How to Combine Midi Files...?

Hey there.



So I am trying to combine 2 different midi files.



Each file is a different tempo - but same time signature.



Here is the scenario:

Midi File 1 has multiple tracks, and set to 90 bpm

Midi File 2 has multiple tracks, and set to 102 bpm



I would like to use Midi File 1 as the base tempo for both files.



I would like to have the drum pattern from Midi File 1 run the length of both midi files and become the new drum pattern for Midi File 2



How can I accomplish this merger of files?



Thanks,



Sparky
