About this catalogue & BPM corrections
Tap a row to highlight it; tap the same row again to deselect it.
Database selection never changes Manual BPM Override or the digital BPM display.
Online search can pull large result sets without loading their BPM into the player; online rows can be BPM-corrected on large devices and then become Learned.
Rows marked Verified were measured in this
browser from the decoded file; Learned rows contain a saved
correction; Reference rows are published values.
On large devices, double-click a BPM with a mouse/trackpad or press and hold it on a large touchscreen to correct the database value. This never changes the digital BPM display.
Save a portable copy with your learned BPMs, catalogue, and profile.
