A night train in the rain.
84 loops you can stack and level to taste. Nothing to sign up for, and the mix you built is still here tomorrow.

Tap the heart on any card and the sound lands here, ready for next time.
Eight shelves
Nine, counting the one you build.
Nature
Water, wind and fire. None of the three repeats the same way twice.
Rain
Eight kinds, from a drizzle on leaves to a downpour on a car roof.
Animals
Birds, crickets and frogs, plus one cat who has mistaken you for furniture.
Urban
Traffic, crowds and roadworks. The city heard through a closed window.
Places
Rooms that already have people in them, for when silence is loud.
Transport
Engines and rails, the sounds that put travellers to sleep sitting up.
Things
Keyboards, clocks, page turns. Small machines at their own work.
Noise
White, pink and brown, for the nights a neighbour needs covering up.
Favourites
No hearts yet. Tap one on any card and the sound turns up here, ready for next time.
Roadmap
Ten changes so far. Four on the way.
The loops and the tools come from Moodist, by MAZE. Below is what we added on top of them, and what we build next.
Next
Picked to build next, three at a time.
Sounds that come and go
Thunder rolls in every few minutes and birds call now and then, each on its own timing.
Follow on GitHubUndo for presets and to-dos
Clearing the mix and deleting a note come with Undo. Presets and checklist items get it too.

Merged, and live on this page.
Three mixes on the first screen
Rainy study, Deep forest and Night train start from one click, and the same click stops them.
Favourites, always on the page
The shelf sits at the foot of the page from your first visit, so you find it before you need it.
Every favourite at once
Press Play them all in the Saved panel and your whole shelf starts, each loop at the level you left it.
Mute one sound, keep its level
Mute a loop from the mix panel and bring it back where it was, with no hunting for its card.
Levels that survive a click
Take a sound out of the mix and put it back, and it returns at the level you set.
Presets that say they are playing
A loaded preset turns into its own pause button, and the save box shows the name it is saved under.
