Transcript

Waterline is an instrument played by water.

Every key drops a drop, and the bubble it traps rings at your note.

Choose how your notes fall.

Single drops.

A steady drip, in time.

A shower.

A storm.

Or one continuous stream, with glide.

Choose the pool.

Honey gloops.

Quicksilver rings like metal.

Lava hisses into steam.

Choose what falls: water, ink, hail, or glowing embers.

Shape every splash. Make it bigger, slow it down, or drop it from higher up.

Take the microphone underwater, and let a slow swell drive a chorus or a phaser.

Then set the sky: mist, wind, sleet, or a thunderhead.

Fifty eight presets. Everything you see, you hear.

Waterline, for Mac. Drop in at smileyface.studio.

Inside

The liquid, the weather, the mic

  • The splash is the sound

    A click as the drop lands, a thump if it's heavy, then a ring from the bubble it traps, tuned to your note. The splash falls back as softer notes.

  • Eight liquids, and what falls in

    Water, oil, honey, milk, quicksilver, seltzer, lava and glacier, each with its own click, crown and ring. And you choose what drops into it, from water and ink to hail or an ember.

  • Six ways to fall

    One drop per note, a drip in time with your track, a shower, a drizzle, a storm, or one stream that glides from note to note.

  • Change the sky

    Mist softens every attack and wind bends the pitch. Under a thunderhead the drops hit hot, and sleet crushes them. Each sky adds its own bed of noise.

  • Move the mic

    Move the mic from the air, where you hear the splash, to under the water, where you hear the rings. Roll a swell through for chorus or phaser.

  • 58 presets

    Forty of them come with weather. Save one in the browser and it opens in the plugin, because they're the same files.
