Setonix Synth Marsupial - DIY Build

Following up our last build of the Setonix Synth Boing!, we decided it was time for another back to back build of their Setonix Synth’s newest module, Marsupial. What is it you ask? 

The Marsupial is a dual VCF module that is based around the re-issued AS3350 filter IC. Due to its normalization between the control inputs and the parallel switch, the Setonix Synth Marsupial is a unique filter that can surprise any artist when patching it up. With that being said, let’s jump into the build.

Let's Get This Build Going..

Starting off with the build of this module, we will work on the backside of the PCB first. You will want to solder the 2×5-pin power header, 3-pin Series selection header, and two 25k multi-turn trimmers.

Be careful not to hold the iron on the parts for that long as you can release or damage some of the pre-soldered SMD components.

Don’t forget to place the plastic shunt over two of the three pins of the 3-pin header–”BP” will normalize Filter A’s Bandpass output to the Series switch, while “LP” will normalize Filter A’s Lowpass output to the same.

Setonix Synth Boing! - DIY Build

As many modular manufacturers come and go, we often are intrigued by the not so well known ones. Setonix Synth is one of these, and we have to say that they are coming onto the scene with a HUGE BOING! Located in upstate New York and started in 2021, Setonix Synth derives its name from a little cute marsupial from Western Australia. (thats pretty rad). 

We happened to be surfing ETSY one evening and came across the Setonix Synth Boing! by chance. It was a partial DIY kit and it was very reasonable priced. We ordered it up and waited for it to arrive. Upon its arrival, we knew it would be a fast build due to the SMD components being all tacked down. 

Setonix Synth Boing! - What is it?

The Setonix Synth Boing! is a discrete transistor based low pass gate with some grit. It is a light dependent circuit that uses vactrols and a JFET transistor input and output stages. The Boing also uses an active LED control circuit, thus allowing for negative feedback and some gnarly overdrive…. basically, its a kick ass 4hp module that everyone needs in their rack.
