Ok, now that is out of the way.
So i'm assuming your using a AKai mpd24. Those buttons are used to send commands to a remote control harddrive recording sysem. Most send a specialized messages via MMC or midi machine control. So 2.41 resolume is not going to understand that.
This is used when your producing music not when performing.
Can Jorvis confirm that Resolume 3/4 supports this? I didn't think it did, I never got those working in Res 3/4 but Oaktown has other experiences it seems. Maybe i just didn't enable the right functions.
