JH Polymoog Resonator with Voltage Control + Voice of Saturn

JH Polymoog Resonator + voltage control and Voice of Saturn from Travis Thatcher on Vimeo.

Recently finished my J.H. Polymoog Resonator clone and stuck it in a temporary case until I find time to make a nice panel for it. The module is great for changing the harmonics of a simple input signal and the multiple filter modes are very useful. On its own, a very nice module, but I wanted to try to add some simple voltage control to make it more interesting. This was easily accomplished with the use of some vtl5c/3 vactrols. You need two vactrols per frequency band. They are basically used the same way that the frequency pots are used, and are soldered in parallel with the pot connections. I used the holes on the board that are meant for the board mounted pots, since my panel mounted ones were soldered into the jumpers. In this configuration, the pots act to offset the voltage control. I soldered the 2 neg legs together, and then ran a wire from that to the ground of the cv input jack. The 2 positive legs of the vactrols were connected, and soldered to a 1k resistor for protection. This was then soldered to the signal pin of the cv jack. All three inputs were done this way, and I normalled the cv inputs jacks, so if a signal is inserted to jack 1, it goes to all 3.

Voice of Saturn Voltage Controlled Filter - Frac Format

Finally got it finished - the VoS VCF, modules and kits will be released within a week or so on The video quality kinda sucks, as I think I screwed up the lighting, but you get the idea.

Zoroaster Shoutout has an interview with Atlanta doom band Zoroaster about their new album "Voice of Saturn". They give us a nice little shout out (I recorded some noises on the record), and they're awesome.

The League of Automatic Composers

Just got my League of Automatic Composers anthology from alku. Awesome packaging, wooden usb drive with tons of music. If you aren't familiar with the League, read this. The League and later the Hub were pioneers in early computer music, with an emphasis on networked devices and interaction. This is proper nerdy stuff, and a big influence on some of my work.

Next week is going to be a busy one...

Tons of stuff going on next week in recompas land. First, next Wednesday, April 8th, I will be presenting the Voice of Saturn stuff at the Dorkbot Atlanta meeting. I'll be joined by Scott from Curious Inventor who will be showing off some other projects of his, including the stribe1. Also presenting will be Beth Millikan, talking about Freeside Altanta, a non-profit hacker space they are trying to setup.

Then Thursday at 529, recompas will be playing with Themselves (cue immature joke). Should be a really cool show, I've been into Themselves for quite some time, and I think Chris Devoe will be djing the night! You can get your tickets from Ticket Alternative.

Voice of Saturn VC Filter released

Voice of Saturn Voltage Controlled Filter from CuriousInventor on Vimeo.

The VoS VC Filter is based off of a CEM3372 4 pole low pass filter chip, complete with 2 inputs (each with a vca) and a vca on the output. Lots of modulation possiblities. his first limited run of 50 will include the super fun joystick, which is completely modular.

I'm really happy that we've finally been able to get this out the door. Its a lot of fun to play with, and sounds great with the rest of the modules. More details, pricing, etc, here.

recompas <3's homemade lofi psych

The other day I stumbled upon a great blog, homemade indie lofi psych that, as the name suggests, posts all sorts of rare, and unheard music in those genres. I sent the guy that runs the site some recompas stuff, and they've been showing us some love lately. Great blog, I highly recommend checking it out.

In other news: The VoS VCF test pcb run came in yesterday, if all goes well, we'll be releasing kits very, very soon. I'm excited. Also, recompas will be opening up for Themselves at 529 in East Atlanta on April 9th. flyer to come soon.

Voice of Saturn CEM Filter

Coming soon - The Voice of Saturn Voltage Controlled Filter. We're currently finalizing the first version of the PCB, which should be sent out for manufacturing in a few days. The filter is based around a cem3372 vcf chip, the same chip found in the Sequential Circuits Prophet 600. I'm particularly excited about the first 50, as they will have a nice joystick controller built in (if we can find more, we'll make more with them).

sound samples coming soon...
