http://www.soundonsound.com/sos/jun06/articles/reasontech_0606.htmcool article here on using the redrum in reason
small tip from me,
if u click this small "Red light" above each button it toggles it on
this activates the "Flam" setting which changes its articulation.. partiticularly useful when programming percussion parts
you can hear this most if the flam dial is all the way applied (100%)
and the button next to the flam setting, this just makes it automatically apply flam to every step that u press,
regardless of this button to the right of the flam dial's settings, clicking the red light above the step will enable the flam for that particular step!
