Really classic house bass sound.
Classic bass sound
Great question, as this bass sound has gotten really popular of late particular in the Nu-Disco genre with cats like Tensnake.
Edit: i was wrong see phils answer 
Thanks for the tips, that is really helpful
It’s so annoying, the bass sounds so simple, but I still have a hard time emulating it.
Dont forget that theres a hefty amount of Glide or Portamento on those 303 basslines.
They also have “Ties” in the notes, which are like a longer note essentially.
Overlapping notes with Glide will give you a little bit of that sound.
its the lately bass patch off the Yamaha TX81z or also called Solid Bass of DX7
Are there any good vst plugins that can produce that kind of sound?
