ducking with sidechain compression is a great way to clean up your track & make it more danceable. setting it up every time can be a pain for something so simple, though, & then you have to be careful to not make adjustments to your kick sound/pattern. even if you take the time to add a muted quarter note click to sidechain, you still can't freeze/flatten or easily incorporate it into a live set.
enter PUMP, a new max device from pATCHES. PUMP makes the 4-on-the-floor sidechain sound easy without compromising the control afforded by the standard compressor method. easily adjust the ramp with curve, offset, & length controls & simply dial in the amount of gain reduction you want to hear. PUMP is awesome for no-nonsense ducking effects live.
