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 boom 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. Inserng a cable into the FOLD jack will break this normalized con-
necon 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 acon 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 posion of the FOLD knob and by the level
of the FOLD CV input. At low levels the FOLD controls acts like a simple amplier. When the FOLD amount is
zero the output will also be zero. As the FOLD level increases the amplitude of the output will increase unl the
maximum output level is reached at which point the folding will begin to take eect. The gure below shows
the eect of the wave folder on a triangle wave for various sengs of the FOLD control.
