Beginners friendly detuned snappy dark bass, drone and plug at once by Phobik
For some too simple and stupid, but I think for some others a good starting point for darkish sounds, not just the bass like you hear in the preview. There is a simple Chorus and Reverb added. Preview is not perfect, you will get better results easily.
Playing with Filter and LFO / Mod Depth makes fun as usual. Env1 Decay on 2 o`clock takes out the snappy start and smooths it.
Important to get the detuning "right", try to look via spectrum to add the overtones between.
