Reply to Drum Racks and MIDI Clips

I used to use session controls (a.k.a., the APC Red Box) to move around the session view and launch clips MPC style from my controller. This sucked donkey balls for actual drumming, however, so I decided to use drum racks too. Now here's a problem: Ableton won't compile a python script with any double mapped buttons. So I comment out the red box stuff and go pure drum rack. No problem as far as samples/audio clips go, but the drum rack won't take midi clips, which is about 98% of what I have.

In short, I have a grid of 4 x 4 buttons I want to use for drumming AND clip launch of all types. Can anybody give me advice on how to get this done?
