Older Samsung phones and ringtone tools may require RTX instead of a standard MIDI file. Converting lets you use a MIDI melody on devices or software that accept this ringtone format.
What MIDI is
MIDI is a sequence of note, timing, instrument, and control events, not a recording of sound. Digital audio workstations and notation programs such as GarageBand, MuseScore, and Cubase can create or export MIDI files, which are also commonly shared between music applications.
What RTX is
RTX is a text-based ringtone format associated with older Samsung phones. It represents a ringtone as note and timing instructions; it is intended for compatible ringtone software and devices, not general-purpose music production.
How to convert MIDI to RTX
Online on 101convert.com
- Open the MIDI-to-RTX converter page on 101convert.com and upload the MIDI file.
- Start the conversion and wait for it to finish.
- Download the RTX file. Multiple files can be converted in one batch; the page shows the per-file size limit.
Offline with desktop software
For local conversion on Windows, Awave Studio supports MIDI input and RTX ringtone output. Open the MIDI file, then use File → Save As and select RTX as the output format. Save the converted file locally. Menu labels and available formats can vary by version.
Quality and compatibility
RTX ringtone instructions do not retain all the information in a full MIDI arrangement. If the source contains several tracks or instruments, the converted ringtone may use only a melody line or simplify the arrangement. Check the RTX file on the intended phone or ringtone application because support varies by model.
