Baldwin Syntha Sound

"SYNTHA SOUND analog mono synth from the 1970s. I know BALDWIN made these but someone has put a VOX badge on the front. Hmmm? I don't know about a VOX version, but maybe? This one (last I heard) was not functioning. I don't know how much or how little - but not right. So understand and bid accordingly. This is fairly heavy but will be packed well. It has a nice sturdy wood outside, so it is strong. Some slider tips missing - see photos for details. These are great COOL synths very few people have ever seen!"

If anyone knows more about these, feel free to comment.

Update via an anonymous reader:
"The Baldwin Syntha Sound:
Yes, although limited in function, these are cool, and generally pretty good/unique sounding monosynths. Most definately Baldwin - the Vox badge on this particular unit was probably stuck on later on. I really don't think Vox had anything to do with these.
Baldwin's schematics for these units are dated April 1973. This is the model they called the portable syntha sound, and this version does seem to be quite rare. I have seen only two of these in person - one of which I own and another which was in my shop for repairs. They were purchased in two different parts of the country, yet had sequential serial numbers (very low). However, the same basic unit was included in some of their mid-70's home organ models and these are slightly more common.
The portable model SS has a built in 12 watt amp (common to many other Baldwin products), speakers, and a great sounding reverb. It has preset sections (Trumpet, Trombone, Saxophone, Cello)- labled "pre-set" and "Flutes" of various footages, and then also the synth section: which they labled: "spectrum shaper" - with 8', 16', and 32' octaves- producing square, pulse or sawtooth (either alone or in combo). Other functions include a noise generator, high, mid, and low pass filters (used either,alone, in pairs, or "all-pass") - the filter can feedback and squeal. There is portamento too.... Modulation, however, is a bit limited: vibrato "standard" or adjustable with "rate" and "extent" sliders (sine or repeat).
The two big chunks of wood on the control panel are unusual - they are temporary switches. One shuts off the tremelo (which feels counter-intuitive) and the other triggers the "spectrum shaper" CV (which is only slightly more useful). The thing that the owner of this unit should know, is that the slider pots are of pretty poor quality and are easily broken - and also, that they used two different versions of these - which mount differently, of course - and the earlier versions are hard to find - a partial 3rd unit was used to restore the two I have had here. -Hope that clears up some of your questions.

I forgot to mention that it has an external input jack which goes though the filter.

Baldwin Syntha-Sound and Tempo-Matic

Ran into these on a post on Vintage Synth Explorer. I never knew these existed. Title link takes you to Audio Playgrounds Synthesizer Museum page on Baldwin. Click through to get a bigger shot of each. Oddly you have to click on the Syntha-Sound picture on the first page to get to the Tempo-Matic picture.

I found the following in the AH archives regarding the Syntha-Sound:

"Interesting box, but not what I recall as a terribly remarkable sound.
Three sections: a variable synth department, some preset synth tones
(trumpet, trombone, sax, cello) and a monophonic organ section comprising
flutes at 16', 8', 4', 2-2/3' and 1-1/3'. I think they can all be used at
once, but they were all monophonic.

Some controls on sliders, a lot of mode selection controls on pushbuttons,
like the VCO octaves, waveforms and 'mode' controls, which essentially set
you up with preset envelopes. The filter, as I recall was a multimode and
had at least low-pass and bandpass modes.

hmmm, what else? Built-in spring reverb, built in amplifier, *and* a speaker
on the side of the unit. There are a couple of push bars right above the
keys- one of them shut off the LFO momentarily, if I recall. Three octave
square-front keyboard, more wood than most synths (in fact, essentially all
wood except for the keys and front panel, don't remember what the bottom is
made of). I think there's an external input, but I don't know whether it can
be routed through the filter/VCA or not.

Different architecture, and an interesting concept. I don't remember being
blown away by any particular characteristic of the sound though...

There is also a little piece on the Syntha-Sound in this article.

I haven't found anything on the Tempo-Matic.
