Polyphonic modulation/Multitrack Sounds

Hey guys and girls!

I just recently became an A4 user and I’m so far very pleased. But I have a lot to learn and here’s a few questions:

I’m wondering about polyphonic sounds and how they work. Can i for instance have different filtersettings for different voices? And can I use more than 2 EGs and LFOs to modulate the sound?

And I’m also wondering if there’s a simple way to save a sound that is created with several tracks using the neighbour-function? Or do I have to save the sounds in parts?
