This trance/house bass

[TW1306]

I've heard slight variations of it in various tracks, here's a few examples of the general sound I'd like to get:
(0:14) ^
(2:47) ^
(1:27) ^
(from start)

Any tips would be greatly appreciated!

tried in Vital.
Maybe it can get you in the ballpark
Messing around with 3 sines. Skip to end, where the sound is more dialed in.
Tweak to fit better

osc1 = main sine
osc2 = plucky sine
osc3 = sub sine

The typical organ bass of the nineties? Korg M1 is the first thing that comes to my mind....

A similar (classic 90's) organ type of sound is also possible with the Juno-106 (emulation)....

Stacking sine waves is not a bad idea in principal, but in my experience this type of sound works better with chords.

A monophonic organ bass needs a little more harmonics....

You can use a sine wave with harmonics that resemble a fifth chord. Then adjust the filters to make it more plucky.
I have created several of these types in ableton wavetable.
