Like other Eurorack Oscilloscopes, QUADSCOPE does not include an anti-aliasing filter at longer timebases (ie large time/div settings).

Preventing aliasing is easy with QUADSCOPE. Simply turn the right knob fully clockwise and then turn it counter-clockwise until you see your signal. This will be the correct representation of the waveform. If you continue to turn the right knob counter-clockwise you might see aliased versions of the input signal.
