"Kittysleep" - on Roland SH-2000

YouTube via organfairy. organfairy is becoming a Friday tradition. I like it. :)
"Lately I have been transferring some of my old tapes to my computer and one of the tapes was a collection of original melodies I made in 1994. At that time I had just got my first two professional instruments: The Roland SH-2000 and the Roland CR-1000 - in fact this is the first melody I ever recorded using the CR-1000. The other sounds are made on toy keyboards: Bontempi KS3400, Kawai MS-20, and the bass was played on a CASIO SA-3 runned through a Boss OC-2 pedal.

It is the original recording so off course I am only pretending to be playing the Roland synthesizer. The cat however, is real....

.... oh and please excuse the small mistakes and the tape noise."

vintage wallington waveform synthesizer

via this auction

Update via swissdoc: I know this little box. It is a student lab unit for education of students in basic physics. The experiment you do with it is called "Harmonic analysis".

The tutor chooses one the offered basic waveshapes (dial above Sample Wave). You put both the Sample Wave Out and the Summation Out to a 2 beam oscilloscope, which you trigger with the sync pulse to get a stable view.

Then the students have to approximate that wave by setting amplitudes and phases of the first 10 Harmonics (no phase for the first Harmonic). In parallel the theory of fourier series is explained to the students.

We have had exactly this machine at University of Darmstadt where I got my grade and PHD in physics."
