    "summary": "Polyend Tracker Standalone Audio Workstation - Black. Polyend. Tracker Standalone Audio Workstation. Keyboards and Synths. Keyboards and Synths \/ Grooveboxes. available from reverb. price range 300-783.04 USD. condition Excellent. A genuinely unique piece of hardware that bridges old-school tracker workflow with modern sound design capability. The Polyend Tracker is built around a bright 7-inch color screen, a large aluminium data encoder, and a full complement of navigation and function buttons -- all in excellent condition with no visible wear. At its core this is an 8-track hardware sampler and sequencer built around the classic tracker workflow, with patterns up to 128 steps each and the ability to hold note, instrument, and two FX parameter locks per step. Over 20 FX types can be applied per track, and up to 48 instruments can be loaded per project. Sound design goes deep. There are seven sample playback modes: one-shot, forward loop, backward loop, ping pong, slice, wavetable, and granular synthesizer. Samples are recorded at 16-bit\/44.1kHz quality via mic or line input, or loaded from the SD card slot. The granular engine chops samples into small looping windows, with LFO- or envelope-controlled playback position, turning almost any sample into a pad-like drone. The built-in wavetable engine is compatible with popular standards, including Serum and WaveEdit. A full chain of sound-shaping tools is on board: volume, tuning, panning, resonant filters, delay and reverb sends, ADSRs, LFOs, and overdrive. The sequencer also features automatic fill, randomizer, probability, selection rendering, effects per step, live recording, batch parameter editing, micro-tuning, micro-timing, and rolls. The Tracker is slim and USB-powered, and can run off a battery pack for a fully portable production experience. It exports both pattern and song stems directly to the SD card, making it easy to route your work into a DAW. The included MicroSD card ships with demo projects from artists including The Flashbulb, Richard Devine, and Machinedrum, and the device supports MicroSD cards up to 64GB. MOD file compatibility is also included for importing classic tracker projects. This unit is in excellent condition - fully functional, no scratches or damage to the screen, encoder, or pads.
