I am very new to Max and script programming, but i am failry certain that this is possible using Live's drum rack and Max.

I understand that Osculator can take OSC commands and turn them into MIDI which is then native to mapping in Live, but I think that Live doesn't support such easy midi mapping for Drum Rack, am I wrong? Can Max then take the MIDI can route it to the Drum Rack after Osculator? Or do I even need Osculator? Would it be easier to have Max read the native OSC commands?
If anyone could help me or guide me in the rit direction for being able to do this, it would be much appreciated.
Thanks!

I am having a problem assigning the midi values to the "pads" in the drum rack. I click MIDI, but it doesn't seem like it accepts any sort of midi input. (It doesn't blue out)
