Steel-drum type lead sound

Hi Phil,br
br
Can you give me some guidance on how to get this steel-drum type sound like the lead on this track, it’s most prominent in the track at about 4:16 onwards when the track drops:br

Not sure if it’s detuned sawtooths, or FM synthesis, or maybe a sample?br

sounds like 3 octaves of saws… maybe slight detune played as a chord. with some filter envelope
