PeRColate is an open-source distribution of a variety of synthesis and signal processing algorithms for Max, MSP, and Nato. It is centered around a (partial) port of the Synthesis Toolkit (STK) by Perry Cook (Princeton) and Gary Scavone (Stanford CCRMA). Like the STK, it provides a fairly easy to use library of synthesis and signal processing functions (in C) that can be wired together to create conventional and unusual instruments. Also like the STK, it includes a variety of precompiled synthesis objects, including physical modeling, modal, and PhISM class instruments; the code for these instruments can serve as foundations for creating new instruments (one example, the blotar, is included) and can be used to teach elementary and advanced synthesis techniques. Given it's STK heritage and educational function, PeRColate is largely un-optimized, though all the objects run on a 80MHz 7100, which is pretty good. PeRColate also includes a number of objects not from the STK; some are from RTcmix and others are our own evil creations, designed to crash your computer, but only after making some kind of interesting sound or image. |
