The workspace is where your files are kept and where kobimusic's tools run on them. This is the short tour: bring something in, run a tool, and take the result away.
bring files in
- Drag files, or a whole folder, from your computer onto the files. A folder keeps its shape.
- Or use the upload button above the files, or right-click an empty space and choose “upload…”.
MIDI files and MusicXML all work, and so does sheet music as PDF, PNG, JPEG or WebP. Right-click an empty space for a new folder, and right-click anything to rename, move, copy, compress or delete it. Nothing of your own yet? The demos folder has MIDI files, sheet music and scanned pages to try the tools on. Files & storage says how much room there is.
run a tool
- Right-click a file, several files, or a folder. The top of the menu lists the tools that fit: “document to sheet music” for a PDF or page images, “sheet music to midi” for a score, “midi to sheet music” for a MIDI file. The same list is under the “tools” button above the preview.
- Each tool says what it will cost in credits, such as “about 3 credits”, before you pick it. One that needs more than you have left is greyed out.
- Some tools ask a question about the file first, such as whether a PDF is a part-book. Answer it, and start.
- Watch the corner of the page. A wheel shows what is running and how many files are through, and the tasks page has the whole account of it.
where the result goes
A result is saved beside the file it came from, with the same name: sonata.pdf gives sonata.mxl, and sonata.mxl gives sonata.mid. If that name is taken, the new file is called “sonata (2)” and nothing is replaced. A tool run on a demo, which cannot be changed, puts its result at the top of your files.
Click a result to open it. MIDI is drawn as a piano roll and plays, and sheet music is set in type and plays, with a bar over the note it is sounding. In sheet music, click a staff to play from that bar, and click an instrument's name to hear that part on its own.
downloading results
Right-click a file and choose “download”. For several files, or a folder, choose “compress into a .zip” first and download the .zip. Sheet music is a compressed MusicXML file (.mxl), which MuseScore, Finale, Sibelius and Dorico all open.
a folder at a time
Choose a folder instead of a file and the tool runs on every file inside it, subfolders too, up to 2,000 files in one run. The menu counts first, with “×12” for twelve files, and says what it will cost. Each result is saved beside the file it came from, so the folders come back as they went in, with a result next to each file.
A run goes on while its page is open. If the page is closed, what had not finished stops, what was already made is kept, and the tasks page can run it again.
automations
When one tool is not enough, the integrations page has a builder: choose tools, join them, and save. The automation is then on the tools menu of every file it could be given, marked “yours”. The site's own are in the automations folder, and opening one shows how it is made. The flow format says how they are written.
credits
Tools cost credits. A credit is a page of sheet music read, or a piece engraved, aligned or cleaned up. Renaming, copying, compressing and turning sheet music into MIDI cost nothing. A free account has 30 credits a week, and Personal has 200 a day. The usage page shows what is left, and limits has the rest.
