Reaktor 6 Primary Sequencer

I set out to make a tutorial about making a simple sequencer in Reaktor 6 Primary, and got way too long-winded, so this first part is just about making a low-pass gate (LPG).

A low-pass gate is a low-pass filter that is functioning as a VCA. When it isn’t triggered, the filter’s cutoff frequency is subaudio, not letting any audio pass. When triggered, though, the cutoff frequency goes up, letting all frequencies through. In analog, too, this motion of the cutoff frequency is performed by vactrols, adding a quick attack and release that some compare to the sound of bongo.

In this video, I make a digital LPG, talking through the best numbers for an effective result.
