Moog Spectravox

This machine is very well built and I couldn't fault the quality of it. After all its a Moog gear. For me it hesitated a little if this was a keeper or not.. After all an instrument for me is a practical thing that you should use - not soothing that is just "fun to have". I ended up keeping it though. The reason is that the vocoder is not so nice. The most you can expect from the vocoder is a kind of robotic sound that barely make words intelligible - even if you tweak it as good as it gets.

The reason I kept it was that I liked the effect of the filter - especially with the overall frequency change and LFO connected to this. Connecting drums there made them sound very interesting. And I can see other applications where this synth will be very nice.

Also with band filtering of sounds this effect can make a saw-tooth sound like a oboe or other thin instruments or whatever you like.

I wouldn't buy it as a vocoder though.
