Show length on a staff under each fingering chart.
Dragging no longer selects text. The line box resizes, rests and spaces can be added, and Save PNG writes the row. Each chart keeps the foot at the top, and the treble staff shows the pitch with a notehead, stem, flags, and dots. Version 0.2.1.

Recorder fingering editor

A soprano recorder tool for arranging fingering charts. Drag a chart, a rest, or a space onto a line, reorder it, set how long it lasts, or take it off. Resize the line box, then save the finished row as a PNG. Baroque fingering is the chart. The foot, with the double holes, is at the top of each chart, and the mouthpiece is at the bottom.

The usual way to run it is one Linux AppImage. That file contains the window and the fingering charts. It does not read sheet music, and it does not include oemer, ONNX, or model files.

Run the AppImage

chmod +x Recorder-Tab-Converter-0.2.1.AppImage
./Recorder-Tab-Converter-0.2.1.AppImage

If the file will not start because FUSE is missing:

APPIMAGE_EXTRACT_AND_RUN=1 ./Recorder-Tab-Converter-0.2.1.AppImage

Open Empty line, or start from Twinkle, opening or Ode, held note. Drag any chart from C5 to D7, or drag Rest or Space, onto the line. Drag a placed item to move it. Choose a duration under it. Remove takes it off. Shorter, Taller, Narrower, Wider, and the corner grip change the line box. Save PNG downloads the finished row.

Build the AppImage

From a checkout, one command:

./scripts/build-appimage.sh

That installs Node packages, builds the app, and writes:

dist/Recorder-Tab-Converter-0.2.1.AppImage

The AppImage is not committed. Keep it under 600MB.

Fingerings

Baroque (English) fingerings are the first choice on the Dolmetsch Online chart for recorders in C (Brian Blood). The soprano is treated in concert pitch: it sounds as written, low C is C5, and the chart stops at D7. Double holes 6 and 7, forked F, and the second-octave thumb pinch are included. Alternate fingerings on that chart are not shown.

Each chart is drawn foot-up: holes 7 and 6 at the top, then 5 through 1, then the thumb, with the mouthpiece at the bottom. A filled hole is closed. A treble staff under the holes shows the pitch and the length: notehead, stem, flags, dots, and rests.
