No. You activate once with your key, and after that Backline runs fully offline.

Yes. Each seat can be either platform, and you can switch whenever you like.

Deactivate the old computer from Settings → License, or from your license page if the old machine is gone. Then activate the new one with the same key.

WAV, AIFF, FLAC, MP3 and M4A (AAC or ALAC). Drop a folder of stems and Backline reads the BPM and key from the names, keeps each track name and suggests a group. Your files stay where they are; nothing is copied.

Every output your interface has. Each group can go to a mono output, a stereo pair, or keep per-track outputs, and routing is saved per device and per song.

Yes. If Backline isn’t right for your rig, email us within 30 days for a full refund.

Yes. Without a license Backline runs as Backline Free: 3 songs, 1 setlist and stereo (outputs 1–2), with every other feature working (Detect sections runs on your free songs). Buy a license and everything unlocks on the spot; your library stays as it is.

Yes. You pay once and the license is yours: no subscription, no renewal. Every 1.x update is included.

Backline: 2 computers at a time (say, the main rig and a backup). Backline Team: 6, for bands, touring acts, worship teams, venues and theatre with several rigs or rotating music directors. Any mix of Mac and Windows.

Never in a way you’d notice. It re-checks quietly every few weeks when it happens to be online and keeps working for months if it isn’t. It never stops or locks during playback, and any change that takes something away waits until the next launch.

Open Manage license, enter the email you bought with, and we’ll email you a link. From there you can get a new key: it replaces the old one, and computers that are already activated keep working.

Stripe. We never see your card details. You’ll get a receipt from Stripe and your license key from us, on screen and by email.
