Every set you play is a free promo asset, but most go unrecorded — or end up as a muffled phone clip filmed from the back of the room. A recording taken straight from the mixer is the only version worth putting your name on.

DJM-REC is a free iOS and iPadOS app from Pioneer DJ. If your mixer has digital send/return — the DJM-A9, V10, V5, 750MK2, 450 and a few others — you plug your iPhone or iPad in with a single USB cable and record direct in digital, with no analogue conversion softening the sound. The port sits on top of the mixer, so connecting mid-night is quick. You control the peak limiter from the app to kill any digital clipping, and it auto time-stamps your tracks as you go, so building a tracklist afterwards takes minutes. From there you can upload straight to Mixcloud, SoundCloud or Dropbox, or live-stream the set to Twitch, YouTube or Mixcloud Live.

No compatible mixer? You can still record analogue through the device's own mic when it's not plugged into the mixer — lower quality, but better than nothing while you sort gear. The real point is to use what you capture: tidy the tracklist, upload within a day or two while the set's still warm, and don't let it sit in your camera roll forever.
