I was impressed with Prophet VS too, although I only like a couple of the presets. In many ways, it reminds me of my Korg DW8000 although the Prophet has a harsher sound. I started editing a few presets and came up with a few interesting and usable sounds. I like the Vector envelope in the Prophet, although it isn't as flexible as the Vector controls on the Korg Wavestation. Dooley, if you like Wavetable synths, try Waldorf's PPG 2.V. I got it along with Waldorf Attack and D-Pole for under £25 from Dolphin Music.
I tried the CS80V demo and whilst I like the sound, its depth of programmability is more than I can cope with, which is why I went for the JP8 emulation. It is superb; it can produce punchy and fat as well as glossy/glassy sounds. Dual mode is great for layering patches.
The only problem I see with the Arturia delay effect in both synths is that in Sync mode, you can't have a delay line echoing at say, 3/4 of the tempo (dotted quaver) à la David Gilmour, unless I missed something. It's either 1/2, 1/3, 1/4, etc. or multiples of the tempo setting. And the Prophet doesn't respond to MIDI sustain pedal information.
I will listen to your tune now, Gennaro.
