ScratchLab vs OpenDeck DJ

ScratchLab is a professional capture and session-logging tool designed for DJs and structured recording workflows. It helps keep sessions organized so takes, notes, and supporting media are easier to manage. With ScratchLab, you can: • capture and organize session data • track takes with clear logging • support repeatable recording workflows • keep performance and practice sessions documented • simplify review and file organization after recording ScratchLab is built for workflows where consistency matters, whether you are documenting scratch practice, recording structured sessions, or managing repeated capture setups for training and review. It is designed to reduce confusion, improve session organization, and make post-session handling more efficient. The focus is simple: a clear, reliable workflow for capturing and organizing DJ session material without unnecessary complexity.

OpenDeck DJ turns your iPhone or iPad into a single-deck DJ player modeled on a professional club media player: a large jog wheel with a spinning platter display, a tempo fader, transport controls, a zoomable waveform, hot cues, beat loops, and automatic BPM and beat-grid analysis. BRING YOUR OWN MUSIC Drop MP3, AAC/M4A, WAV, AIFF, FLAC or OGG files into the OpenDeck DJ folder in the Files app (On My iPhone / On My iPad → OpenDeck DJ), or from a Mac via Finder, and browse them from the deck's BROWSE screen. A demo track is included so you can try everything straight away. ON IPHONE AND IPAD On an iPad the whole deck is on one screen. On an iPhone it is two landscape pages: the player's screen, and the controls (jog wheel, tempo fader, transport, loops) with the beat meter and BPM in view. Flip between them with the page button or a two-finger swipe. PLAY ALONGSIDE THE CLUB STANDARD OpenDeck DJ speaks Pro DJ Link. On a local network it appears as another player next to CDJ/XDJ decks: it can follow the shared tempo and beat grid with SYNC, or take MASTER and lead. It also shares its music: other players list it in their LINK menu and can browse and load its tracks, with BPM, beat grid and waveforms. Link hardware is optional — the app is a complete standalone player on its own.
