Usine free VSTi can do that, even for live ,pick midi in, apply QT, reouput midi out.

can even do that as osc as im actually trying, ie a swich is quantified to contol any live device, with no midi assigment needed.
it can do much more in standalone, it's a true live oriented software, as expamle this basic feature you expect on a live software is avaible for every interface item, can be "quantize",set max/min, be in absolute, relative, ect, automation live sampled/replayed ect..
in fact every things live miss that make you think well, should'nt "live" be called "extented sequencer", as there are far more live oriented software, usine being the best ive ever seen.
mmmm would not have same commercial success maybe..
live is a great software, i love it and use it from v3, butfor me it's no more the best
"true live" software. It's a big compagny mix of features between asked conveniant daw features and cleanest/easiest/clever workflow ever made fore sure, still a true live oriented softare need to match the live performes demand, and this can only be accomplish by a modular approach imo.
live have filled their lack with picking Max for live, this is an intelligent solution as max is really the best candidate for that, and live will remained "user friendly".
what is cool with usine is that's all with one soft only, from building your custom racks, custmoizig your controls and runn them full screen with ie multitouch screen, right of the box, and it's cost a fraction of what cost ie live+max4live+lemur+mu=$$$$, usine free+wiimote = 0, while doing better imo for "true live performance", even for free!!
(im not speaking about extended djing or cueing presequensed liveset, but live performance, might the limit being hard to describe nowadays... )
