The back of the 12 Step has several connectors: a 1/8" expression pedal input, a USB port for connecting to the optional MIDI expander unit, and a USB port for connecting to a computer or hardware electronic device (synth module, sequencer, etc.). Each key has a little red LED light that illuminates when the key is pressed, which helps the ...
A Roland keytar, keyboard MIDI controller designed to be worn with a shoulder strap during performance.The keytar does not produce any musical sounds by itself.

Roland GS, or just GS, sometimes expanded as General Standard [1] [2] or General Sound, [1] is a MIDI specification. It requires that all GS-compatible equipment must meet a certain set of features and it documents interpretations of some MIDI commands and bytes sequences, thus defining instrument tones, controllers for sound effects, etc.
A port expander is a device that allows one port on a computer system to connect to multiple devices. Two basic forms of port expander exist: internal and external. An internal expander has a connection inside the computer, typically on the motherboard, and the only part the user sees is the expansion plate containing multiple ports.
If a MIDI file is programmed to the General MIDI protocol, then the results are predictable, but timbre and sound fidelity may vary depending on the quality of the GM synthesizer. The General MIDI standard includes 47 percussive sounds, using note numbers 35-81 (of the possible 128 numbers from 0–127), as follows: [ 3 ]
General MIDI Level 2 or GM2 is a specification for synthesizers which defines several requirements beyond the more abstract MIDI standard and is based on General MIDI, GS extensions, and XG extensions.
