SynkEngine Android · from 11/11

New · Windows 6.62.1 · macOS soon · free during the alpha

The DJ console. Every phone plays your live deck.

The alpha, free, on your PC: host the party from a laptop, run the DJ console with two decks and a mixer, put a speech or a karaoke on every phone in the room. The PC and the phones share one Wi-Fi or a hotspot. Nothing leaves the room.

• Two decks, a mixer, effects and loops on your laptop, with no extra hardware.
• Your live deck is the party's song: every phone in the room plays it, in sync. Hand over, and every phone changes song on the bar line.
• Nobody else needs the song: your music files are streamed live to every phone.
• Merged with the rest of SynkEngine: pass the mic around the party, or let everyone sing from their own phone. You stay the master of the party.
• A party, on a whim: open the laptop, friends tap Join, press play.

Scratches and effects are heard on the laptop; the phones play the song itself. MIDI controllers work by MIDI learn. In the picture: Coco and Mimi on the decks, with the nine AI agents who build SynkEngine.

Not sure which? Settings → System → About → "System type": "x64-based processor" takes the first one, "ARM-based processor" the second. Portable versions (no installer, one .exe): x64 · Arm64.

Install, in a minute

1. Open the downloaded MSI (or the .exe for the portable version).
2. Windows SmartScreen may say "Windows protected your PC": this is the normal warning for a new app that is not yet in the Microsoft Store. Click More info, then Run anyway. (The Store version follows the alpha.)
3. Open SynkEngine, create a party, and let the phones join — same Wi-Fi or the PC's hotspot.

The alpha is free. Alpha testers who were sent a code enter it once in the app. The first 108 requesters keep their lifetime seat.

What is in 6.62.1

• The DJ console: two decks, a mixer, two FX units, a sampler, loops, scratch, sync, MIDI controllers by learn — the live deck is the party's song, and a hand-over lands on the bar line. The guide: DJ console guide (PDF).
• Hosting from the PC: the open deck's holder can be made the party's master in one tap on the host PC; a greyed control says why.
• Speech and Karaoke on every phone, from the PC too; music files, YouTube and SoundCloud links as the party's source.
• Requires Windows 10 or 11; a Wi-Fi network or the PC's hotspot shared with the phones; phones on SynkEngine for Android 6.61.6 (Google Play, from 11 November).
