Tip: Layer 3 backgrounds and tides disappear when you hit a message box, so plan your level around that. For example, you can add a sublevel without layer 3 at the start/midpoint, and include your message there.
These are the 11 note block samples that I decided to rip from Minecraft. I looped some of them for better use with ADSR. If you want an idea as to each sample sounds, there's an SPC in this download that will play each one of the samples in order. There's also this thread that describes how each one sounds.
EXTRA NOTE: This is what was presented by me for the C3 Summer 2018 event.
