The sound you mean is some type of synthetically produce voice/choir sound, with some breath to it. Sounds like a simple Halo Pad preset to me. All GM keyboards have this kind of sound. Could be another type of preset, depending on the brand and serial number of the keyboard. Or a Halo Pad layered with a Choir. Just browse through the choir section of a GM keyboard, and youâEUTMll find something like it.
There are definitely no mandolin nor xylophone samples in this song. I donâEUTMt even know what frootza means by this. Probably the Bright Piano (in the left speaker), which is also a preset on even the cheapest MIDI keyboards.
ThereâEUTMs also a synth sequence, which sounds like a saw wave, distorted and with a phaser.
The base is also a saw wave, but more detuned, probably also distorted.
And of course the drums. Sounds like a very standard drum computer, (Roland TR-808?) with effects.
