Spectral Modelling Sound Design
Glassy is built on spectral modelling, an approach the developer describes as related to additive synthesis. Sampleson uses spectral models to recreate well-known digital piano sounds and to create new ones.
The spectral models give detailed control over the harmonics across the keyboard range, so the tone can change in a precise way from low to high notes. The instrument includes 20 factory electric piano sounds to start from.
