Lower latency of retune~? Push 3 Autotune solution

Hi there,

Apologies if any of this is basic knowledge, I'm still a relative newcomer to Max/MSP after being introduced to it in a college class last semester. I've been searching for a low (sub 10ms, sub 5ms if possible) latency autotune solution that could be implemented on Push 3 Standalone for live performance—which means I can't use externals or the vst~ object either. All of the solutions online I've found so far use retune~ under the hood, but unfortunately whenever I test the latency of this object it's always at least around 50 milliseconds. Is there any way to lower the latency of retune~ to make it more functional for live performance? Or is there another object anyone would recommend I use instead?

Thanks so much!

Ben
