Our verdict on Radium

Radium is a desktop music editor and digital audio workstation for recording, editing, sequencing, and mixing audio and MIDI. It is aimed at producers who want multitrack audio and MIDI editing alongside tracker-style text editing, graphical controls, modular mixing, and experimental sound design. Its open-source license, downloadable demo versions, and support for Linux, Windows, and macOS make it relevant to users who value platform choice and access to source code.

Its feature set is particularly deep for MIDI-centered production. Radium includes piano roll editing, MIDI sequencing, audio recording and playback, and automation for pitch, velocity, effects, and tempo. The modular mixer and mixer strips support a flexible mixing workflow, while granular synthesis, built-in instruments, and built-in effects extend its sound-design focus. External integration includes Ardour, Bitwig, and MASCHINE, and plugin support covers AU, LADSPA, LV2, VST, and VST3. Python and Scheme scripting add another layer for users comfortable customizing their workflow.

The published paid options are Subscription and Buy. Subscription includes download and upgrade access, support, and one year of updates. Buy includes support and one year of updates, while the program continues working after the update period. Demo builds have disabled soundfile rendering and limit simultaneous VST, AU, and LV2 plugins to two, so evaluation has practical constraints. Radium is a strong fit for open-source experimental MIDI producers who want a specialized desktop environment with modular mixing, synthesis, automation, and broad plugin support. Users seeking a verified video workflow or conventional audio-restoration focus should consider a different category fit.
