I've recently fallen back in love with this Orb tune from the late nineties and am pondering what they used for that squiggly little ARP line and how I could set about making something similar myself...

Could someone help me recreate the synth that starts playing around 0:11 of Soda stereo unplugged version of 'Cuando pase el temblor'? to me it sounds like a mouth harp or something like that. im not sure if the player holds the key down using an arpeggiator or if he plays all the notes. Any advice?

This subreddit was recommended by someone from r/musicians. Need help replicating the synths and pad sounds on my keyboard (Yamaha PSR SX 720). I don't want it to be plugged into my laptop as a Midi Source. Just want raw voices from the keyboard itself if anyone knows about it. Thanks.
