MC4000

The MC4000 is a model of portable electronic keyboard manufactured by Roland Corporation. It was introduced in the late 1980s and targeted at home users and hobbyists seeking a versatile and affordable instrument. The MC4000 features a 61-key velocity-sensitive keyboard, providing a dynamic playing experience. It incorporates a variety of built-in sounds, including pianos, organs, strings, and synthesized timbres, along with a selection of rhythm patterns for accompaniment.

A key feature of the MC4000 is its onboard sequencer, allowing users to record and play back multi-track musical arrangements. This capability made it a popular choice for aspiring composers and musicians who wanted to experiment with creating their own songs without external hardware. The keyboard also includes effects such as chorus and reverb to enhance the sound. Connectivity options typically comprise MIDI in/out ports, enabling integration with other MIDI-compatible devices like sequencers or sound modules, and audio outputs for connecting to amplifiers or recording equipment. The MC4000 is powered by an AC adapter or batteries, contributing to its portability. While it represents a product from an earlier era of digital keyboards, the MC4000 remains a recognizable instrument for those familiar with Roland's home keyboard lines from the late 20th century.
