This sounds so much better! Can you teach people how to use $FB because most of us have no idea how that command works lol
As far I've learned looking into the AMK readme, it basically works like that:
[How many notes you want for the arpeggio (Use 00 to turn it off, 01 basically could work as well, then just zero all the other values)]
[Lenght/Duration for all of the notes, in hex (it helps a lot looking into the AMK readme)]
[All of the note values]
The last one is the most confusing one, cause you'd need to add and subtract from the VERY FIRST note.
Increasing notes will be positive (00, 01, 02...), while decreasing notes will be negative (FF, FE, FD...), in hex.
So by example, a simple major chord will look like this: $FB $03 $06 $00 $05 $07
(I may be wrong on something, so anyone feel free to correct me if am I.)
