It also needed to include all the major functions of a modular synthesiser including oscillators, noise-generators, filters, ring-modulators, but an intermodulation facility was viewed as the primary requirement; to enable complex synthesis processes such as frequency modulation, amplitude modulation, and modulation via an external source.
Det var også nødvendigt at medtage alle de vigtigste funktioner hos en modulopbygget synthesizer herunder oscillatorer, støj-generatorer, filtre, ringmodulatorer, men en intermodulation-facilitet blev betragtet som det primære krav for at muliggøre komplekse synteseprocesser såsom frekvensmodulation, amplitudemodulation, og modulation via en ekstern kilde.
