Think about it.
You have 128 filters per drum program. And for example you have that drum program on 3 tracks(384 filters). How do you map that? Do you map it per program or per track...?
How many filters do you have and how do you control them with CCs? I believe one midi channel can have max 127 CCs.
Now imagine how many parameters 64 tracks can have(not just filters: lfo, modulations, envelopes and so on).
The way it's done in the old ones is they have option to configure CC to control Qlink, and that qlink you map to what you want to control by external controller. By default it's not enabled.
We are talking about midi controller controlling MPC params, not mpc controlling midi params on external midi gear. That works just fine and a lot of people confirmed it.
My guess is it will be something similar in the Live/X.
