Here’s how to create dynamic markings and hairpins (also known as crescendo/decrescendo markings) using the Soundslice editor.
It’s not currently possible to resize a hairpin by dragging its edges. To resize an existing hairpin, remove the hairpin and create a new one.
There’s no way to control the positioning of dynamics or hairpins. This is something we might add in the future.
If you have a hairpin that spans multiple bars, it might be split across two systems — depending on your screen size and zoom level. You don’t need to do anything special in this case; Soundslice will automatically split the hairpin into two separate hairpins, making sure to render the second one with an “open” start, to communicate that it’s a continuation from the previous system.
It’s very common for a hairpin to start and/or end at a dynamic marking:
Soundslice will automatically detect this and position the dynamics so that they’re perfectly centered with respect to the hairpin.
If the dynamics aren’t centered in your slice, it’s likely that the hairpin and dynamic aren’t associated with exactly the same rhythmic position.
