i have a HUGE interest in that also
It involves creating a "Layer" channel and assigning each note in the keyroll at the bottom to a sampler channel. It's a pain in the ass.
Copy and pasted from a forum where I explained it a few years ago...

I haven't used it in a while, but it's sort of tricky. The way you have to do it is as follows:
Export the GP4 score as a MIDI file. Open Fruityloops, start a new blank session and go File>Import>MIDI File. Import all the tracks or just the drums, doesn't matter.
Right click on the channel that the MIDI Drums are in and select Piano Roll. Choose the selection tool and highlight all the notes in the MIDI track and hit Ctrl+C to copy. Now open gp4template.flp and right click on the "Layer" channel and select Piano Roll. Paste in all the MIDI data from the other session with Ctrl+V.
That should be the end of it and it should work fine, any problems let me know.
EDIT: Forgot to mention this but it's REALLY important. In the template, make sure you go through all the other channels labelled kikbig, snrambient, etc. and load in all of your own samples, because otherwise it's trying to play samples from MY computer and it won't work haha...The way the Layer works is that you assign each key in the layer to a different sample and it triggers all of those different channels, just like how you would program drums using a piano roll in a MIDI sequencer. Took me AGES to figure that out but I'm glad I did...very handy for programming an entire song in one pattern and copying/pasting stuff with ease...
