Full featured kick drum
The DoublePlusBass is a kick drum inspired by Thomas Henry's Bass+, with more control over all the parameters of the kick sound. Standout features include a possible 1V/oct tuning, a waveshaper that moves from a triangle wave to a clean sine, to a buzzy folded square wave, the possibility to use a sagging 808-style kick pitch envelope or a stabby 909-style spike pitch envelope. There's an envelope out jack that outputs a voltage designed to sidechain (or "duck") other signals. The EnvOut output sits at about 10V all the time, dropping down to 0V when the kick is being triggered, so can be used with VCAs to create room for the kick drum in your bass-heavy mix.
"Eleven knobs for a kick drum?" they will ask, "Preposterous!" but they will stop saying that when you turn up the volume.
