I was listening to Eurhythmics' "Love is a stranger" earlier tonight, and I finally remembered what this synth was called.
In addition to being Dave Stewart's workhorse synth on the first 4 or 5 Eurhythmics albums, it was Gillian Gilbert's main synth on New Order's Power, Corruption and Lies and Low-Life albums, so give it up for the little Octave Voyetra 8! :D
