Sacramento Audio Waffle 70 – Virtual Programming

Tired of the same old same old quarantine life? Check out the Sacramento Audio Waffle 70 via virtual programming on Sunday, October 18, 2020. 

The Sacramento Audio Waffle has been a long standing NOISE event that features artists from all over the US. From guitars to synths, to anything else that can make noise, the Audio Waffle is the loudest breakfast in the valley!

Reverse Landfill Pentamix – DIY Build

Reverse Landfill Pentamix - DIY Build

Reverse Landfill’s unique approach to modular synthesis is something that they are becoming known for. Their cryptic silkscreens on their panels also makes for some interesting patching if one is unfamiliar with the modules. The Pentamix is one of Martijn’s newer modules that helps bring all of the other Reverse Landfill modules together.

A 5-channel audio mixer, the Pentamix’s real magic happens when you patch the inverted output and use the another output to send out to an effect and then back again into the Pentamix.

With its 555 pentagram, this mixer brings a new dimension to ones rack… but enough about the module, let’s get onto the build… 

Resistors and Diodes...

Start with the resistors on this build. There are not very many of them (12 to be exact) and their polarity doesn’t matter. Each resistor set is marked so its easy to figure out what goes where if you can read a BOM.  You can find all of the Pentamix’s documentation on the Reverse Landfill website for quick reference. 

Diodes are next and one thing we love about Martijn’s modules is the extra power protection. The diodes (x2) will protect your module if the power is reversed for any reason. The 2x resistors next to the diodes are there for extra protection. One thing to know about diodes is that their polarity does matter. You want to be sure that the black line on the diode lines up with the silkscreen on the PCB. A quick tack down of these and its time to move onto the IC sockets and caps. 


Synthrotek VERB – DIY Build

Synthrotek VERB- DIY Build

As described by the Synthrotek site, “the Synthrotek Verb is a reverb module like no other. This three PT2399 unit offers a warm tape saturated spring reverb like sound but with the added flair of the subtle modulation which truly makes it shine.” This was enough for us to decide to take on the VERB on for the next build of September 2020.

Unlike a lot of other reverb modules, this one does not require a “tank” to produce its reverb. It relies on the x3 PT2399 circuits that were previous utilized in other delay modules. 

The PT2399 is back … again.

We won’t go into all of the technical jargon like we have in previous builds (see Synthrotek DLY and Waveform Magazine Delay builds), but we will say that the PT2399 is a very versatile IC. It can be used for delay’s, echo’s and even reverbs (as this module uses them).

To keep it simple, the IC takes in analog audio input and converts it into digital stream of bits to add a digital delay to it. This audio delayed audio signal is then provided as output (ie. perfect for these module types).

On with the build ...
