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!

SYLTJAM 2014 MALMÖ

Posted on April 16th, 2014

Well! Its time again for another SYLTJAM! Everybody knows what this means!? We meet up, bring synthesizers or other nice stuff and then test it out, jam, drink coffe, that kind of enjoyment. Sounds like a good time? You should come!

This year we have a special venue. A really old house with a nice big garden outside of Malmö. its 15 minutes busride from central Malmö.

When: 3th May, Mid day til late in the night.
Where:  Fårabäcksvägen 15 A, Prydesholm
How:  Bus 142 From  Södervärn – Sallerupsvägen

About the JAM:

Trade table – Bring the crap you dont want, put it on table, take something else.
Maybe some cool talks/workshops! (more info will arrive)
Meet people, talk to them, make music/noise/whatever!
DIY-Gear Everywhere!

INFORMATION HIGHWAY!

State of the Devsound

Ok, so the summer is over and we’ve been super busy drinking beers and brainstorming new synth ideas!

Lots of cool stuff in the works… Check out the panel of prototypes above ;)


MFOS WSG – Bigger Caps!

Posted on June 25th, 2013

Iv had the MFOS WSG for a long time, i think i bought it in 2007 and built it over christmas.  Iv allways kinda liked it but not liked it at the same time. Iv heard similar storys about the WSG from other owners. (plz Ray Wilson dont be mad at me!) But its nice to fiddle around with and experiment with. Iv built several different cases for it over the years, this last one is laser cut, painted with acrylics and has wooden sides. Read more »


Batterimaennen – Im a Doctor

Posted on May 11th, 2013

Have you ever wised you could dance to all the music in the universe at one single point in time? Guess what!? Now you can! This song has made all previously created music in the history of fucking forever totally obsolete.  Dont worry, im a doctor.

Electric Santana Band – Oväntat Sväng

Posted on April 18th, 2013

Let us start by telling you a short story about a young boy called Kevin. He lives with his family in southern Finland. One day he met a really old tree and they made a SOUD and started dancing!

SJS-One modular expander

Posted on April 8th, 2013


 
- Would it not be nice if the SJS-One could be controlled by and control your analog modular synthesizer?

- Yes, yes it would.
 
- Is it very difficult to do?

- No, it’s not.

Let me show you a couple of mods you can do with the SJS-One Synth!

 

This post covers the following mods:

  • * Trigger input
    Any short pulse above a few volts will trigger the SJS-One to play a note (selected by CV).
  • * Trigger output
    Fires a pulse every time a note is triggered via MIDI.
  • * CV inputs
    These to connect via schottky diodes and a voltage divider directly to pins A0 and A1 on the Arduino, and can be used to select note to be played when triggered (or you know, whatever).

Basically what needs to be done is to protect the Arduino from ESD and harmful modular voltages. It doesn’t take kindly to ~12V on its inputs (or outputs).
So, we have to add Schottky diodes for super fast clamping to 5V. And for the CV inputs we also have to add a voltage divider, so we don’t loose all those volts above 5V. To keep it simple, we just cut the volts in half, so from a 0-10V CV, we instead get 0-5V. For the trigger output we need to add two transistors to get extra juicy trigger pulses.

If we take a look at the schematics, we see that pins A0, A1, A3, D2, D12, D14 and D15 on the Arduino are unused. Any of these can be configured to do stuf.
But, for now we’ll use A0 and A1 for CV inputs, D2 for trig in, and D12 for trig out.

What I did was to put all the extra components on a stripboard, connect it to the jacks and pots on the front panel, and to the SJS-One. I just soldered wires to the headers between the SJS-One and the Arduino. Since the Arduino has an onboard 5V voltage regulator, I can power the whole thing with my modular PSU using the Vin pin on the Arduino.

Of course we also need to modify the source code for the SJS-One. For this experiment, we modified the Drumstix code. One of the CV inputs is used to select which sound is triggered by the trigger input. Second CV not implemented yet.

Download modified Drumstix code!

Now, to be clear. These mods are just an example. Your imagination and coding skills are the limit!

In a future post, I’ll show how to add external audio input to the MAX261-filter, so you can use the SJS-One as a voltage controlled filter…
