As 2019 came winding down, the gang out at Synthrotek sent us over the Roboto Eurorack DIY kit and low and behold, we were onto another build. The Synthrotek Roboto was originally released in 2017, but has quickly become a staple in a lot of musicians racks due to its versatility and uniqueness. 

From the first module in our rack, we have always had our eyes on the Synthrotek Roboto. We were excited to finally take this one and see what it could do. Roboto is known as a vocoder, pitch shifter, speak-n-spell effect processor, vibrato provider, an 8-bit modulator or plain and simple…  a bit crusher.

Now, let’s get on with the build.

As we approach the new year, the Bizmuth Chaotic Signal Router kit for Eurorack landed on our workbench. The Bizmuth is purely what it states it is – a signal router for modular systems. What does this mean? 

According to Bizmuth Modular, you can route switch or combine up to six signals, or generate up to six gates by turning three endless knobs with one hand.

The module has three identical switches with three IO Jacks each: A, B and C. All operate according to the same four step connection sequence: A B C, A-B C, A-B-C, A B-C, and so on. A dash (-) indicates a connection between the signals.

As you turn a knob, the connection sequence of the corresponding switch advances and new connections appear between the three IO jacks. The connection sequence repeats 24 times in one full 360 revolution. That means you have a different patch every 3.75 degrees.

All jacks are also bi-directional, which means you can use them as inputs and outputs. Read that again… you can use them as inputs and outputs. For example, you can route a signal from the B IO jack to A, A and C, or just C, just like you can route two signals from A and/or C to B.
