the mini Organ Dronor

"I recorded a new video with much better sound. Now it finally sounds like it should.

The power to drone, right in your hand! The mini Organ Dronor is a smaller version of the "Organ Dronor" analog drone system I've been developing over the last 2 years. Unlike most simple drone machines out there my design features a custom waveform which add a lot of interesting harmonics. For the controls it uses a single knob to set the overall frequency and a light sensor to control the relative frequency between the oscillators. This results in a very intuitive interface and allows for outside modulation using any light source.

Features
-Fully assembled and tested
-simple 9V battery operated (9v not included)
-small! just 5x5cm
-Light controlled droning
-standard 1/4″(6.35mm) output (different from the picture wich shows a 1/8″ jack)"

The mini Organ Dronor

"The mini Organ Dronor is a smaller version of my Organ dronor design. No filters, no fuss, just raw analog droning fun. The pitch is controlled with the knob and the little black tube houses a light sensor wich controls the relative pitch between the oscillators."

Note: I created a JvGrieken label for posts moving forward. A search on JvGrieken will bring up prior posts.

"12-12-2011 @ HKU school for arts, Utrecht.

I've always wanted to combine dance and light with my work in electronics and music. So I made a light sensitive wireless suit wich translates the light intensity from various parts on the body into raw midi data.

More info(including arduino code and how it works):

Thanks to Charlie Duran for really showing what the suit can do.

This is just the first in a series of projects involving the suit so stay tuned for more."

Organ Dronor v2.8 EDP wasp filterclone

"Added my first OTA filter. A jurgen Haible clone of the popular EDP wasp filter. I really love the sounds Im getting here."

"This is a project I did for evaluation at HKU school of fine arts Utrecht. It uses an arduino to process the inputs from the light sensitive resistors and outputs it as a midi message. Software on the computer then turns this value into the corresponding note. All the sounds are made in Ableton Live and in the second part of the video you can hear the 4 different modes, instruments, synthesis, samples and drums."

"This project has been a long time coming, but the first prototype is finally done. Still some minor changes to be made, mainly around the filter and a CV input for the filter. Im currently developing a kit, contact me if you're interested.
-2 triangle oscillators with fine tune knob for those tearing slow drones.
-2 triangle LFO's with interchangable capacitors to set the range.
-LFO amount for both sides
-LED reflector rate indicators
-custom filter with resonance control
-on/off and volume

sorry for the bad video quality, my camera is old and doesn't like low lighting conditions. The audio was recorded raw into ableton live directly from the output without any filtering or effects."

Lunetta Workshop

YouTube via JvGrieken | February 09, 2011 |

"A workshop I gave as part of the seminar period at the HKU school for fine arts. 4 days of noise and experimenting with cmos chips, a great way to learn basic electronics and sound synthesis. The entire workshop is solder free with the use of electronic breadboards and simple basic components. We worked on a need to know basis so students would first make something and afterwards the underlying theory is explained.

Thanks to everyone involved and especially HKU for making it possible in the first place."

Light sensing sequencer

YouTube via JvGrieken | January 19, 2011 |

"A project I did for halfterms at HKU 15-12-2010

The entire project works with analog electronics. I used an overhead projector to project the images on an 3m x 1,50m screen. Behind the screen are 8 seperate piramids capturing the light and converting it into a pitch, the less light, the higher the pitch. The 8 step sequencer runs through the pattern and plays the corresponding pitch. I also added a filter and a control panel for the tempo, pitch and filtersettings."

"An everlasting work in progress, bends so far:
-8 individual volume controls
-51 headerpins patchbay including synth sounds, sequencer glitches and drum rhytm glitches.
-6 patchable toggleswitches
-1 global pitchcontrol
-lcd spotlight and colourchanging led(not on the video)"

Light Noise

YouTube via JvGrieken | September 15, 2010

"This is the first test of a series Im working on for a school project. The series is about intuitive semi random musical devices wich will be controlled by a variety of natural and unnatural sources.

This first prototype is an effort to generate complex patterns sound patterns using light and basic electronics. It's based around two 40106 hexinverter cmos IC's with 12 Light controlled oscillators. They are all competing with eachother to produce a very wide range of sounds and patterns."

Musical greetingcard drummachine, first tests

YouTube via JvGrieken | August 13, 2010

"This idea was inspired by this excellent topic over at EM: http://electro-music.com/forum/viewto...

I was using my 4017/4066 sequencer wich is gating a hallmark musical greetingcard wich plays the song "twist and shout" by the Top notes. I used 2 oscillators and a xor gate to affect the timing resistor causing the pitched sound.

Going to try multiple cards and more messing with the timing resistor next."

Lunetta1: Insanity session

"This is a one take recording session with all the modules on the board beeing used.
The audio was recorded seperately in ableton live, no editing, just a springreverb effect added for a little depth."

4069 triangle LFO test

YouTube via JvGrieken | August 11, 2010

"This is the first test run of my new 4069 triangle LFO module. The right one on the video is connected to a 4046 VCO wich is fed directly into the speakers. The camera mic filters out all the high pitches but in real life the triangle gives a real smooth transition and goes down to 2 cycles per minute."
