EZCart is a professional broadcast audio cart machine for Windows and macOS. Native low-latency audio engines, Dante and ST 2110-30 IP audio routing (beta), full MIDI control — everything a control room needs to put audio on the wire in under 5 milliseconds.
Drop audio files onto cart buttons. EZCart decodes to 32-bit float at your target sample rate — 48kHz or 96kHz — and holds the PCM in memory. No disk access on playback. Unlimited carts across unlimited pages per session.
Select Analog, Dante AoIP, or ST 2110-30 as your output mode. Assign each cart to a stereo channel pair on your multi-channel interface — up to 32 stereo pairs simultaneously. EZCart opens the device in exclusive mode — WASAPI on Windows, Core Audio on Mac — and holds it for zero-latency access.
Hit a cart button, press F1–F12, or trigger via MIDI from your console, router, or footswitch. The native real-time audio engine writes audio to the hardware buffer in under 5ms on a dedicated interface. The log captures every fire automatically.
Every feature decision was made with broadcast in mind — IP audio, MIDI, low latency, and session reliability.
Exclusive device access — WASAPI on Windows, Core Audio with adjustable buffer size on Mac — delivers hardware-level latency on dedicated interfaces: RME, MOTU, Dante Virtual Soundcard. No OS mixer, no resampling, no buffering artifacts. Shared mode fallback for consumer devices on Windows.
Select your Dante or AES67 device and EZCart routes audio directly onto your IP network — no converters, no patch bays. Compatible with Dante Virtual Soundcard, Lawo VSC, and any AES67-compliant interface that presents as a Windows or Mac audio device. Per-cart channel pair assignment up to 64ch. Dante and ST 2110-30 support is in beta — test in your environment before going to air.
Per-cart MIDI trigger with configurable note, channel, and velocity. Separate Play and Stop notes. Note On or Note Off trigger mode. Any Channel mode. MIDI out for button-lit controller feedback — fire a cart and light up your console. MIDI Learn on every input field.
4, 6, or 8 column grid. Unlimited cart pages per session. Drag-and-drop reorder within a page. Rundown number filter highlights relevant cues in real time — type a number and the rest dims. F1–F12 and custom hotkeys. Space bar to stop, Ctrl+Z / ⌘Z to undo.
Every fire and stop is timestamped and logged automatically. Export as TXT, CSV, or PDF at any time. Auto-saves on close. Useful for compliance logging, rights reporting, billing by airtime, and post-show review.
Full session state saved to a .ezcart file — cart names, colors, file paths, channel assignments, MIDI mappings, and rundown numbers. Auto-saves to local storage on every change. Load yesterday's show and be on-air in seconds.
Record directly into EZ Cart from any audio input — analog line-in, Dante AoIP, or ST 2110-30 — no separate recorder needed. Assign straight to a cart slot or park it in the sidebar library for later use. Pre-record VU monitoring lets you check levels before you hit record; takes save as 32-bit float WAV to a configurable folder.
Every clip opens in an interactive waveform with draggable in/out trim handles. Zoom from 1× to 16× with the scroll wheel, preview In→Out playback with a live playhead, and set trim points on the fly with the I/O keys while it plays. Trim points save with the session.
Assign any key or key combination to fire a specific cart — not just F1–F12. Click Learn, press the key, done. Custom hotkeys take priority over the default mapping, are scoped per page, and auto-reassign with a warning if a key's already in use elsewhere on that page.
Set carts in a row — or an entire page — to Cut or Crossfade so firing a new one automatically stops or smoothly ramps out whatever's already playing in that group. Crossfade duration is adjustable from 1 to 5 seconds with a true two-sided ramp, both sides fading in perfect sync.
Tag carts with a shared letter (A–H) and firing one fires all of them together — built for multi-language rows, synchronized beds, or any cue that needs to move as a set. Stop any member and the whole gang stops with it.
