Analog Lab.Swiss Dual Sub101A – DIY Build

Analog Lab.Swiss Dual Sub101A - DIY Build

Here at fiN Studios, we are continuously looking for new and exciting modules, synths or pedals to build. Not only do we utilize them in our own racks, we enjoy helping promote other artists or instrument designers. 

One of our most recent finds is the Analog-Lab.Swiss Sub 101A Duo which is a dual sub-oscillator eurorack module. There is even have a single version of the 101A if you only wanted one. We opted for the Dual Sub101A and have to admit, we are glad we did. 

What is the Sub101A?

The Sub101A is a 6HP Eurorack Module who’s circuit adds a square wave sub-oscillator to your rack. In layman’s terms, it adds more bass or low end to the output of anything going into it. This is accomplished by tracking an oscillator signal from a VCO and then generating a square wave that is -1 or -2 octaves below that. Needless to say, it goes low!!

You can also mix between the 2 sub-octaves which can give the output a sound similar to the famous Roland SH-101 pulse.

Let’s get on with the build!!

Neutral Labs Elmyra – DIY Build

Neutral Labs ELMYRA - DIY Build

As we bring in the new year, we took a look back to see what we were missing in our studio. We were looking for something unique, something with guts, something to kick a little more ass in the upcoming year.

The neutral labs Elmyra was our answer. This synth was going to be a new type of build for us since this synth was a standalone and not a modular one. We were up for the challenge. In case you were looking for our previous build of the NL NERMAL, it can be found here.

We picked up our white paneled Elmyra kit from our friends over at Synthcube, who also offer the black paneled version as well. It runs on USB power which gives the synth a lot of flexibility. Beginners can rejoice too, its a fairly simple build that took a little over an hour to complete. With that being said, let’s jump into the build. 

What is the Elmyra?

With our love for the SOMA Lyra-8, think of the Elmyra as a “smaller” version of it. According to the neutral labs website, the Elmyra is “a digital/analog hybrid drone synthesizer and platform for sonic exploration inspired by the widely beloved Lyra-8”. It is played in the similar fashion as the Lyra-8 as well with its 6 metal finger pads. With a 10-bit audio resolution, its oscillators gives it a gnarly gritty soundscape…. just right for our tastes. 

As with our previous neutral lab build (the NERMAL), the documentation is clear and concise. It is available via the neutral labs website, along with a user manual and schematics. Another cool thing about the way the kit is packaged is that all of the components are grouped into bags so that all of them can be identified without having to look up resistor codes. Talk about a considerate thing to do for the builder! 


Setonix Synth Marsupial – DIY Build

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

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.
