seqSQUARED: The Analogue Pattern Generator

YouTube Published on May 14, 2012 by hexinverterDOTnet

You might remember the video from this previous post. The following is an update with some additional info via Hex Inverter:

"Technically speaking it is a user-programmable analogue switch. It allows users to plug multiple CV/Gate sequencers in (up to 4 at a time) and generate arrangements of those sequencers.

In other words, it can function on a basic level as a simple module that takes, say, 4 individual 16-step sequencers, and turns them into one seamless 64 step sequencer, much the same way any sequential switch does.

What makes it unique, however, is the fact that you get to actually program the order in which the sequencers are arranged (up to 16 sequences long can make up a pattern). You could in other words go (sequencers A to B): A, B, C, D, D, B, C, A, whatever!

Programming is done via a primarily analogue user interface (potentiometers and LEDs instead of rotary encoders and LCDs), so, while the module technically relies on a microcontroller for this programmability, it feels right at home in an analogue modular environment.

The module also includes a couple of unique features (both voltage controllable). One is that it has a built in clock divider, which selects the length of the sequence you are using. The other is a feature I call "Chaos", which is simply a random chance that on a new note, instead of playing the CV/gate from the sequencer you've programmed for it to play, it selects a random one of the sequencers you have plugged in. So, you could create some interesting musical effects by loading up 4 sequencers and CVing the chaos % chance input!

I am offering this project in:

PCB form: Includes a set of PCBs and a programmed microcontroller. Users source their own components.

Universal Kit form: No pots/jacks, etc. included -- just the logic electronics, so users can select their own format

Eurorack Kit form: Includes a beautiful 26HP panel made by Re:Synthesis and all of the necessary panel-mount components to build your own module

Eurorack Assembled Module form: One hand-assembled, fully tested module in 26HP eurorack format.

With all of these packages I offer, I encourage interested builders to look at the Bill of Materials (BOM), which details what is/is not included in all of the kits to help them decide which one is right for them. The BOM can be found at Google Docs, here, and will be updated automatically if any components change:

Once again, it is through the wonderful power of the internet that this is at all possible for me to do. Through the excellent creative project-funding site Indiegogo, I am able to securely collect preorders in order to make this project happen. As you might see, we have already met our funding goal, so this project is more than happening! It is set to begin shipping around the end of July as kits and modules are assembled for folks that have preordered!
