FYI, I’ve been playing around with clipper and saturation plug-ins lately and it appears for those looking for a stock hard clipper for Cubase (Pro), all you need to do is set the included SoftClipper harmonic controls to 0%.
Screen shots attached are for a snare hit, comparing original (rendered) drum loop, SoftClipper with 50% harmonics, SoftClipper with 0% harmonics, and for variety, the free KClip Zero plug-in.
All plug-ins have 3.9db input applied. (KClip output a little lower due to oversampling? Regardless, check out the peaks.)
Original track:
SoftClipper with 50% harmonics:
SoftClipper with 0% harmonics:
KClip 0:
Of course this lack of level-matching means SoftClipper is NOT the plugin to use for clipping. Sorry for offering false hope of a stock clipper plugin within Cubase.
