A quick search didn't help me - in the RBN documentation, they state the following, with C3's note.
There are two kinds of drum rolls for both Pro and standard RB Drum Modes.
- Standard Drum Rolls are authored on note 126 (F#8). They work similar to fills where you start the roll lane where the first note is authored, and you end the roll lane so it doesn’t overlap the last note in the roll.
- Special Drum Rolls are authored on note 127 (G8). They are used for cymbal swells and allow the player to do a roll that is divided between two pads. It is authored the same way as normal rolls, but should only be used for special instances. A good example would the cymbal swells at the beginning and the end of The Beast and the Harlot.
- C3 note: Many people have found these two note rolls to be unfairly strict and hard to combo, so consider charting cymbal swells as a one lane swell (usually on Green cymbal).
I'm charting a song that has several cymbal swells. I'm still a little uncertain how to do it based on this. Should I still be using note 127 BUT just charting note hits on one lane (green)? Or are you recommending using note 126 because 127 only works with the two-pad method (which is jank and to be avoided)?
What I initially did was use note 126... then authored 16th notes on the green pad. But then even on easy difficulty it gave me something much more like a drum roll and showed a bunch of missed notes as a result. Clearly wrong. How ought I be doing this?
