Hammond 102100 Analog monophonic synthesizer demo

YouTube via sounddoctorin
"Bob Weigel of Sound Doctorin' demonstrates the Hammond 102100 synthesizer, a rare analog monophonic unit capable of some warm sounds and somewhat flexible through use of an array of preset switches. Sliders for wind (noise), tuning and volume. But 7 buttons each for waveforms (32' square, 32' saw, 16' of the same, 8' of the same, and 4' of a pulsey saw), filter mode, Width (one shots and repeating) and rates for vcf, envelopes for vca, pitch bend envelopes/portamentos, and modulations. Presets are French horn, Tuba, Violin, Sax, Clarinet, and 'space echo'. Cancelling presets leaves one with whatever the button matrix has selected then. Only one button in each row of 7 can be pressed at once. But as you see some useful combinations do come up and it's certainly a useful synth for the studio."

Hammond 102100 analog synthesizer tune up!

"Bob Weigel of Sound Doctorin' ( Http://www.sounddoctorin.com ) runs through the tuneup procedures for the rare Hammond 102100 synthesizer. See also video doing sound demonstrations. These are a monophonic synth with a single vco and divide down square wave arrangement. Then footages are combined to create stepped saw waveforms which may be selected instead of squares from 32' to 4' and run through the VCF and VCA sections with modulations. But controls are limited to sliders for wind (noise) and tuning and volume, and preset buttons for 7 each waveforms, filter modes, sweep rates (repeating and one shot), Envelopes, and modulations. Still there are some very nice combinations and the sound is very warm though noisy base line so far. I may need to replace those electrolytics that measure a little high on esr meter."
