Each Amiga is capable of playing four independent waveforms. The HMSL Shape Editor is
used by Lottery performers to select any of these waveforms, and design its harmonic
spectrum up to 127 partials. In this figure, the performer has chosen to raise the magnitude of
a few lower partials, and to raise the magnitude of a wide range of high partials.
