NexaDeck — Professional Karaoke Show Control

NexaDeck is where the show happens. A professional-grade desktop application built from the ground up for karaoke DJs who demand reliability, audio quality, and workflow efficiency. Powered by a custom Rust audio engine, NexaDeck handles CDG+MP3 lyrics, MP4 video karaoke, and audio-only tracks with professional DSP that legacy karaoke software simply cannot match.

• Rust-Powered Audio: Independent pitch shift (±12 semitones) and tempo control (0.5x–2.0x) with SoundTouch DSP — the same engine used in studio tools like Audacity
• Smart Singer Rotation: Drag-and-drop queue management with away status, duplicate prevention, and configurable insertion strategies
• Multi-Display Output: Dedicated DJ view and audience screen with synchronized CDG lyrics, scrolling singer marquee, and custom branding
• Library Intelligence: Smart search across 10,000+ songs with instant results, MusicBrainz enrichment, and BLAKE3 duplicate detection
• Buffer Music System: Automatic background music between performances with drag-and-drop queue management
• Offline-First: Your show runs on your hardware, your library, your terms. Cloud features enhance — they never gate

NexaLive — Cloud-Powered Audience Engagement

NexaLive connects your audience to your show in real time. Patrons scan a QR code, browse your songbook, and submit song requests from their phone — no app download, no account creation, no friction. DJs get a cloud-based show management dashboard, real-time request queue, and a mobile DJ panel that works from anywhere in the world.

• Zero-Friction Requests: Audience requests songs in 30 seconds. Scan, search, tap. No app. No account. Just music.
• Your Library, Cloud-Searchable: Full-text search with genre filtering, version badges, and rich metadata. Sync your catalog from NexaDeck in minutes.

• Venue Kiosk Mode: Turn any tablet into a song request station with PIN-protected exit and auto-reset between patrons
• Show Discovery: Every DJ gets a branded landing page with live show status, upcoming schedule, and browsable songbook
• Real-Time Updates: Patrons see live queue position and wait time estimates. WebSocket-powered — no page refreshing needed.

Audience Scans QR Code

A patron scans the QR code on a table card, TV screen, or social media post. No app download required — NexaLive runs in any browser.

Browse & Request Songs

They search your entire song library by title, artist, or genre. Tap a song, enter a display name, and submit — done in 30 seconds.

Request Arrives on NexaDeck

The request flows through NexaLive's cloud to NexaDeck on the DJ's laptop. Automatic library matching scores each request against your local catalog.

DJ Accepts & Queues

Accept with one tap. The song is added to the singer rotation. The patron sees their queue position and estimated wait time update in real time.

Singer Performs

NexaDeck plays the track with CDG lyrics on the audience screen, professional audio DSP, and all the show management features the DJ needs.

DJ Controls From Anywhere

The DJ can manage the entire show from their phone via the NexaLive Mobile DJ Panel — play, pause, skip, rotate, handle new requests — from any network.

Professional Karaoke DJs

You run 3–7 shows a week at bars and venues. You need reliable software that handles large catalogs, fair rotation, and audience engagement without adding complexity. NexaDeck replaces your aging show control software while NexaLive modernizes audience interaction with digital requests, live queue tracking, and a mobile DJ panel.

• Replace paper slips with zero-friction digital requests
• Control your show from the dance floor, not just the laptop
• Import and search your entire CDG/MP4 library instantly
• Professional pitch and tempo control for every singer

Bars & Venues

You want a modern, tech-forward karaoke experience that impresses your patrons and keeps them coming back. NexaLive's kiosk mode turns a tablet into a request station. Your branded hub page promotes shows online. QR code requests mean every phone at the bar is a song request terminal.

• Kiosk mode on venue tablets with PIN-protected exit
• Branded DJ landing pages to promote karaoke nights
• QR codes on table cards and screens for instant access
• Real-time queue display keeps patrons engaged

Mobile Entertainment Companies

You run karaoke at private events, corporate functions, and parties across different locations. You need portable, reliable software that works anywhere and impresses clients. NexaDeck's offline-first design means the show runs even in basements with no WiFi, while NexaLive adds modern audience engagement when connectivity is available.

• Offline-first: shows run on your hardware, no internet needed
• Cross-platform: bring your Mac, Windows, or Linux machine
• Professional audio DSP impresses corporate clients
• Cloud features activate when WiFi is available

Only Integrated Desktop + Cloud

No competitor offers both professional desktop show control AND a cloud audience engagement platform in one connected system. DJs using competing software must cobble together third-party tools that never truly integrate.

Zero-Friction Audience Experience

Every competing request system requires an app download, account creation, or complex interface. NexaLive is scan-search-tap — your audience requests songs in 30 seconds with no downloads and no signups.

DJ Liberation — Control From Anywhere

No competing karaoke software offers cloud-based mobile control. DJs are physically tethered to their laptops. NexaLive's DJ Panel works from any phone, on any network, anywhere in the world.

Professional Audio That Competitors Can't Match

NexaDeck's Rust-powered audio engine delivers independent pitch and tempo control, rubberband mode, and turntable mode. Most competitors offer basic key change at best. Browser-based platforms can't match native performance.

Offline-First, Cloud-Enhanced

Streaming platforms fail when the internet drops. NexaDeck never depends on connectivity for core show operations. Cloud features enhance the experience — they never gate it. Your show runs on your hardware.

Respects Your Existing Library

Professional KJs have invested thousands building CDG and MP4 collections. Streaming platforms force you to abandon that investment. NexaDeck supports your existing files while adding smart search, metadata enrichment, and cloud sync.

Cross-Platform From Day One

PCDJ Karaoki, Karma, and CompuHost are Windows-only. NexaDeck runs on Mac, Windows, and Linux — meeting DJs where they are rather than dictating their hardware choice.

Modern Show Discovery

No competing platform gives DJs a branded web presence with live show status, upcoming schedules, and a browsable songbook. NexaLive turns every DJ into a discoverable destination.
