Reimagining my Piano with Additive Synthesis

Introduction

In this article, I’ll introduce a free sample library I developed called Piano Overtones. This library layers piano samples in a unique way, according to the overtone series, allowing for extensive flexibility with timbre. Let’s dive into the features and functionalities of this innovative tool.

Overview

The Piano Overtones library comprises a series of piano samples designed to work with the overtone series, which enhances the natural richness of piano sounds. Here’s what the piano sounds like without the added overtones:

Features

At the top of the interface, there are options for pedal, noise, and release samples. If the extra noises become overwhelming, you can easily adjust them in the settings.

Next, we have the middle table that allows you to manipulate the fundamental and overtones. By adjusting the first and second steps, you can control the volume of the fundamental note and its corresponding overtones. For instance:

Turning up the first step gives you the fundamental.
Adjusting the second step introduces the first overtone, an octave higher.
Further adjustments yield even more harmonics: the octave and a fifth above, and so on.

It's worth noting that the overtone sounds can be slightly out of tune. This is by design, as the script tunes partials to align with the harmonic series instead of equal temperament.

Series A and B Tables

On either side of the main controls are Series A and B tables, which enable you to create custom overtone combinations. Adjusting the morph slider allows for interpolation between these two tables, creating varied and interesting timbres.

In addition, you can utilize the dice buttons for randomized modifications, generating unexpected and intriguing results.

Dynamic Features

The library contains 45 samples, all with a single dynamic layer and one round robin. The overtone scripting compensates for the limited dynamic layers by allowing you to control the volumes of the overtones based on your velocity. This feature enables you to create layered soundscapes just by how hard you play.

Below the main controls are four knobs for additional sound transformation:

Space Knob - Controls the amount of spacious, algorithmic reverb.
Shape Knob - Alters the attack and sustain characteristics of the sound.
Shift Knob - Changes the tone by playing samples meant for other keys and pitching them back to the played key.
Dune Knob - Generates metallic bell-like tones by random detuning.

You also have the option to click the shuffle button, introducing new random tunings.

Snapshots and Presets

Once you install the library using Pulse Downloader, it will automatically place the snapshots in the correct directory for easy access. Here are some examples of presets included with the library:

Basic - The standard sound, which provides a solid foundation.
Hollow - A softer, airier tone lacking certain overtones.
Gentle Honky Tonk - Utilizes slight detuning for a nostalgic feel.
E Piano / Steel Drum - Other textures achieved through sound manipulation.
Tiptoeing - Metallic sound when played loudly, but normal at soft volumes.
Broken Clock - Eerie sounds at low volumes.
Nightmare - Ideal for horror-themed soundscapes.
