Orfeo runs on any reasonably modern Windows PC and doesn’t need a powerful graphics card. This page lists what you need, what’s recommended for smooth playback of busy songs, and how much disk space to set aside.
At a glance
Component | Requirement |
Operating system | Windows 10 or Windows 11, 64-bit |
Processor | Quad-core, from 2015 or newer recommended |
Memory | 8 GB of RAM recommended |
Graphics | Any built-in graphics from the last decade, with up-to-date drivers |
Storage | Less than 500 MB, plus room for any extra soundfonts you download |
Internet | Not required. Orfeo plays, practises and edits offline; the internet is used only for optional soundfont downloads, update checks and links you open |
MIDI keyboard | Optional. Any USB or MIDI keyboard that Windows recognises |
Smooth playback
Simple piano pieces play smoothly on almost any PC. Dense, multi-instrument songs (a full band or orchestra arrangement with realistic sound) ask more of the processor and memory, which is why a quad-core processor and 8 GB of RAM are recommended.
The falling notes are drawn by your graphics chip. Any built-in graphics from the last ten years is enough, but outdated graphics drivers are the most common cause of visual stutter. If notes jump or the picture stutters, update your drivers first:

Disk space
What | Size |
Orfeo | Under 500 MB, including the GeneralUser GS soundfont (31 MB) |
FluidR3 GM soundfont | 142 MB, optional download |
MuseScore General soundfont | 38 MB, optional download |
Your own imported soundfonts | Their file size |
Edited MIDI versions | Tiny, usually well under 1 MB each |
Extra soundfonts are only downloaded when you ask for them in Audio settings.
Mac and Linux
There are no official macOS or Linux versions. Orfeo is open source, so technically minded users can build it themselves on those systems, but only the Windows version is tested and supported.
