Alan braxe playing autorepeat with SP 1200 - possible?

Didn’t watch the video yet, but it sounds like this is what you’re asking for maybe?

Beat repeat timing with fader or pads

The shortcut is: hold Quantize key while turning encoder or pressing arrow keys. That changes the default quantization, so it will affect any pad whose quantization is set to default. I get that is not exactly what the OP is asking for, as it would require three hands to change the quantization while also pressing the pad.
