"mid-70's "Hammond Synthesizer" model 102100 Yes, that's right . . those conservative organ folks rolled out a MONOPHONIC 100% Analog Synth back in the day. I suppose they assumed you would park in on top of your B3 . . but few did"

"Hammond 102100 Monophonic Synthesizer. It was made in the USA around 1974-75. It's been estimated that there are between 40-50 in working order left in the world. It comes with the music stand - which is a brown piece of plexi and also comes with the metal stand that has the Hammond logo on it."

You can find a couple of videos of the 102100 Synthesizer here.

"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."
