> Quantization is a net improvement. It takes unlistenable performances and makes them listenable.
It also gives musicians a false sense of skill if the producer just gives thumbs up and all they hear back is their own quantized drums. Instead of, you know, practicing and actually nailing the beat.
If all you do is quantize it to the grid, why even bother setting up a drumkit to record. We all know those hits are being sample replaced anyway, might as well just pull up the midi kit.
