Twenty-one studio-sampled strings, a real bridge layout and an audio engine built for reverb and long sustain — Guzheng plays like the instrument it was recorded from, with nothing to plug in. 二十一根录音室采样的琴弦、真实的雁柱排布，以及为长混响与余韵而生的音频引擎—— 古筝 App 的手感与音色，与被采样的那台真琴一致，无需任何外接设备。
Click a string — or drag across for a glissando (刮奏) 点击琴弦，横向拖动即为刮奏
Every string is multi-sampled and played back through a SoundFont engine — so soft plucks stay soft, and a full glissando still rings. 每一根弦都经过多层采样，并由 SoundFont 音源引擎驱动—— 轻拨仍是轻拨，一段刮奏依旧余音绕梁。
D2 to D6 across a pentatonic tuning, with movable bridges drawn where they sit on a full-size instrument. Jianpu numbers sit on every string so you always know where you are. 自 D2 至 D6 的五声音阶排列，雁柱位置依照全尺寸古筝绘制； 每根弦上都标有简谱数字，指位一目了然。
Reverb amount and reverb time take the room from a quiet practice space to a concert hall, and touch sensitivity decides how hard you have to press for a full-voiced note. 混响强度与混响时间，可把琴房一路调到音乐厅； 触感灵敏度则决定要用几分力，才弹得出饱满的一声。
Drag across the strings for a glissando, hold for sustain, and switch voices when the same piece wants a koto or a pipa instead. 横向滑动即成刮奏，长按延音不断； 同一首曲子想换个味道时，随手切到日本筝或琵琶。
The same twenty-one strings can speak as a guzheng, a koto, a pipa — or a Vietnamese zither. Choose a voice and the whole board answers in it, with the fingering you already know. 同样的二十一根弦，可以是古筝，也可以是日本筝、琵琶， 或是越南筝。换一种音色，整面琴随之而变，指法却一如往常。
The waterfall view scrolls the score down to the strings in time, so a piece you have never seen becomes something you can play through tonight. Slow it down, loop the hard bar, then take the metronome up. 瀑布流视图让乐谱随节拍落向琴弦—— 一首从未见过的曲子，今晚就能弹得下来。 放慢速度、循环难句，再让节拍器一格格加快。
The soundboard is yours to dress. Swap themes to match the piece — or the hour. 筝面可随心装点：换一个主题，去配一首曲子，或配此刻的心境。

For late practice, when only the strings should show.夜深练琴，眼中只余琴弦。
A tuner that listens to all twenty-one strings, and a mixer that decides how the room around them sounds. 调音器听得清二十一根弦；音效面板则决定，这间屋子如何回响。
