Primarily a voltage controlled bass drum. Really it’s a VCO, VCA, and EG all in one. As a bass drum it will have the house pumping. Also does fart noises and high pitched stuff. Put a LFO into the CV and get some psychedelic thumps going on – or whatever.

The voice/oscillator is a sine-enough-for-rocknroll shape, and turning the HARMONICS knob gradually morphs the sine into a square wave. The CV input is 1V/oct with OK tracking; this thing doubles as a sine/square VCO.

The attack/decay envelope has a dedicated output and is great to chain into a VCF (or maybe a VCA controlling white noise).

SLOPE AMOUNT controls the amount of EG that goes to the VCO pitch. To get that thumping 909ish type drum sound the initial “hit” has a higher frequency than the end decay. The slope amount controls how much higher in pitch the “hit” is. This ranges from no slope, to subtle slope, to laser sounds.

The input is activated by pretty much any hard edged wavefore – gate, trigger, square LFO.

BouncyReview by Mr. L
Not bad. A round bass drum, I had hoped it would have a bit more punch to it. Fairly easy build, be aware of component size when ordering parts. Good kick in the rack. (Posted on 9/28/2017)
Drum MayhemReview by Mr. Mojo Risin'
A versatile drum generator, VCO, VCA, and EG. Although you won't find any documentation about the trimmer, be sure to adjust it before using the module. You can get some super LOW LOW LOW bass drum sounds out of it (The trimmer is used to set the initial frequency). I really like the circuit board design of this build. It's not crowded which makes soldering components quite easy. Compared to other loose-fitting, multi-level circuit board designs, the header pins located at the top and bottom on this one ensures a snug fit which won't pop loose. With the exception of one polystyrene capacitor and the 3.5mm jacks, the BOM contains a detailed SKU list of easy to find and _inexpensive_ parts from Tayda. Not including the PCB/Panel, the cost for all parts was super low... less than $19 !!! NoiseReap doesn't make any more of these PCB/Panels so get it while you can. (Posted on 7/22/2017)
