How to make these type of high synth lead tones

[Sausagefinger]

Hey guys,

First time poster. I'd really appreciate some guidance on how to create some of these high / high mid synth sounds like in these couple of tracks. I know it's probably simple but I just have no idea where to even start! I mostly use the NI Komplete package and prefer using Massive which I imagine should be able to create these sounds but any guidance towards other synths are welcome too!

The first synth sound heard in this Apparat song:

The first synth sound in this Kite String Tangle song:

Thanks in advance

Anyone able to shed some light?

The first one is a simple sine wave organ sound, going into a samplerate reducer and then a delay.

That actually makes a lot of sense - thanks for the reply. I'll give it a shot when I go home.

If anyone else has a different approach to get this sound as well please share away!
