Already using Lowline?

Lowline is now Linert. Linert 2.0 is a major update to Lowline, at no extra cost. Your songs, settings and license carry over, so you can keep writing bass parts exactly as before.
- On a Mac, it arrives as an automatic update and the app's name changes from Lowline to Linert
- On Windows, it arrives through the Microsoft Store
- Your existing .btab songs still open as they are
- You only need a Highline license to edit guitar parts. You can still open and listen to them without one
Why Linert
Built for writing guitar and bass parts
Most tab software is packed with features for orchestral and full-band scores — far more than you need when all you want is to put one part on paper.
Linert grew out of writing out dozens of original songs. It doesn't just strip things away — it's loaded with every “I wish it could do this” feature we could think of.
However many guitars you stack, every part shares the same barlines. Play them all together and switch parts from the top bar as you write.
Instruments
One license per instrument.
There's one app, and your licenses decide which parts you can edit. Start with either one and add the other any time. Parts without a license can still be opened, viewed and played. Beatline for drums is coming soon.
Basslines, written the way you play them
The editor a bassist built for writing basslines, carried over as it was. Fingerstyle and slap both play back with samples recorded from a real bass.
Coming soon
Drums, in the same song
You'll be able to add a drum part to the same song as your guitar and bass. It's a separate license from Lowline and Highline, and it isn't on sale yet.
Editor
A light, simple, completely new editor.
The editor was redesigned from scratch to feel simple and lightweight. Many shortcuts match Guitar Pro 8, so you'll feel at home if you're switching.
Features
From writing it down to sharing it.
Auto-draft from your stems
Import the stem of your recorded bass or guitar and Linert drafts the tab for you.
No more starting from a blank page.
* Accuracy depends on the recording (a clean, effect-free signal works best) and on how demanding the playing is.
* WAV files only (MP3 and other formats are not supported).
Tab video for your playthroughs
Export a video of your tab moving across the screen. Key out the background, lay it over your playing footage, and your social posts go up a level.
Have it scroll, turn pages every few bars, or show the current shape as a big chord diagram. Pick both the score and chord diagram looks to export two videos in one go. Choose a green screen, blue screen, black, white or any custom background. For Shorts and Reels, lay it across your vertical video as a strip.

Library & autosave
The library puts every score you've written one click away. Linert keeps a backup every time you edit, so if you close without saving, you can pick up where you left off.
Songs are saved as named .linert files in your library folder, and open with a double-click in the Finder or File Explorer. Each song remembers all its parts, mixer settings and audio file location.
Punchy playback with real samples
Playback uses samples recorded from a real bass and a real guitar. Set level, pan and tone for each part in the mixer, and add filter, chorus, delay and reverb. You can even switch tones during playback.

FAQ
- I already own Lowline. Do I have to pay?
- No. The update to Linert 2.0 is free, and your current license keeps working for bass parts. If you want to edit guitar parts too, add Highline.
- Which one should I buy?
- Pick the instrument you want to write: Highline for guitar, Lowline for bass. You can add the other any time, and until then you can still open, view and play those parts.
- Can I write drums?
- Beatline for drums is coming soon. For now you can buy bass (Lowline) and guitar (Highline) only, and Beatline will be a separate license (it's not included in Lowline or Highline). The drum screens you may see in our videos are from Beatline, too. We'll announce the release date and price on this page.
- Can it open Guitar Pro files?
- Yes, .gp files from Guitar Pro 7 and 8. Guitar and bass tracks are imported. You can also export to .gp and MusicXML (anything that doesn't carry over directly is converted to the closest match, and Linert tells you).
- Do I need an internet connection?
- Only when you enter your license key. After that, Linert works offline.
- What if I get a new computer?
- Deactivate your current computer in the app's settings (this removes both Lowline and Highline from it), then use the same key on the new one. Switching between Mac and Windows works the same way.
- Can I import MP3 files?
- Only WAV files can be imported. Export MP3s and other formats to WAV from your DAW first.
- Does it run on Windows or iPad?
- Windows, yes — get it free from the Microsoft Store and activate it with the same license key as the Mac version. iPad isn't supported.
- Can I try it before buying?
- Yes — in the web demo you can pick guitar or bass, write up to 8 bars of tab, play it back and get scored in Tightline. Saving and exporting (PDF / video) are in the full version. Open it in a browser on a computer. You can also get a full refund within 30 days of purchase.
- Where can I learn how to use it?
- A tutorial of about two minutes walks you through everything from entering notes to exporting, right on screen. You can replay it any time from the ≡ menu, and the ? key shows every shortcut. For the details, see the user guide below.
