance Command FX onto FX2 slot
3.it’s not working.
p.s : OFF! command seems to work, but the other commands are also sometimes work and not.
Always
Hi @djbowlcutkr , thanks for another successful bug hunt 
This one looks a bit trickier and less straightforward. However, I must admit there are some inconsistencies in how the system interprets the “reverse” function. Therefore, I will log this internally for further review. As mentioned in your previous bug report, we will inform you as soon as we have any clarification.
There is a workaround for this issue, though. When you want the “reverse” function to work with the “chance” parameter, make sure to use all the other step parameters (don’t leave them blank).
If you want to play the same note (like in your video), just copy the whole step, set “reverse” to FX1, and set your “chance” value to FX2. Hope that helps
thank you! but at the moment, I use granular or long 1 shot sample and making it tweaks during it plays in sustain for making it seaminglessly automated, So would be nice to fix this issue
