I love the idea of TKOG's glitch pedal, but it's out of stock more often than the Axoloti core... 
I looked around and couldn't find exactly what I was after on the forum, so here it is. I'm sure it could benefit from some refinement and better labeling.

This pedal is a granulator that emphasizes the random grains as a core feature. I'm not too familiar with the looper object you're using but I think the main thing you want for this patch instead is to scan through the wavetable's 'position', which is how the glitch pedal kind of 'skips' backwards.
Look into Johannes' grain series of objects. Specifically jt/graintable. Right click the gray bar at the top of the object and head to the help patch to reverse engineer it a little bit. The other objects have cool grain effects too, and are worth checking out.
For the thrsh mode look into rbrt/ctrl/threshold and play around with it a little. It's adjustable too which is a cool feature that looks like the pedal doesn't have 
Almost forgot a favorite community patch found in the library: cpwitz/effects/grains/grain-mill
This patch may interest you - was going for the mini glitch/revolver sound. I think this one currently syncs with a midi-clock but when I have some time over the weekend I can post the version that runs on a tap tempo that you could easily switch to just a fader to work more like the size option on the mini glitch. I'll give your patch a try when I get a chance
This was my first attempt as well - https://sebiik.github.io/community.axoloti.com.backup/t/wip-stutter-glitch-effect/5865
Came out more like a CBA Mood though and was never really satisfied with it
After watching Joel Rich's interpretation of the Greenwood Max/MSP patch, I took another bite at the apple and ended up with something much more musical.
I believe that this is close to the functionality of Joel's and (and possibly closer to the original). Needs a bypass toggle, tempo light, clearer comments, and some other quality of life features... but I'm happy with it so far.

Worked up a version of my patch to trigger from the envelope - also can control pitch/speed of the playback separately (can control together with the "lock s-2-p" toggle. Uses @MattilynMattroe object to quantize to intervals so it stays in tune with your playing when you change pitch. Can tap in the tempo to set loop length though with it running from envelope it doesn't really matter as much. Envelope trigger could probably use some tweaking, I just grabbed one I was using in another patch.
