I have an older model m-audio Radium 49 MIDI keyboard. It seems in Reason my MIDI sliders and knobs have preassigned controllers set to them. When I go to switch them to another controller the old preset still sticks. Causing me to control 2 of reasons controllers through one of mine! I can't seem to delete the other 'randomly' assign controller from Reason and when I 'Clear MIDI mapping' option in Reason only my recently assigned controllers disappear.

I'd like to know how i can clear the memory on my MIDI keyboard as It's obvious the keyboard has presets I never assigned. I tried the 'Reset' option on the keyboard and that still isn't working.
Please help, this is beyond frustrating and negates the use of having midi sliders/ knobs on my keyboard.
