Free online NWCTXT to MIDI converter

Use MIDI when a score made in NoteWorthy Composer needs to play in a sequencer, keyboard, or other software that accepts MIDI but not NWCTXT. MIDI also makes it possible to edit note events and instrument assignments in music-production software.

What the NWCTXT format is

NWCTXT is the plain-text score format used by NoteWorthy Composer (NWC), a Windows notation program. It represents musical notation as text and is typically created by saving or exporting an NWC score as a text file; it is not a standard MIDI file.

What the MIDI format is

MIDI stores musical events such as notes, timing, tempo, dynamics, and instrument program changes. Sequencers, digital audio workstations, and many electronic keyboards can play or edit MIDI. Unlike a rendered audio file, MIDI describes performance instructions rather than recorded sound.

How to convert NWCTXT to MIDI

Online on 101convert.com

1. Upload the NWCTXT file on the 101convert.com converter page. Multiple files can be submitted as a batch; the page shows the per-file size limit.
2. Start the conversion and wait for the MIDI output.
3. Download the converted file or files.

The conversion runs on the service’s server with nwc2xml and then MuseScore.

Offline with desktop software

Free route: Use the nwc2xml utility to convert the NWCTXT score to MusicXML, then open that MusicXML file in MuseScore. In MuseScore, choose File → Export and select MIDI as the output format. This requires nwc2xml as well as MuseScore; MuseScore does not directly open NWCTXT.

NoteWorthy Composer: Open the NWCTXT file in NWC, then choose File → Export and select MIDI. NoteWorthy Composer runs on Windows. This direct route avoids the intermediate MusicXML file.

Quality and compatibility

MIDI preserves playable note and timing information, not the page layout of the score. Check the exported file for missing or altered NWC-specific notation, instrument assignments, tempo, and dynamics; unsupported score objects may not transfer as intended.
