What I'm listening to today: "Boundless pad", Mike Lewis
If you want to make the kind of ambient music that sounds like just one giant chord for three minutes, the Novation Peak is a good synthesizer to go with.
This track is three minutes of stately chord progression absolutely drenched in echo. Extremely satisfying. Imagine someone in a big comfy sweater with a big cup of coffee jumping up and down in front of a sunrise yelling "Yes!! Yes!!! This is so relaxing!!!"
