Speldosa (Wintergatan Music Box) is an Audio Unit instrument, the result of a unique collaboration between Klevgrand and the Swedish artist Wintergatan/Martin Molin. Wintergatan has primarily worked in the physical world (the Marble Machine is probably the most astonishing example), while Klevgrand has performed its craft within the digital sphere. When these two worlds now meet, the result is something that both visually and aurally inspires the creation of new compelling melodies. Speldosa (Swedish for “Music Box”) is the essence of the shared beliefs of Klevgrand and Wintergatan, and their fascination with minimalism. A simple melody played on a music box can contain an equal amount of emotional power as any symphonic work. There is something about the music box sound that never ceases to fascinate. The instrument itself has been meticulously recorded by Wintergatan and transformed into a playable digital instrument plugin. It features four different models (Modern, Vintage, Antique, and Eternal = Reversed), two different Room models, and an algorithmic reverb. Wintergatan about Speldosa: "I created the sound by sampling a music box using an acoustic guitar as resonance box. I chose the best samples and it was instant magic. The Music Box went on to become the sonic signature for my two bands, Detektivbyrån and Wintergatan, both recognised for their unique sound. The Speldosa has been the secret sauce in my music career and i hope other musicians finds it as useful as i have. There is a special quality to this exact music box sound that lifts it above the novelty feeling of a toy and turns it into a real music instrument. It just sounds so good, that’s really it. And it is a sound that makes you write music instantly - the music comes from the sound itself. During the collaboration with Klevgrand, when they sent me the first beta version of the plugin, i ended up playing around with the sound for three hours, losing track of time. I wrote three songs that day when i was scheduled to actually do something else. That’s what the sound does to me, and i think it will do the same for others." Features: - Four different music box characters - Two room ambiences - Spacious reverb - Optional vibrato - Output level Speldosa works both as a standalone app and as an AUv3 plugin.

Motor is a plugin effect that uses side-chaining to combine signals in new and interesting ways: put in any two signals and they will dance around each other like courting birds drunk on fermented cherries. Use it to gently morph between sounds or rhythmically cut them up, affecting both volume and spatial position. Add life to the plainest signals with vibrato, or destroy them in interesting ways with extreme modulation speeds.
