From Recording to Stems: A Full Arrangement in 5 Minutes

This guide walks the entire inRadium workflow end to end — from an empty track to a finished, drag-ready instrument part — in about five minutes. Run through it once and the whole loop becomes muscle memory.

Before you start: set up a good reference

inRadium generates a part that fits an existing arrangement, so the quality of your reference matters. Load the plugin on a track that represents the song — ideally a summing / bus track with several instruments — rather than a single bare vocal.

Tip: sum your stems to one bus and remove or turn down the vocal before recording. A clear instrumental reference gives the AI far more to work with.

Step 1 · Record at least 20 seconds

Play your reference track and click the ● record button in inRadium (or arm it first, then start playback from your DAW). The top waveform fills in as you go. You need 20 seconds minimum to generate; the maximum length depends on your tier, and recording stops automatically at the limit.

Step 2 · Pick one instrument and a style

In the INSTRUMENTS area, check one instrument (it's a single choice). Choose a style at the bottom left — Pop by default — and, if you like, describe the sound in the prompt box, for example bright modern pop, warm electric guitar, tight drums.

Step 3 · Click “Play … for Me”

Press the main button at the bottom (it names your instrument, e.g. Play Electric Gtr for Me). inRadium uploads your reference, generates the part and aligns it to your recording. A progress ring runs in the top-right; when it finishes, the part loads and plays automatically, both waveforms in sync.

Each run produces two versions, so you'll have a choice the moment generation completes.

Step 4 · Audition and fine-tune

• Use Version 1 / Use Version 2 — switch between the two takes; the active button lights up. A greyed-out button just means that version is still preparing.
• Shift / Stretch — nudge the part earlier or later, or stretch it slightly, to tighten the alignment by hand.
• Transpose to — try the same idea on another instrument you have access to.
• Upgrade Sound Quality (Max) — render a higher-quality version; the bottom waveform turns orange. Switch back any time with Use Version 1/2.

Step 5 · Drag it into your DAW

Two ways to finish:

1. Drag (recommended): hold Drag into Track and drop it into the arrange area at the start of the project. A new, instrument-named track appears, aligned to the project start.
2. Save as file: simply click Drag into Track, choose a folder, and import the audio yourself.

Bonus · Score the song section by section

Use Parts (the ‹ Part N › switcher in the title bar) to arrange the verse, chorus and bridge independently. Each part keeps its own recording, instrument, style and settings; the number of parts available depends on your tier.
