Yeah, the connections to the 4066 should have diodes and a pulldown resistor. And I’m not sure what’s supposed to be going on with the +V connected to the output. If you don’t need s-trigger the 4066 could be replaced with a smaller LM358. Or just go directly to the output jack, the buffering isn’t necessarily mandatory.

> I try to make schem for an old school Baby 8 seq with a CD4017, with some mix of several schem, and i’m not sure that my mix holds the road . with some on/off/on switch you can on each step select, on/off cv & gate out or choose this step as reset step. i use this part of schem for the external clock in, but only the up part (not the gate to trigger one) and i don’t really know what doing with the pin 2 of opamp, in my schem i only connect it to 100k then +12V here’s my test on…
