The implementation is pretty great too.
There’s even a tool to automatically randomize the size of the slices.

This opens up a whole new world of musical possibilities.
It’s both daunting and exciting.
But not everybody is happy.

Technically, Abletons new machine is superb.
You really can dial in anything you want.
But it ignores a large part of what makes microtuning interesting: the cultural aspect.
And this aspect is missing from Microtuner.
On the other hand, if you strive to be culturally inclusive, then you risk leaving people out.
