Roland TR-8S Guide / How to ACCENT 

Well, there are multiple option to create a drum role. You could use the SUB Step or the Flam function to create some interesting rolls. However, the (main) roll is through INST PLAY. There are two ways, one way is hold down INST PLAY select the step 12 or 13 and then play one of the steps 1-11. Or within the INST PLAY mode hold down step 12 or 13 and then press one of the steps 1-11. I hope that helps :)

@@choppedstrandaudio4561 VERY HELPFUL, thank you!

Yes, the Accent applies to every single instrument. Unfortunately, it is not possible to have a different Accent for every single instrument. You can only apply it to your 16 steps. That is the reason why I normally don't apply it to my Kick. Substep and weak beat are much more user-friendly. Cheers

@@choppedstrandaudio4561 You can actually change a velocity per step & per instrument

How do you apply velocity change to one instrument and not per step? Thanks

@@choppedstrandaudio4561 By just selecting an instrument and doing the same thing. You can also press shift + step buttons and it will activate with half velocity

@@ladobarnovi221 Thank you, I knew about the half velocity already... I will give it a try.
