The DJ Remote Workflow

NexaDeck on Your Laptop. NexaLive on Your Phone. Total Control.

The best KJs are entertainers, not laptop operators. NexaLive's Mobile DJ Panel connects to NexaDeck through the cloud, giving you full show control from any phone, anywhere in the venue.

Play, Pause, Skip

Full transport controls from your phone. Start the next song, pause for announcements, skip a no-show singer — all without walking back to the booth.

Key & Tempo on the Fly

Drop the key two semitones for a singer who needs it. Speed up a slow ballad. Adjust pitch and tempo from your phone with SoundTouch DSP — natural, not robotic.

Manage the Rotation

Reorder singers, add walk-ups, mark someone away, slot them back in when they return. The entire rotation is in your hand, not chained to a screen.

Accept Requests Instantly

Incoming song requests appear on your phone with automatic library matching. Accept or decline with one tap while you chat with the bartender.

Works From Any Network

The Mobile DJ Panel connects through the cloud relay — it works on any WiFi, cellular, even from a different building. Your show keeps running.

Audience Display Stays Live

While you control from your phone, the audience display keeps showing lyrics, the queue, and your branding. Two screens, one seamless experience.

The KJ Struggle Is Real

Every Working KJ Knows These Problems

Professional karaoke DJs have been underserved by software for over two decades. Paper slips still litter DJ booths. Key changes still sound robotic. The DJ is still chained to a laptop in the corner. It doesn't have to be this way.

×
Legacy software was designed for Windows XP

PCDJ Karaoki, CompuHost, Karma — all built in the early 2000s with minimal innovation since. Brittle codebases, dated UIs, and crashes during live shows are just accepted.

NexaDeck is built from the ground up with modern technology

A Rust-powered audio engine, modern React UI, and architecture designed for reliability. Built in the 2020s for the 2020s.

×
Paper slips create chaos and frustration

Illegible handwriting, lost slips, no way to verify songs are in the library, and singers have no idea where they are in the queue.

NexaLive replaces paper with zero-friction digital requests

Scan a QR code, search the catalog, submit in 30 seconds. No app download, no account. The DJ sees requests with automatic library matching.

×
No mobile control — you're tethered to the laptop

When you need to adjust the rotation from the stage, mingle with the crowd, or handle a question at the bar — you can't. Legacy software has no concept of remote control.

NexaLive Mobile DJ Panel works from any phone, anywhere

Play, pause, skip, manage rotation, handle requests, adjust pitch and tempo — all from your phone through the cloud. Works from any network, anywhere in the venue.

×
Windows-only locks out Mac and Linux DJs

PCDJ, CompuHost, Karma — all Windows-only. If you prefer macOS or your venue standardized on a different platform, your options are severely limited.

NexaDeck runs on Mac, Windows, and Linux from day one

Cross-platform from the start. Same professional experience regardless of your operating system.

×
Key change sounds robotic and unnatural

Basic pitch shifting introduces metallic tones, chipmunk effects, and unnatural warbling. Professional singers notice immediately.

Rust-powered audio with professional DSP processing

SoundTouch DSP with independent pitch shift (±12 semitones) and tempo control (0.5x–2.0x). Multiple DSP modes including Rubberband for natural pitch preservation.

×
No way to build your brand or promote shows

Legacy software treats the DJ as invisible. No web presence, no show schedule, no discoverability.

NexaLive gives every DJ a branded discovery page

A branded hub page with live show status, upcoming schedule, browsable songbook, and QR code access. Share it on social media or print it on business cards.

A Day in the Life

How a Professional KJ Uses NexaDeck + NexaLive

Follow a working KJ through a typical weeknight show to see how the desktop + phone combo transforms the entire experience.

6:30 PM — Load-In

Setup Takes Five Minutes

NexaDeck launches with your full library ready — no re-scanning. Connect the projector for the audience display. Pull up NexaLive on your phone and confirm the show is live. Buffer music starts automatically.

7:00 PM — Doors Open

Requests Start Before You Touch the Mic

Patrons scan the QR code and start browsing. Within minutes, your request queue has incoming songs — each matched against your library. You accept them from your phone while chatting with the bartender.

7:30 PM — First Singer

Professional Audio From the First Note

The first singer needs a key drop. You adjust from your phone — the pitch shift is seamless, powered by SoundTouch DSP. CDG lyrics scroll on the audience display with your branding.

9:00 PM — Peak Hour

Full Rotation, Zero Stress

Twenty-five singers in the rotation. You're on the dance floor encouraging a first-timer, managing the queue from your phone. Smart rotation handles fair ordering. Singers mark themselves away and get slotted back automatically.

10:30 PM — Late Night

The Crowd Is Engaged

Patrons check queue position from their phones. They browse songs and discover tracks. Someone shares your NexaLive show page and new faces walk in. The audience is part of the show.

1:00 AM — Last Call

Clean Wrap, Tomorrow Is Already Set

NexaDeck shows the remaining rotation. After the final performance, buffer music fades back in. NexaLive marks the show as ended. Your hub page already shows the next show date.

Why Professional KJs Are Switching to NexaDeck + NexaLive

The professional karaoke DJ industry has been underserved by technology for far too long. While every other entertainment vertical has modernized, karaoke DJs are still running software designed when Windows XP was cutting-edge.

The DJ Remote Changes Everything

The single biggest shift NexaLive brings to professional karaoke is the Mobile DJ Panel. For the first time, a working KJ can control their entire show from their phone. Play, pause, skip, adjust pitch and tempo, manage the rotation, and handle incoming requests \u2014 all from anywhere in the venue. The cloud relay means it works from any network. Your show keeps running whether you're at the booth or on the dance floor. This isn't a companion app with limited controls. It's full show control, designed to replace the laptop as your primary interface during a performance.

The Audience Has Changed \u2014 Your Software Should Too

Today's karaoke audiences grew up with smartphones. When they walk into a karaoke bar and are handed a paper songbook and a pencil, the experience feels outdated before the first song plays. NexaLive meets your audience on their phones. A QR code scan gives them instant access to your full song catalog, one-tap requests, and real-time queue tracking. No app to download, no account to create.

Audio Quality Is Not Optional

When a singer steps up to the mic, the audio quality reflects directly on you. NexaDeck's Rust-powered audio engine uses SoundTouch DSP to deliver pitch shifting and tempo control that sounds natural and musical. This is the core of the engine, built with the same technology used in professional studio tools.

Your Library Is Your Investment

Professional KJs have invested thousands building CDG and MP4 collections. Streaming-only platforms ask you to abandon that investment. NexaDeck respects your library. Import your existing files, search them instantly, enrich them with MusicBrainz metadata, and detect duplicates with BLAKE3 hashing.
