Revolt X is a design bench for stringed instruments. You describe an instrument — a lyre, a harp, a zither, or something of your own — and it works out what every string will do before you cut any wire. A design holds a set of strings, each with its pitch, speaking length, material and diameter, and for every one of them Revolt X reports the tension it pulls, how close that sits to the breaking point of the wire, its linear density, its inharmonicity, how far it stretches to reach pitch, and how many cents a millimetre of movement is worth.
The set as a whole gets a verdict with its reasons: whether every string sits inside its tension band, the worst string as a percentage of breaking, the total 💯 load against the frame budget 💰, and the down-bearing a bridge takes from its break angles. Two charts 📊 sit beside the numbers 🔢 — a tension arc drawing each string against the target band, and a utilization plot putting a dot per string against the sixty-five and eighty per cent rules — so a set that is out of balance is visible before you read a single figure.
The gauge optimizer solves a whole set at once. Give it a target 🎯 tension, flat or arched or one figure per string, a ceiling on utilization and on inharmonicity, an optional limit on the diameter ratio between neighbours, and the materials you would rather use in the order you prefer them. It proposes a gauge and a material for each string, and you apply the ones you want. The Bench works the other way, one string at a time ⏱️: fix any three of gauge, tension, pitch and length and it solves the fourth, then sweeps an axis to show where that string crosses into the warning and critical bands, or compares it across fourteen materials from music 🎵 wire and stainless steel to phosphor bronze and gut.
Beats and consonance shows how the strings will sound together — a matrix of roughness or beat rate for every pair, and behind any pair the interval in cents, the nearest small whole-number 🔢 ratio, and the partials that collide. Twelve tuning systems are built in, from equal temperament and Pythagorean through the meantones to Werckmeister III, Kirnberger III, Vallotti and Ptolemy's intense diatonic, each with its deviation from equal temperament and a degree table 📋; you can write your own and compare ⚖️ any two side by side. Tensions read in newtons, kilograms-force or pounds-force, designs carry notes 📝 and a photo of the build, and everything lives on the device — nothing is collected and nothing leaves it.
