Joymixa

Joymixa is a live stem-mixing instrument. You do one thing: press buttons to bring instruments in and out, and a song takes shape from your choices. No music training is needed. HOW IT WORKS Every track is a song split into up to 8 stems, the separate instrument layers: drums, bass, vocals, synths and so on. Each stem sits on one of 8 buttons. Depending on the stem, a press starts it until you press again, or plays it while you hold the button. A stem that comes in mid-song lands exactly where it would be had it been playing from the start, so what you add always stays in time. MIX ACROSS TRACKS Joymixa locks one tempo for everything that is playing. When you switch to another track, the stems you already started keep playing, and you can add that track's stems on top. Any stem in the library can play with any stem of any other library track. Every stem is stretched to the shared tempo, so very different tempos can sound stretched, and tracks in different keys are not matched to each other. You choose what plays; Joymixa keeps it in time. AUDIO RENDERED ON YOUR DEVICE The app has its own audio engine. Mixing, tempo-stretching and effects are computed on your iPhone or iPad. Each button shows its stem's waveform and playback position. Tracks are loaded from the joymixa.com library over the internet. EFFECTS Shape the sound while it plays with filter, delay and flanger, using the analog sticks of a gamepad or the on-screen controls. Tap tempo and BPM controls change the tempo of every playing stem at once. PLAY WITH WHAT YOU HAVE Touch works everywhere. If you own a gamepad that your device supports, it turns the app into a physical instrument. A gamepad is optional. ABLETON LINK Joymixa supports Ableton Link, which keeps tempo and beat in time between apps and devices on the same local network. iOS asks for permission to use the local network the first time you use it. You turn it on or off in Ableton's own settings pane, opened from the row in Joymixa's settings. THE LIBRARY The library holds short looping fragments in many genres and tempos, made for live mixing rather than full songs. Every track can be played and mixed by every Joymixa user, for non-commercial purposes; the people who upload them keep all their rights. ACCOUNTS AND PUBLISHING You can play without an account. Accounts, and publishing tracks to the public library, are part of the joymixa.com service. PRIVACY Joymixa shows no advertising and uses no third-party tracking. Anonymous usage statistics are minimal and can be turned off in settings. The privacy policy and contact details are at joymixa.com.
