About this game

Description

Supplied by the Steam store

Eidolophone MELODY エイドロフォン~旋律~ is a downloadable Windows composition program built around a simple idea: art grows from constraints and structure.

It is also a from-scratch modern reimagining of Melody Raiser, the small 1999 MIDI composition program also remembered in RPG Maker communities as Music Mucker. Eidolophone is an independent project and is not affiliated with the original program or the RPG Maker brand.

Instead of opening onto an empty timeline with hundreds of choices, Eidolophone gives you five coordinated voices and a clear path from a musical thought to a complete song. Write melodies across the practical range of the human voice, extend patterns to 16 bars, create your own chord progressions, and arrange reusable patterns into larger song sections and forms.

The included templates are not one-click substitutes for composition. They are worked examples of what can be made inside the same system available to you. Change them, study them, or start from a blank pattern and build something that sounds like nobody else.

Features

Compose with a directly editable melody and four structured backing voices, each with its own instrument, volume, pan, and reverb.

Write notes, chords, rests, rhythms, and melodies in patterns up to 16 bars long.

Develop original chord progressions, reusable patterns, song sections, and complete forms.

Explore 72 templates as practical examples, not limits on what the instrument can make.

Hear your work through an included redistribution-cleared SoundFont containing all 128 General MIDI melodic programs and eight percussion kits.

Load alternate SF2 or SF3 SoundFonts when you want a different palette.

Export MIDI, WAV audio, and editable Eidolophone project files.

Load the included hand-composed Showcase Project, Five Lines, One Horizon, to study or rewrite a complete five-voice arrangement made entirely inside Eidolophone.

Choose among more than 30 built-in music-responsive visualizer styles spanning landscapes, light, geometry, and motion.

Use the interface in English, Spanish, Japanese, German, or Simplified Chinese. The four non-English launch translations are machine-translated review drafts and can be refined after release without changing project files.

Included SoundFont

The release SoundFont contains all 128 General MIDI melodic programs plus eight percussion kits. Full credits and license notices ship with the application.
