MC505s

The MC505s, also known as the Roland Groovebox MC-505, is a digital music workstation and groovebox that was released by Roland in 1999. It combines a synthesizer, sequencer, drum machine, and effects processor into a single unit, designed for live performance and music production. The MC-505 features a keyboardless design, relying on pads and knobs for input and control. It is equipped with Roland's SR-JV expansion board system, allowing for the addition of further sound sets.

The MC-505's sequencer can record and play back MIDI data, enabling users to create complex song arrangements. Its synthesizer engine offers a wide range of sounds, from synthesized basses and leads to realistic instrument emulations. The built-in drum machine provides a variety of drum kits and percussion sounds. Effects processors include reverb, delay, chorus, and distortion, which can be applied to individual sounds or the overall mix.

A key feature of the MC-505 is its "performance control" section, which allows for real-time manipulation of sounds and patterns. This includes dedicated knobs for filter cutoff, resonance, envelope, and LFO, as well as buttons for triggering arpeggios and pattern variations. The unit also includes a joystick for expressive control over pitch and modulation. The MC-505 gained popularity among electronic musicians and DJs for its versatility and hands-on approach to music creation. It is considered a classic piece of gear in the electronic music community.
