Each item is assembled by hand. The mark of the maker can be found on the surface of the items, showing the efforts to manipulate materials and minimising waste. For us, an imperfect artefact for sale is preferable to a usable flaw in the dump.
This release consists of audio recordings made using circuits based on ICs (integrated circuits or ‘chips’) from the UM series. These DIY EMIs (electronic musical instruments) come from physical remixes, and are bent by design (thanks to Rob Hordijk). The demonstration schematics found in the official datasheets were built, bent, remixed, extended, multiplied and fabricated to facilitate play with a few parameters.
This release shows music composed on computer and expressed as hardware instead of recording. The circuit composition can be viewed as a form of score. The musical instrument voice is technological. The parameters available are limited. Complex frequency output can be made with both UM66 & UM3561 in spite of their obsolescence.
The UM3561 chip was designed to produce sound effects: The chip used in this circuit produces an emergency siren type sound. The UM3561 is used four times. They not synchronised. This DIY EMI has potentiometers to control voltage starve & volume as well as an on/off switch and two touch-pads per IC so that skin contacting the PCB changes resistance and timing/frequency.
The UM66 chip was designed to play popular monophonic melodies: The chip used in this circuit plays Für Elise. The UM66 is used two times. They not synchronised. This DIY EMI has potentiometers to control voltage starve & volume as well as a switch to change the ‘bent’ character of the sound.
These DIY EMIs require a 3v CR2032 battery for power. The output is a mono mini jack (3.5mm). Play with rhythm, melody & noise.
A very familiar journey. Two locations, Lisbon and Seixal. A river in between. A ferry crossing. A journey between north and south of the greater city of Lisbon in Portugal. These are the premises that envelope the project.
The project results from a detailed exploration of timbres and rhythms using various field recording techniques. The result takes the listener on a journey between metal, water, and time.
This edition also includes two collaborations between Matilde and Tone Burst. A silk print printed by Galdéria in Caldas da Rainha (Portugal), and a short audio/visual element—Follow the water. The silk print is a graphic exploration of the project’s useful constraints, while the audio/visual element is a conversation between Matilde, Phil and Barry using recordings of water from the various locations where each one of us was based: Lisbon, Munich and Belfast.
