X-town rhythms with Weird Metronome

The syncopated "honking" rhythms in the X-Town Interchange Rag are tricky. I'm looking at measures 39 and 40 for m1 and m2, and 79 and 80 for md and mc. I recommend the Weird Metronome as a tool to practice those rhythms.

The Weird metronome is free from http://www.weirdmetronome.com/

Here's how practice the rhythm in measures 39 and 40 (or 79 and 80):
Set voice 1 to "low wood block" or some other sound to delineate every beat.
Set voice 2 to "hand clap" to play the rhythm of your part.
Choose the "custom" radio button and enter 12(12)01210(12)01210(12)0 in the box.
Set the tempo to 300 or so.
Click on "play"
Listen to the rhythm or play along until you can't stand it any more
Save the setting for a future practice session.

Measures 37 and 38 (or 77 and 78) are similar. Just change the last (12) to 1.
