Scratch DJ Technique - 1 Click Flare
1 Click Flare - Similar to an og flare, but the fader only closes and opens once in the middle of a forward or reverse movement, creating 2 notes per movement. When done on both the forward and reverse movement in succession, it is known as a 1 click orbit, creating 4 notes. Keep in mind that any flare where the same amount of clicks is repeated in succession is known as an orbit.
