Ed Hetzler's fiddle fakebook online has a simple little utility there you can use to slow down his MIDI's. And MidiNotate lets you determine what speed you want to go, how many reps, whether to start practice at one speed and speed up as reps go along, and so forth.

Another tecnique is to play only the accented notes of each measure to get the skeleton of the tune in your head till you have that securely enough to start filling in the ornamentatons in between the accents.

Let us know if you want more info on either of those, here or by PM if we miss it. Hardi is self taught and he may have some other ideas.
