Free online RTX to MIDI converter

A ringtone saved as RTX may need conversion when a sequencer, keyboard, or player accepts MIDI but not the phone-specific file. MIDI also lets you edit and reuse the ringtone’s note events in music software.

What the RTX format is

RTX is a text-based ringtone notation associated with Ericsson mobile phones and ringtone-composition software. It stores musical instructions rather than recorded sound, so you may encounter it in old phone backups or ringtone collections.

What the MIDI format is

MIDI stores musical events such as notes, timing, and tempo; it does not contain the sound recording itself. Sequencers, notation programs, keyboards, and many media tools support MIDI, making it useful for editing, playback with different instruments, and sharing musical parts.

Quality and compatibility

Because RTX and MIDI describe musical events rather than recorded audio, conversion does not preserve a particular phone’s instrument sound. The MIDI playback timbre depends on the synthesizer or instrument used. Check the converted file’s tempo, pitch, and note lengths; ringtone-specific instructions may not map identically in every converter.
