The Algo is an elegant, complex oscillator bank of four sound sources configurable into multiple algorithms of FM timbres, and it’s a beautiful cluster of additive sine waves that are eager to fold and warp.
These Catalyst modules are based upon the Emblematic Systems module of the same name. However, 4MS have turned it into two modules: a controller, like the original, and a sequencer.
Effects, particularly spatial effects, constitute a relatively modern facet of modular synthesis, but this need not mean they should only be used as enhancement for existing sounds created on other modules.
