  • UM DIY Edition

    Ltd. booklet contains UM66 & UM3561 PCBs & information on building the DIY electronic musical instruments.

    Play with rhythm, melody & noise.

    This PCB can be made by a person who knows that:
    components need to be sourced and soldered to the PCBs,
    3v battery power needs to be supplied,
    a cable and an amplifier should be connected,
    before electronic sound can be heard from this release.

    (Battery not included.)
    These DIY EMIs require a 3v CR2032 battery for power.
    The output is a mono mini jack (3.5mm).

    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 minimise waste. For us, an imperfect artefact for sale is preferable to a usable flaw in the dump.

    Includes unlimited streaming of UM Versions via the free Bandcamp app, plus high-quality download in MP3, FLAC and more.

  • UM3561

    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.

  • UM66

    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.

about

<kat no. 14>

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.
