• The Witch mode is based on a four-tap delay, whose delay times are set by the spread
control and modulated by a quadrature oscillator. The four taps are then sequentially
crossfaded between by a synced sawtooth oscillator, windowed and sent to the feed­
back and output circuits. In a way this Mode resembles a faulty pitch-shifter design.
Yumm.
• Zombie mode is also built on a four-tap delay, but the delay times are not spread out
and the taps are not faded between.
• Demon mode is a little more complex. Here we have a quad synced quadrature oscilla­
tor that modulates delay times of four four-tap delays. For example, the four delay
times of the first four-tap delay might be modulated by four 10 Hz sine waves at 90
degrees phase shift relative to eachother while the delay times of the other three de­
lays would be modulated at 20 Hz, 40 Hz and 80 Hz, respectively. Additionally, the
outputs of the four delays are level-scaled and panned using look-up tables. Sounds
cool, huh. Yeah, it does, actually.
