I've been trying to design a synth with the characters of the synth that occurs right at the beginning of this song. I get close, but there's something missing and I'm not sure what it is. I know that the are doing some post-processing to get the tape stop effect, I don't really care about that aspect since I need to use this synth in a live context.
Method 1: I've tried using a couple of sawtooth waves where they are slightly detuned (like a super saw).
Method 2: I modified a Hoover Bass in Logic Pro X, which is basically 2 Sawtooth and 1 rectangle/pulse wave.
