Astera Tube parameters

I just patched one Titan Tube with 8 channels and it somehow took up 480 parameters. Then I just wanted to see what would happen if I patched 16 of them and it only took up like 500-something. Why is this? I thought I would be good with 4,096 parameters, but anytime I add a new kind of light, the parameters used jumps up significantly

Thank you !!
