I took this on one tour and a few one off shows. It's an amazing piece of gear if you are trying to avoid using a laptop for your backing tracks. You get 16 tracks of audio, plus you get a midi track that lines up with your backing tracks to control a drum machine or a synthesizer, etc...it comes with the original power supply

The Cymatic Audio LP-16 is a dedicated, laptop-free 16-track audio and MIDI player designed for live performances. It eliminates the need to run complex DAW software on a computer onstage. Instead, it plays synchronized audio tracks and MIDI data directly from a standard USB drive.It provides a reliable way to route backing tracks, click tracks, and automation cues for musicians, bands, and theatrical setups. Key features and specifications include:Core Playback & Standalone Features16-Track Audio Playback: Plays up to 16 separate mono WAV audio tracks simultaneously at 24-bit resolution (44.1 or 48 kHz).MIDI Sync & Sequencing: Supports standard MIDI file playback fully synchronized to the audio tracks, allowing you to control external hardware synthesizers, samplers, and even DMX lighting rigs.Standalone Operation: Requires no computer to operate during the gig. You simply load files onto a USB hard drive and plug it directly into the front panel.Playlist Management: Using the companion uTool software, you can easily organize songs into setlists, assign specific wave files to specific outputs, and adjust volume settings offline. It also supports on-the-fly setlist modifications.Footswitch Compatibility: A dedicated footswitch input allows for hands-free start, stop, and pause control—ideal for solo performers.Connectivity & Outputs16 Mono Outputs: Features 16 unbalanced 1/4" analog outputs, which give you discrete control to send individual instruments, vocal stems, and clicks directly to a Front-of-House (FOH) or monitor mixer.Headphone Jack: Dedicated headphone output with a volume control for convenient onstage monitoring and cueing.Stereo Line Input: Includes a stereo line-in on the back for connecting auxiliary devices (such as an iPhone or MP3 player), which is great for background music during set breaks or virtual soundchecks.Dual Functionality: USB Audio InterfaceBeyond the stage, the LP-16 doubles as a studio-quality USB audio interface when connected to a computer or iPad.Input/Output: Functions as an 18-output / 2-input interface.Compatibility: Features plug-and-play functionality via Core Audio on Mac, and uses WDM and ASIO drivers on Windows PCs. It is also fully compatible with iOS devices (requires an Apple Camera Connection Kit).
