Using the Audio Library

All sound lives in the Audio tab. From here you control playback volume, pick melodies and impact sounds, manage MIDI in the Sound, MIDI and Audio Hub, and add a reactive visualizer. The audio you set here is captured into your final recording, so it is part of the creative work, not an afterthought.

The melody library provides around fifty built-in tunes curated for bouncing-ball runs, including Megalovania, Tetris, Fur Elise, Canon in D and the Imperial March. Selecting a melody sets up the note sequence the balls will play in Rhythmic mode, and the notes always play in order, so the tune stays recognizable even as the physics trigger them at unpredictable moments. Melodies with a strong stepwise shape read best, because a listener can follow the line.

The audio spectrum visualizer adds animated bars that react to the music's frequencies and to collision impacts. It is a professional-grade reactive layer you can place into the scene so the whole frame pulses with the sound, not just the balls.

Set your overall volume and balance the melody against the impact sounds before you record. If the bounces are drowning out the melody (or vice versa), adjust the levels here. Always do a quick test recording to confirm the mix sounds right in the exported file.
