WAVE FOLDER
The SHAPESHIFTER module includes a fully analog wave folding circuit. This circuit is the same that is used on
the intellijel mFold II module . Its input comes from the FOLD jack on the bottom row of the front panel. This jack
is normalled to the OUT 1 jack meaning that when there is no cable plugged into the FOLD jack, the signal at
OUT 1 is fed into the wave folder’s input. Inserting a cable into the FOLD jack will break this normalized con-
nection and the wave folder input will be taken from whatever is connected to the cable. This allows an exter-
nal signal to be acted on by the wave folder.
The action of the wave folder circuit is to bend or fold the input waveform back on itself. This generates har-
monics brightening the sound. The amount of folding is set by the position of the FOLD knob and by the level
of the FOLD CV input. At low levels the FOLD controls acts like a simple amplifier. When the FOLD amount is
zero the output will also be zero. As the FOLD level increases the amplitude of the output will increase until the
maximum output level is reached at which point the folding will begin to take effect. The figure below shows
the effect of the wave folder on a triangle wave for various settings of the FOLD control.
