How can I prevent that new tags are automatically added to my tag library, when new tracks are analyzed? I want to maintain an own, fixed set of tags and want the library to adhere to that

Hi

Recently changed from pioneer to denon, and i have all my playlists in recordbox, exported them all in lexicon and then sync with serato, non of my tracks have a beat grid?

any tips?

Is sustained HIGH CPU usage in Lexicon states expected behavior, or do these numbers indicate a runaway audio processing / render loop?

System is a MacBook Pro M4 Pro Max, 64GB RAM, macOS Tahoe 26.5, Low Power Mode disabled. (using latest lexicon as of 2026.06.03) The issue is observed after the application is fully loaded and stable (not during startup or import). The library is not new, i'm not doing any batch processes or running anything special in lexicon other than hitting the play button.

During active song playback, Activity Monitor shows Lexicon Helper (Renderer) at ~55% CPU with ~1400 Energy Impact, while Lexicon Helper (GPU) sits at ~15% CPU with ~500 Energy Impact. This by far and away much higher than any other app... it's just doing song playback. No visualizers etc. I notice the audio crackles when moving the mouse over any part of the lexicon interface... and also the waveform stutters and is not smooth at all (this has alwasy been the case).

When playback is stopped but the app remains open, Lexicon Helper (Renderer) still shows ~40% CPU and ~700 Energy Impact, while Lexicon Helper (GPU) drops but remains active at ~2.4% CPU and ~60 Energy Impact.

I don't have audio issues with any other app on my system, or runaway cpu numbers for any other apps.

The main pattern is that the renderer process does not return close to idle when audio is not playing, and overall CPU usage remains elevated in both states, with only partial reduction when playback stops.

Edit: just in the 10 mins since posting this, without a song playing and the app sitting idle.... Lexicon Helper (renderer) is up to 2000 Energy Impact and 80% CPU. After waiting for several minutes without touching things, energy/cpu values drop way down (ie. 50 & 9)... then climbs again quickly to the numbers sbove (700 & 35-40 cpu).

Edit 1hr later... tracks just playing in the background while i work on other things: Lexicon Helper (Renderer) {{business.name}} || Email Notification || Missed call from {{contact.phone}} shows Energy Impact = 2400, CPU = 82%

Using the track-finder to search spotify playlist tracks in my lexicon library

came across this example of Kungs - Regarde-moi which lexicon couldn't find. it is in my library however, cleanly named and labeled so i'm surprised it couldn't pick this up. what are the criteria for finding/matching tracks?

thanks
