Harmony Lab vs OpenDeck DJ

Create chord progressions and hear them come to life. Harmony Lab is built for exploring harmony in a way that feels clear and immediate. It gives you a space to build progressions, shape how they are played, and understand how everything connects. You can create progressions in multiple ways. Build them manually, generate them from scales, or follow harmonic relationships. Each approach leads to the same goal: turning ideas into sound quickly. Every chord you add is playable instantly. You hear how it fits, how it moves, and how it feels in context. This makes it easy to experiment, adjust, and refine your ideas without breaking flow. Playback is fully customizable. Choose how chords are played using different styles such as up, down, alternating patterns, or more dynamic variations. You can control octave placement and spread notes across multiple octaves to shape the depth of the sound. Rhythm is part of the process. Use built-in patterns or create your own to control how chords are triggered over time. This lets you move beyond static playback and explore groove, timing, and feel. Harmony Lab also gives you control over the details. Adjust note density, introduce probability to create variation, and add humanization to make playback feel more natural. These small changes can completely transform how a progression sounds. You can hear everything across multiple instruments. Switch between piano, guitar, strings, and more to explore different textures and directions. Each instrument gives a new perspective on the same harmonic idea. The interface keeps things focused. You add chords, shape how they are played, and hear the result instantly.

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.
