The first Specral Modeled Grand Piano

MetaPiano is the first Spectral Modeled Grand Piano out there. It was built upon real sound captures from a Japanese Concert Grand Piano and meticulously rebuilt by math algorithms.

The process

It all started with the search for the perfect piano to analyze its sound. Sampleson fell in love with a Japanese Concert Grand Piano and deeply recorded it, capturing every nuance to feed their spectral analysis with high-quality audio sources.

A peaceful studio located in Patagonia gave them the noiseless scenario we needed to capture cristal-clear waveforms with top industry Mics and Preamps.

Then the real process begins. A custom-made algorithm disassembles the audios and extracts the main characteristics for each note and noise.

Finally, Sampleson's Spectral Engine 2.0 generates the sound every time you play it, making every note unique and irreplaceable since it's created on the fly.

Hyper-Detailed Spectral Modeled Grand Piano

MetaPiano was made upon Spectral Modeling, a technique that provides realistic sounds since it's based on real samples and not hypothetical approaches like physical modeling.

It sounds real because it is real: sound is created the same way in nature (stacking simple sinewaves together). This is why it feels organic and warm.

Sampleson have mapped more than 64 groups of timbre components (releases, hammer, key noises, main timbre, resonance, etc) and recreated them by Spectral Modeling, archiving a realistic and warm sound in only 60 MB, and with very low CPU usage.
