That was gorgeous, Jason. Very subtle, gentle and dreamy.
That means a lot Sacred Synthesis, especially given how I love your work and how big of an influence you've been.
Thank you Soundquest! I think that you are right about his use of the CS80. There's a video on YouTube demonstrating how close some of the presets are to some of his tracks (e.g., China). Having said that, he really seemed to experiment with most early keyboard instruments; the list of instruments he used is quite extensive. This particular track was released in 1973, but I believe the recording goes back to 1970 or perhaps even earlier. Therefore, there is no CS80. His main instrument here was a Fender Rhodes, although I don't know the models well enough to tell which. Based on the dates, it is probably a Silver Top/Sparkle Top or a Mark 1 Suitcase or Mark 1 Stage. I'm playing a Yamaha Montage 8, which has a number of nice Fender Rhodes options to choose from. I think a lot of his sound comes down to his use of reverb, and I think the Valhalla Vintage Verb works well.
On the original, there are a number of electric piano overdubs played higher with different panning. I tried to replicate this by having the upper notes of the electric piano panning differently from the lower, so that they would sound like they were coming from different instruments. At the very end, I layered some of the higher notes to double and play an octave higher... so you get the effect of an octave by playing just one note. This doesn’t work for most of the piece, but I was able to bring the effect in at the end nicely with a pedal. So what you get is really something like a live duet.
It has been speculated by several people that the ambient strings were played on a Hammond organ because Vangelis tended to use it that way. (He didn't use a Leslie.) As I happen to have a '57 Hammond, I obviously experimented, and I think the theory fails miserably. I don't know what he used; it may simply have been a real string player.
If anyone likes Vangelis, please check out my other cover of him: Five Circles from the Chariots of Fire soundtrack, which features the Rev2 in the role of the CS80:
