After I felt confident about my piano tracks, I decided to layer them with some synthesizer sounds. For the intro I played around with an old plugin called Alchemy by Camel Audio (now Logic Pro Alchemy), which features a very neat granular engine. I loaded Spaced Out by Baby Audio, a wet effects generator, and my go-to plugin for spacey reverb and delay, commonly used for vocals but I found it can also give any instruments a lush and dreamy quality. Also, for the first 16 bars I ran the piano track through Portal by Output, an incredibly powerful granular effects plugin, just to set it apart from the main part and keep it interesting.
