Computers are weird. Sometimes things just go wrong for no good reason. Lexicon can suffer from these problems too. Things might get stuck or give strange errors, often they are operating system (Windows/Mac) related.

Here's the first things to try:

Lexicon update

Be sure to use the latest Lexicon version. Lexicon is always under development and new versions always fix bugs and problems. You can update by going to the top left Lexicon menu item and then Check For Updates.

(Mac) Correct Lexicon architecture

This for macOS users only

Make sure you are using the Lexicon version that matches your Mac's architecture. There is an Intel version and an Apple Silicon version.

You can tell if you have Intel or Apple Silicon by clicking the Apple icon in the top left → About This Mac. If it says Chip: Apple M1 or M2 etc, then you have Apple Silicon. Otherwise it will say you have an Intel chip.

(Mac) Permissions

This for macOS users only

Make sure you grant Lexicon permission to use your Documents folder and optionally also your Downloads if you use it in Lexicon.

You can do this in the macOS System Settings ➡ Privacy & Security ➡ Files and Folders ➡ Lexicon

(Mac / Apple Silicon) Rosetta 2

This is for macOS users only, and only for macOS on Apple Silicon computers

Lexicon uses Rosetta 2, which is a macOS program for Apple Silicon computers that allows running some older internal programs. Normally Lexicon asks if you want to install it when you need it. But if you denied the installer, you may need to install it manually. See here how to do that.

Check your security software

If you are running a virus scanner or security software, be sure to allow/whitelist Lexicon so it can operate normally. Lexicon has a few sub-processes that run so make sure they don't get blocked either. These process are called (without .exe for Mac):

• tagger.exe
• audio-analyzer.exe
• beatshift-scanner.exe
• ffmpeg.exe
• ffprobe.exe

These processes are used during analysis, import, sync and when playing tracks. They are a vital part of Lexicon.

Computer restart

Try a computer restart, this can fix problems and is an easy thing to always try.

Cleanup

Lexicon installs a few temporary files, you can remove these so Lexicon re-installs them by running Cleanup from the Help menu. Choose Temporary Files as option there. This deletes the temporary files and re-installs them.

Permissions

Check if your permissions are correct. For example, an external drive that is read-only will cause problems. Mac sometimes sets external drives to read-only, you can eject the drive and re-plug it or just restart your computer to fix that.
