I bought MPC Pro Pack and I'm trying to figure out how to use Anvanced CV tools with CV track. LFOs are straighforward but everything else seems a bit mystic for me, and the manual doesn't help very much.

I have two questions:
1) How does the Matrix works? The manual says only these words: "The Matrix section allows you to modulate different sources and sum or multiply them for complex signals." Nothing seems to happen although I choose the sources.
2) I thought I would use envelope-feature in my eurorack but the signal seems to be too weak and inaccurate. I set the depth 100 in routing and envelope but still seems to be weaker than basic EG module. I can use offset but then the voltage doesn't go back to zero. And the other problem: attack is a bit sluggish. Any tips?

Anyways I don't regret paying for it but I think I can't use it the way I planned. This happens all the time:)
