!!!*: This patch will not sound the same on your system unless you download the nightly build version of Surge Rack available at: https://github.com/surge-synthesizer/surge-rack/releases/tag/Nightly
(or when surge rack release version is at 2.1 somewhere in the future.)
Two play-heads play a melody at slightly different tempi. The melodies will go out of phase to reach a new combined melody when the phases match again with one melody shifted one note ahead, at which point the play-heads stay in sync for a few measures.
The song has three sections: One with a 12 note melody, one with two 8 note melodies and one with a 4 note melody. Each section is played until their cycle has gone full circle and the melodies line up again.
