the first sample is just a vocal, guitar and a string pad.

the second one is also just a pad (stringish with the filter cutoff quite low)

basics of a string pad:

2 saw wave oscillators. (if you got a sub oscillator, like vanguard, set that to saw too.)

tune the oscillators an octave apart.

on the amp envelope, set the attack time fairly long, the decay time fairly long (or max out the sustain instead), up the release so that it lingers after you release the note.

on the LFO, set the first available LFO to positively modulate the tuning of oscillator 1 (this will make its pitch waver). set the LFO rate for this oscillator fairly slow (so the waver is more like an undulation. remember how much you detune the LFO.

on the second available LFO, negatively modulate the tuning of oscillator 2. basically detune it like you did oscillator 1 only do it the opposite way. also set the LFO rate fairly slow.

adjust the filter envelope to taste. (if you learn subtractive synthesis i can give much more complex details on this section and recursive modulation to simulate real string sounds. but im just learning this myself so ill leave it out for now)

close the filter cutoff nearly all the way on low pass (4 pole if its available - this is sometimes called 24dB low pass). up the resonance a tiny bit. and detune the oscillators until it starts to have this lovely harmonic kind of quality. dont detune too much or it'll sound out of tune.

you can do this on pretty much any synth that is capable of producing a saw wave, detune and has an LFO.

although the timbre and texture and overall quality of the sound depends on the sound of the saw wave oscillator and the modulation capabilities of the synth.
