Here's a fun little patch. It's partly inspired by the band Papadosio, who play a lot of solos on analog synths where they vary the rate of a square or sawtooth LFO up and down throughout the solo.

Use the mod wheel to control the repeat rate.
Tap the sustain pedal to briefly disable the repeat effect.

The next step is the famous Lowrey Organ "Marimba Repeat" feature used in Baba O'Riley.

The notes B,C,C#,F,F#, and G repeat on the "on" 16th note, while D,D#,E,G#,A, and A# repeat on the "off" 16th. So, given a note number from the keyboard, how do you get its pitch class? This is the "modulo division" column: you use a note quantizer to round it down, and then subtract the rounded-down value from the original value. Normally you'd set the quantizer to 12 notes, but here we can use 6. Apply some offsets before and after the division (for reasons I can't quite explain), then multiply the result by 4 so that it can be used to control a sequencer.

The repeat circuit here is a lot like the Wheel Repeat circuit, but an 8-counter (shorted to make a "2-counter") distinguishes the "on-beat" pulse from the "off-beat" pulse.

I didn't put a lot of thought into the organ sound here. It's just one I had handy. The EQ in the effects section has a lot to do with the final sound; it's inspired by someone else's patch from the internet.

For Baba O'Riley, choose variation 1 and set the global clock to 238 BPM.
