Matching guide

Find compatible sounds without losing the groove

Smart Match is a public production tool for narrowing the PULSATRAX catalog before listening. Enter the tempo and musical key of the track you are building, choose how strict the match should be, and compare loops or remixable projects with an explanation of each result. The ranking recognizes useful half-time and double-time tempo relationships while keeping untagged material visible at a lower confidence.

Match tempo first

Start with the project BPM. A loop can still fit when it plays naturally at half or double the tempo, but always check timing and groove by ear.

Use key as a shortlist

Select a known musical key to prioritize compatible relationships. Choose Any when the source is percussive, unpitched, or not reliably tagged.
