The Rain exciter in Ableton's Tree Tone device plucks individual resonators one at a time rather than exciting them all simultaneously, producing a percussive, mallet-like texture. This bit walks through each of Rain's parameters in sequence, showing how they shape the character and distribution of hits.
Speed sets the rate of the raindrops, though the timing is intentionally randomized to mimic real rainfall. Spread determines the range of resonators that can be triggered, and Center shifts that range toward lower or higher resonators. Lo Cut and Hi Cut shape the tone of each mallet hit itself, with Lo Cut adding presence and Hi Cut softening the attack.
