dsh-pianist

After a long haul of staring at a terminal, dsh-pianist offers a gentler escape: it turns your DeepSeek Harness Agent into a grand-piano player. You type a sentence like "play a Debussy nocturne" in natural language, the model composes a full score, and an 88-key piano renders it note by note while falling notes, water reflections, meteors, and drifting mist ripple with the melody. Think of it as both a mid-day micro-break and a genuine benchmark for how musically fluent a large model really is.

The sound is drawn from real recordings of the Salamander Grand Piano V3, not a synth patch—six velocity layers, key release, string resonance, and pedal action are all present. The playback engine sits on a deterministic timeline, so pausing, scrubbing, and replaying the same piece are frame-perfect every single run, making side-by-side model comparisons immediately audible. Two visual skins are included: Obsidian Gold, a black high-gloss grand with warm gold interiors and a golden flash on every keyfall, and Sakura Pearl, a pearl-white body with rose-gold detailing under a wash of cherry-blossom light. All 88 keys are open to the user as well—glide with the mouse, tap the computer keyboard, or pick notes with arrow keys—whenever you feel like taking the bench yourself.

It is aimed at developers who want a touch of music inside a serious Agent workflow, researchers who need a quick, low-friction way to compare models' musical reasoning and generation, and anyone who simply wants to sit back, listen to an AI play a song, and enjoy a small private concert.
