1978 Keynote Musical Instruments Stage Scorpion Ad

via Retro Synth Ads where you'll find the write-up.

"Keynote Musical Instruments Ltd. Scorpion Stage Synthesizer 1-page advertisement from page 189 in International Musician and Recording World December 1978 (UK)."

Update: Details are in:

"The Scorpion is being advertised as the first British lead line synthesizer. It is not the first British synthesizer by any means but, as far as I know, it is the only one that has been introduced to compete with the smaller stage synthesizers like the Micro Moog, Arp Axxe, etc.

It is simple to understand, easy to operate synth, aimed at the person who has been frightened off using a variable synthesizer because of his/her lack of understanding of synth jargon and technical terms (the owner's manual contains information on not only how to operate the synthesizer, but also how the different parts of the synthesizer affect the final sound.)"

Two oscillators
Programmable with eight presets
Keyboard pressure bend
Delayed modulation

You can find the full specs in this new Retro Synth Ads post.
