What’s the difference between setup and portable?
Setup installs CMDX, adds the selected shortcuts, and includes an uninstaller. Portable is the complete application in a ZIP: extract every file and run CMDX.exe. Both include MidiX, and both save preferences in your Windows user profile.
How do I update CMDX?
Close CMDX and MidiX, then run the newer setup for an installed copy. For a portable copy, replace the entire extracted folder. Keep your own music files outside that folder. New CMDX releases and downloads are posted on this website.
Why can’t I hear my MIDI?
Silent is the default audio mode. Open MidiX Audio Settings and select System MIDI with an available output device, or a configured KDMAPI backend. Audio File mode plays a separate recording with optional libmpv. Read the audio guide →
Can I run MidiX without the visualizer?
Yes. Launch CMDX.exe --midix --gpu software. The studio and audio playback remain available, while the OpenGL preview and video export are disabled. Graphics troubleshooting →
