It's just a question of filters, the more channels you want, the more filters you need, and the narrower they need to be. Twenty channels seems rather excessive?, are you trying to build an audio spectrum analyser?.
I thought that each channel could hold about 4 strings of lights that is 16 strings I was going to use something like 80 strings plus a couple of trees. Is there a program on the PC that you can use to customize it and plug into your pc?

Channels can power a certain amount of watts, and certainly a 3 or 4 channel light unit should probably be able to power more than a USA outlet can provide. You need to check the consumption of your lights.
