Another cottage-made, voltage-controlled addition to the VauxFlores family, we introduce the Pautron. Directly descended from Number 44, the Pautron combines the lo-fi chirps and crunches of a 4093-based cascading square-wave synth with a quick-and-dirty four-channel sequencer with two outputs – one providing a standard, stand-alone audio output and the other offering up a Control Voltage output that combines the voltage of each step with the chirps, glitches and wobbles of the synth section. The result – some relatively chaotic sounds and CV blasts from a moderately small footprint – not to mention a reasonable price-tag.

Oh, right, the name. Yeah, it’s named after my amazing wife Paulina Velazquez-Solis. She did the artwork for them and had a fairly large say in the design of the circuit – I mean, considering it’s kind of named after her, you would hope she would. Anyways, enjoy – feedback, etc – always welcome.

Pautron 1 in spring green – currently for sale at Control in Brooklyn, NY.

Pautron 2 in Lavender. This one sports a 4015 shift register in place of a sequencer – slightly different sound – more random and chaotic. Does wonders while tweaking control voltage. At the moment, she be available via the good folks at RobotSpeak in San Francisco, Ca.

Pautron the 3rd in blue. I changed up the layout a bit and streamlined the design, but it’s more or less the same core. This one now lives in Oakland, Ca.

Pautron 3.2 in black, gold and blue. This one sports an actual printed circuit board instead of the usual perfboard and point-to-point. Progress! Currently at large in Evergreen, Colorado.

Pautron 3.3, designed in anticipation of our 2015 TicoTronics workshop in Costa Rica.

Pautron 3.4. largely similar to 3.3, but eh, let’s categorize any and all for posterity.

3.5 – made in the dregs of a blizzard out of stuff mostly lying around the workshop.

3.6 – this one’s from the batch we did in Takoma Park in 2016. The circuit is tweaked a little, but the functions are largely the same.

A couple quick videos of the Pautrons in action. More on the way as we flush out the gallery.
