I am selling this item because I purchased it in September of this year but haven't had much time to use it, so it's hardly been used. As mentioned above, I haven't used it at all after using it a few times, so there are no scratches or stains on the main unit. All the included accessories are shown in the photos. Thank you for your consideration.

The SP-404MKII is the ultimate sampler, born through community feedback and extensive research and development. Featuring a vibrant OLED display, expressive new pads, newly added effects, a highly operable sequencing and sampling workflow, and a sound library that inspires instant song creation, it delivers unprecedented speed and superior performance. • Maximum Polyphony 32 voices ● Storable Data Samples = 2,560 (16 samples x 10 banks x 16 projects: recorded in internal storage) Patterns = 2,560 (16 patterns x 10 banks x 16 projects: recorded in internal storage) ● Internal Storage Size: 16GB * Includes preloaded data ● Maximum Sampling Time 16 minutes (approximately 185MB per sample) ● Skip Back Sampling Time Up to 25 seconds (records LINE OUT signal continuously, separately from sampling/resampling) ● Internal Data Format 16-bit linear ● Import Format WAV / AIFF / MP3 * SP-404MK2 APP MAR, WAV / AIFF / MP3 / FLAC / M4A compatible
