Sure.
This is a 4 bit shift register using the trigger outputs as memory. Input 1 is the clock and input 2 is data. The value of input 2 only matters at each clock tick on input 1, otherwise it’s ignored (the second script in the scene should have been script 3, not 2).
Each time a clock is received, the values of the triggers “rotate” from 3 to 4, 2 to 3, 1 to 2. The old value of trigger 4 moves to trigger 1, but if there’s a high signal at input 2, it’s inverted by the XOR operator ^.
(If you never send anything to input 2, it will never have anything to rotate since all the triggers will be off.)
So this way, if you keep clocking it without sending anything to input 2, the bits keep rotating in an unchanging 4-step cycle. If you keep input 2 high the entire time, it still keeps rotating, but alternating sets of 4 are the inverse of each other. The fun happens when input 2 is gated at a different frequency from input 1, giving you long but eventually repeating patterns.
The other part of the scene takes these four bits and converts them to a CV – assigning them voltage values that give nice harmonic combinations for pitch (inspired by the “Binary Counter” applet in Hemisphere Suite). It could have used note numbers instead of volts. If each step contributed the same value, the pitch wouldn’t change as the pattern rotates, only changing when a bit is toggled.
