Made a VST3 that randomizes your synth patches - been getting some wild reese and bass textures out of it
I built a plugin called Synerator that hosts your soft synths and randomizes their parameters. You pick how much chaos you want (subtle tweaks to full random) and can filter by parameter category - so you can lock your oscillator and just randomize the filter and modulation, for example.
I've been loading up Serum and Diva and just smashing randomize looking for gnarly bass textures and it delivers. Some of the reeses and mid-range sounds that come out of randomizing everything at 100% are things I'd never stumble into manually. Tons of unusable noise too obviously, but that's the fun of it - you're hunting for the weird ones.
Also discovered that if you save a preset made in one synth and load it with a different synth open, it maps the same parameter values to completely different knobs. So a Serum preset applied to Diva gives you something totally unrelated. Accidental sound design gold.
$19 at scottbrio.com/synerator - Mac (Silicon/Intel) and Windows, video walk-through on my YouTube and product page. Built it because I wanted it to exist and figured other people would too.
