Synthrotek XFD - DIY Builds

The gang over at Synthrotek have done it again with another crossfader module, only this time it can work with video as well. According to SR, “the XFD is a CV-controlled vactrol-based crossfader module, ideal for both audio and bipolar CV sources.

It can be used as a cv-controlled attenuator: connecting just one input allows the signal to quickly fade in a VCA-like fashion.” For our build, we chose the audio version of the module whereas both are currently available in the links below.

Synthrotek Crossfader (CF) and 2hp Buff Mult - DIY Builds

We all know that you can’t have enough VCA’s in a modular system. The gang over at Synthrotek recently released a new VCA module in their slider series and we had to pick one up. This kit is different from most of the other Synthrotek kits we have assembled in the past, in that it is an SMD kit. With that being said, this module and/or build is not for the novice builder. 

You will want to have a few hours of practice on SMD before jumping into this one. 

The slider series by Synthrotek looks great and along side the other slider modules, the VCA fits right in. As with most SMD builds, we generally use a digital microscope, but on this build we did not. We not only used our normal 60/40 solder but we also used solder paste on some of the build. Let’s get on with the build shall we?

Erica Synths Polivoks Envelope Generator - DIY Build

With October coming to a close, we decided to take on one more build for the month. This time we took on the Erica Synths Polivoks Envelope Generator kit by Synthrotek. We were lucky enough to get our hands on one of these modules being that the recent supply chains have been challenged. 

Many of the DIY kits are either sold out or components have been scarce. Upon getting the kit, we took a moment to review the BOM and Assembly Guide provided by Erica Synths and dove right in upon receipt of the kit.

Division 6 Dual Mini Synthesizer - DIY Build

D6 - Completed Module Close

Division 6 is the maker of unique modular and desktop synths and one of their latest creations is perhaps one of the coolest. The Dual Mini Synthesizer is a two part modular synth that houses two complete synthesizer voices. They are based on the Business Card Synthesizer with all its 8-bit goodness, but adds CV inputs for most of the controls. With that being said, it is also makes the perfect pair partnered with the Dual Mini Sequencer that we built awhile ago.  

Since we didn’t go into great detail on the Dual Mini Sequencer build, we decided to do this one a proper write up and review. Now, enough about all that, let’s get on with the build!
