Wet, dripping tones.

Low and hollow, like sound bouncing off wet stone. Play single low notes and leave space between them rather than filling every beat; the gaps are most of the effect.

Pair it with the reverb.

Hall or Cathedral turns the drips into a much larger space. With a MIDI keyboard, the mod wheel opens the tone up while a note rings.

Record it and keep it.

Press Record, play, then download the take as a WAV. It is made on your own device and never uploaded, like everything else here.
