I agree with the above, that doesn't wound bad or fake. Part of it could be that you know it's a fake, a synth, so you'll always hear it as such. Same with other people who've used or heard a particular synth version, they know from working with it it's fake so no matter how well it's done it will always sound fake to them.
I LOVE this kind of stuff, this is exactly what I want. Please do more as you mentioned.
I've found some things in the same vein online, they inspire me to write some interesting melodies, at least to myself.
