Hi, i recently started reading Designing Sound by Farnell and im in chapter 17 about additive synthesis. Seems like the abstractions called [spartial] and [partial] are not included in my library. Im running pd extended 0.42.5 in windows 7.

Are these real abstractions? or are they just there to explain the concept. If these abstractions exist could somebody point me in the right direction to download them? Id really apreciatte it.
Thanks in advance.
