Now that we have established some basics it is time to take a look at what we are actually going to be doing in this series. I want to start off by giving a list of the Synthrotek Kits we will need in order to complete this series. You can purchase these kits as we go along or all of them upfront (getting them upfront is not a bad idea as we will likely have some live Q&A sessions and it will be nice for you to have the kits ready).
Here at FluxWithIt.com there is a mind set… If you are not thinking beyond intended operation, then you are limiting yourself. To better illustrate this philosophy as it pertains to the studio. I have decided to take you all with me on down the rabbit whole and into a land where an old guitar pedal is a synth, a simple 555 timer chip is a modulation source, a plain plastic box can become a sample manglers wet dream. Luckily with Sponsor Synthrotek I will be able to help you on your journey to Nerd heaven.
Before we take the blue pill and get to tripped out on bending and circuit melding, Lets gather our thoughts.
First we need to assess just what it is we SHOULD know before attempting any of this.
here are some bullet points of what I feel you should know… and I will help assist you in learning. Continue reading →
The Synthrotek Triple Response Dual VCA uses high quality op amps to give you the sound quality you are looking for in affordable kits and completed units. This VCA has three different response curves per channel: 2 Exponential and 1 Linear. The amplitude of EX2 (switch at right position) can be slightly attenuated via 1 trimmer pot per channel on the PCB. This allows for 3 different curves per channel. EX2 has a slightly more exponential curve than EX1. This VCA operates at 0-5V; a 5V CV input will give you 5V point to point audio output. Use over 5V if you want a super ballsy, loud VCA!
Intended for AC and audio use only (DC coupling will not function properly).
– ~5V peak to peak output with a +5 DC CV input
– 2 exponential and 1 linear response per channel
– Channel 2 is normalled to channel 1
– Compact 4HP sized module
– Kits, complete and PCB/panel combos
– High Quality Op Amps
– Module depth: 1 7/8 inches (4.7 cm)
– Max current draw: 1mA on -12V rail, 9mA on +12V rail
I love doing Eurorack kits. They are more affordable than assembled versions. They give you the satisfaction of actually having a hand in the quality of your module. It is simply a load of fun to know that you helped create this new sound source in your set up.
That being said, I have yet to do a video showing how I build the kits and get them up and running so here is a short video showing the latest addition to my Eurorack Modular synth. the Synthrotek EKO
