Sheets

Eleven distinct landscapes. A palette for every journey.

Verified for version 1.0.4 · Updated October 15, 2026

Each factory sheet combines four complementary instruments and is named after a high mountain traverse. Together they span bright, contrasting, breathy, deep, and wide-ranging families of sound.

Tap the sheet's name at the top of the screen to open the list. Sheets are grouped by the character they were measured to have: BRIGHT, CONTRAST, BREATH, DEPTH and RANGE.

Contour's sheet list: eleven sheets, S-01 to S-11, grouped under Bright, Contrast, Breath, Depth and Range.
The sheet list, grouped by what the measurement found.

The free three

Without Pro you have three sheets: S-03 BEIYIDUAN, S-05 NENGGAO and S-09 YUSHAN, one each from Contrast, Breath and Range. The other eight come with Contour Pro. Locked sheets are drawn with diagonal hatching.

Pitch range

Each sheet has its own pitch range, set by what its four corners were actually trained on, so the ribbon changes with the sheet. Why it works that way is in Known limits.

Your own sheets

With Pro you can compose a sheet of your own. Sheets you bake are listed after the factory sheets.
