I would also suggest at least one dedicated quantizer. The Disting can do it. But I would definitely NOT recommend the Disting in a live set-up unless you can set it up before your set begins.

It seems that the Klavis twin waves can output it signal pitch quantized which deals with biggest part of my problem. And as you pointed out I can use the Disting's quantizer in case I need it.
