A recreation of a one minute soundscape with song birds, crows, a truck stopping, background noise of car going, and a background noise of a plane overhead.
I switched on and off an old tape recorder. You can hear hum noise like an early synthesizer. The reason why it makes such noise is not sure, but that's the most important part of analog devices. Computer software cannot do that.
Chime sounds from http://www. Freesound. Org/people/urupin/sounds/122056 mixed together with noise, bit depth decreased, and all reversed. And then some other effects applied.
A murky sounding, pulsating, composition with some noise. Two different filters sends the sound to respective stereo channel. No effects added in the modular or in the computer.
