Pad preset identification

I’m pretty sure I sampled this from a friend’s synth in the early 90s, but I can’t for the life of me remember which synth and what patch. Does anyone recognize this and maybe remembers where it came from?

80% sure it’s the M1, but I might be wrong.

I was thinking the same, but couldn’t find it on there. I’ll go through the presets once more.

There are a few M1 presets that come really close, but I can’t seem to find this exact sound.
