I love experimenting with analog sound synthesis, I even have a Korg R3 wavetable synth that I can tweak my own sounds out of

Making a resonant kickdrum, a killer bassline, a noisy lead out of a simple sinewave -> best thing ever
I've never used Logic, so I don't know what it's native plugins can do, but if they have basic squarewave oscillators and a few base effects, I guess it can be done in a few seconds.
