Here’s what they have to say about it:
“This is a 6 minute video, but if you have the patience to listen all the way through there’s a lot of change and evolution present.
This is a single patch, all I’m doing it while playing is adjusting the virtual mod wheel and the levels of the three oscillators. Yet there’s so much change in the sound. And I don’t know what other (hardware) synth I could use to get this sci-fi soundscape.
I have a Virus TI which is excellent, and excels at deep space dark ambiences, but I find it doesn’t have the same level of evolution of a single patch which the Iridium does. I also have the Wavestate which is great for constantly evolving soundscapes, but they tend to sound much more new-age.
The Iridium is like the darkness from the TI combined with the evolution possible with the Wavestate.”
