Three independent Wave Multipliers that add intense harmonics to static waveforms. The primary multipler has voltage control over the amount of folding, waveform offset, and pulse width modulation. With two inputs, a huge array of sounds can be had. The Grinder adds "ringing" harmonics to any input, sometimes reminiscent to digital aliasing. The Lockhart folder is designed to warp a sine into harmonically rich waveforms. Think of these three Wave Multipliers as "anti-filters" dramatically adding harmonics rather than reducing them. Whilst the primary and Lockhart multipliers are designed for use with raw waveforms, the Grinder is particularily effective on complex inputs such as drum machines.
