FM AID

A 4 HP through-zero linear frequency modulation module, analog and free of digital aliasing: any signal as the Carrier and the Modulator, four shaped outputs.

Key features

• Through-zero linear FM (technically phase modulation), any signal as Carrier and Modulator
• A sawtooth Carrier gives sine, triangle, sawtooth and square on the four outputs
• FM knob for the modulation index, bipolar CV knob and CV input for its depth
• The Carrier normalled to the Modulator's input: one source alone gives wave folding sounds
• An onboard trimmer for Carrier levels from 1 to 12 V
