Syltjam 2014 – Recap

Posted on May 6th, 2014

Another fine meetup of geeky synthesizers and nice people!

This time we were gracefully hosted at some friends house in the outskirts of Malmö. The event began at noon on Saturday, with people joining in all afternoon. Many frequencies were produced during the evening, none were recorded.

We hope you will all join us for the next Syltjam!

SJS-ONE General Informations

SJS-ONE is a software defined 8-bit mono synthesizer with a dual (series) switch-cap filter.

Technically, there is nothing outstanding in the design besides perhaps the very capable MAX261 filter which we are, as far as we know, the only ones to use at this point in a DIY-synthesizer.

But the synthesizer has some interesting history that has certainly colored its development and ultimately its sound. The initial version was developed as an instructional workshop for a synth-event called SyltJam in 2011. The workshop idea was to show people how quickly you can design the basic hardware and software required to produce a platform for versatile audio and music generation.

During December of 2011, we decided to do a project!
The idea was to release one acid track every day.

We succeeded with the help of some old friends, and some new :)

Complete track list here.
Download the all the tracks as a ZIP (420Mb) link removed.

Thanks to all the people involved!

Now, it’s January. Time for a new one-track-a-day project…

Syltjam Synth

Posted on December 9th, 2011

During the Syltjam last weekend our good friend STG designed, built and programmed a really nice little synth based on Arduino and a MAX261 Microprocessor Programmable Universal Active Filter(!).

The result was a 4-note polyphonic, supersawtooth, ultraresonantglitchy synthesizer with pitchbend, volume shaping, selectable mono-mode with adjustable portamento and oscillator detune.

This is what it looked / sounded like during the build:

More technical informations available at Forskningsavdelningen.

We didn’t take any good pictures or record any high-quality sounds…
But they are coming, check back again soon.
