Speldosa, also known as the Wintergatan Music Box, is an innovative Audio Unit instrument created through a special Klevgrand collaboration with the Swedish artist Wintergatan, led by Martin Molin. While Wintergatan has amazed many with physical creations like the Marble Machine, Klevgrand has excelled in the digital realm. The combination of these two worlds results in an app that beautifully inspires users to create new and compelling melodies.

The name Speldosa means “music box” in Swedish, and it embodies the shared values of both Klevgrand and Wintergatan, particularly their fascination with minimalism in music. A simple melody on a music box can evoke as much emotional power as a grand symphony. The unique music box sound continues to capture hearts and ignite creativity.

Speldosa has been carefully recorded by Wintergatan and transformed into a playable digital instrument plugin. This app showcases four different models of music boxes: the Modern music box model, Vintage music box model, Antique music box model, and Eternal music box model, which is a reversed version. It also includes two room ambience options for a richer listening experience and features an effective algorithmic reverb that adds depth to the sound.

Wintergatan describes his experience with Speldosa, saying, "I created the sound by sampling a music box using an acoustic guitar as a resonance box. I selected the best samples, and it was instant magic." The music box has become a unique sonic signature for his bands, Detektivbyrån and Wintergatan, both credited with creating distinctive sounds. He considers Speldosa the secret sauce of his music career and hopes it helps other musicians as much as it has helped him.

There is something special about the music box sound that elevates it beyond a mere toy; it genuinely functions as a real music instrument. The quality is so enchanting that it inspires immediate musical creation—often, the music seems to flow directly from the sound itself.

During the collaboration with Klevgrand, Martin received an early beta version of the plugin and ended up playing with it for three hours, completely losing track of time. He wrote three new songs that day, even when he had other tasks to attend to. He feels that this sound will have a similar effect on others.

Speldosa works both as a standalone app for music creation and as an AUv3 plugin, making it versatile for various music production needs. It includes features like an optional vibrato effect, an output level control, and more. For those looking to explore the app further, sound examples and a user manual for the plugin can be found on the product webpage.
