Workout the bars of your sample. For example if it has drums playing a rhythm within the sample, chop them on the kick and snares. this will give you an idea of how to arrange the sampled pads onto your own drums also you could get rid of the kick and snare from your sample by adding attack to your chops.
Because I only check FP a handful of times a year I didn't see this until now. The reason Recycle was created is because this was hard to do in the early 90s when Recycle came out on hardware samplers. Recycle predates Reason and Reason didn't even get audio sampling until version 5. It didn't get audio tracks until version 6 unless you count the side DAW they made called Record which tied into Reason during Reason 5, but that was totally ditched again for Reason 6 or 6.5 I forget. Before that Recycle was the only way to get audio into Reason. Reason has come a long way. As someone who originally learned to make beats on Reason in version 2 seeing version 10 is culture shock.
