Klevgrand & Wintergatan Intro Speldosa (Music Box) Virtual Instrument


Klevgrand has introduced Speldosa – Wintergatan Music Box, a virtual instrument for iOS, Mac & Windows that recreates the sound of the music box.

Speldosa is the result of a collaboration between Klevgrand and the Swedish artist Wintergatan/Martin Molin, who is probably best known as the creator of the Marble Machine.

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.

“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,” says Molin. “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.”
