It's bascially FM synthesis using two sine waves and slowed right down. I then attached an LFO to a filter cutoff to make it sound more realistic.

Personally if someone played this to me and told me it was them scatching i would belive them.

Im going to remake the patch using reaktor at some point. The reason why is because i would like the modulation target to be an audio file instead of a sine wav. Although you can input audio into albino you can only use it as the modulation source not the target.

worth a pop anyway.
let me know what u rekon.
