ACC
  Short for "accompaniment", i.e. one or several parts played by the Arranger.
Aftertouch
  A realtime control produced by pushing a key down further than the point at which the key's note sounds. Channel aftertouch affects all currently sounding notes; polyphonic aftertouch affects only the pressed note.
AIFF
  For "Apple Audio Interchange File Format." A commonly used type of disk file that contains audio, developed by Apple. Also called ".aif" files. The VA-7 and VA-76 can import such files and turn them into VariPhrases.
Ambience
  The resonating of the real or imaginary space in which a sound occurs.
Amplitude
  The technical term for a signal's volume or loudness.
Arpeggiator
  A device that plays a pre-programmed series of notes. An arpeggio can be any kind of musical phrase, including simulations of guitar strumming.
Arranger
  On a Roland keyboard, this term refers to a special, interactive sequencer that provides automatic accompaniments based on the chords you specify. The Arranger can play several kinds of accompaniments, which are called "Music Styles". Each Music Style consists of several pattern (divisions) that play an introduction, transitions, main accompaniment patterns, or an ending.
Attack
  A parameter that sets the speed at which an envelope or dynamics processor starts. With an envelope, Attack sets the speed at which the enveloped setting travels from 0 to its nominal value. In a dynamics processor, it sets the speed at which the processor starts working.
Auto Punch
  A feature on recording devices that automatically starts and stops recording for you when you're punching at locations you've set beforehand.




Back up
  To make a copy of data and to store the copy on an external medium -- such as a FD, ZIP disk, or CD-R disk -- for safekeeping. This copy is called a "backup." Backing up is extremely important to safeguard against unexpected events. To play or work on a song or project that's been backed up, it must be "recovered."
Balanced
  A type of audio connection that uses the three leads in a cable, connector and jack as part of a phase-cancellation scheme to boost signal and reduce noise.
Band Orchestrator
  A function for varying the accompaniment patterns by leaving out certain parts (or adding more parts) to the selected division. Such changes are usually preset by Roland.
Bank
  In MIDI instruments, a group of patches. Each bank can contain up to 128 patches (or sounds), numbered from 0-127 or 1-128.
Bank Select
  A type of MIDI message that typically corresponds to a specific bank of patches. When an instrument receives a Bank Select message, the corresponding patch bank is selected. Typically, a Bank Select message is followed by a Program Change message that selects a patch within the bank. A Bank Select message may contain two components, an MSB ("Most Significant Byte") and/or an LSB ("Least Significant Byte") value.
Bass
  The lower frequency range of a sound, usually from about 200 Hz down.
Bass Inversion
  See "Leading Bass".
Bend range
  The maximum pitch change that can be applied by moving a pitch bend control.
Break Mute
  A function that allows you to temporarily stop the Arranger until the next downbeat, (which is called a "break"). The most famous song where this is used is called "Great Balls of Fire".
Bulk dump
  The transmission of settings from one MIDI device to another (using SysEx data). Such data can also be transmitted to devices that do not understand them, but can save them (sequencers, data filers, workstations).
Burn
  Burn is music industry slang for writing data onto a CD.

  The term used in the owner's manuals for the keys on the front panels that are used to select and set parameters/functions.




CC number (Control Change Number)
  A numbered MIDI message that is often assigned to a particular parameter (CC01= modulation, CC07= volume). A MIDI Control Change number is followed by a value that sets the parameter in the MIDI device that receives it.
Chord recognition area
  The range of notes or keys that are scanned by the Arranger to decide in what key the selected Music Style should sound. This is a real-time process: whenever you play different notes in the chord recognition area, the key of the currently selected Music Style division changes instantly.
Chorus
  An effect in which multiple copies of a signal are played together slightly out of time to create a shimmering effect.
Coarse tune
  The adjustment of pitch in semitone steps.
Compressor
  A dynamics processor that reduces the level of any signal exceeding a specified threshold volume.

Cover
  A set of settings on a Roland keyboard that change the sounds and effects of a Standard MIDI File or Music Style at the touch of a button (called "Stylist" on the E-200 and E-100).
CPT
  "Clock pulse time". Refers to the subdivisions of a bar on a MIDI sequencer (i.e. all four beats of a 4/4 measure).
Cutoff
  The frequency at which a filter starts to work.




D-Beam

General MIDI
  General MIDI -- or "GM" -- is a music industry standard ratified in 1991. It established a set of 128 synth, orchestral and percussion sounds so that GM files and Standard MIDI Files play back on any GM-compatible instrument with predictable results.
General MIDI 2
  General MIDI 2 -- or "GM2" -- is an update to the General MIDI standard. It was ratified in 1991. GM2 was adopted by Roland and Yamaha to extend the set of GM sounds, expressive musical parameters and other features in order to provide for more consistent playback of GM2-compliant files on different instruments.
GM, GM2
  Abbreviation for "General MIDI" and "General MIDI 2," respectively.
GS
  Roland's extension of General MIDI. GS adds features such as chorus, reverb and panning for more realistic sound, and expands beyond the original 128 sounds of General MIDI to 16,000-plus sounds. This open-ended convention has been licensed by Apple for QuickTime 3.0, 4.0 & 5.0, by Microsoft for their GS synthesizer, and by Nintendo for their sound applications.

LFO ("Low Frequency Oscillator")
  An inaudible low-frequency waveform that alters a basic setting -- a waveform's pitch, a tone's filter or panning settings -- in a cyclic manner according to the shape of the LFO's waveform. An LFO is typically used as a means of adding vibrato, tremolo or auto-panning.
Limiter
  A compressor set to a ratio of 10:1 or greater. This has the effect of preventing all but the fastest signals from exceeding the threshold volume, thus forcing them into the desired level range.
Line level
  The high-level signal produced at the outputs of audio equipment such as synths, samplers, beatboxes, turntable preamps, CD players, mixers, recorders and playback devices.
Local
  A MIDI parameter that allows you to establish (On) or break (Off) the connection between an instrument's keyboard/arranger/sequencer and its internal sound source. This is possible, because everything you do on a keyboard (press keys, use the Bender/Modulation functionality, press a footswitch, etc.) is translated into MIDI messages, which are then transmitted to the internal tone generator (if Local is on) AND the MIDI OUT socket, or ONLY to the MIDI OUT socket (if Local is off).
Loop
  As a verb, the act of playing the same section over and over. As a noun, a chunk of audio that's played over and over. Also an effect routing that adds an effect to a signal by sending a copy of the signal to an effect, and mixing the effect's output with the original signal.
Lower
  One part you can play in realtime. If the keyboard is split, this part is assigned to the left half.

Minus One
  A function that allows you to switch off sequencer parts you want to play yourself. On most arranger keyboards, only one part can be muted in that way (hence the name). Other models allow you to switch off several parts. Some keyboards provide a special Link function that changes the Tone settings of the part you play based on the information stored for the track you muted. That way, changes to the sound can be automated.

NTA
  Short for "Note-to-Arranger". This refers to the chord information the Arranger uses to decide in what key the selected Music Style should be played back. Roland arranger keyboards can receive such note messages from an external MIDI instrument, which has the same effect as pressing the corresponding keys in the note recognition area of the keyboard. Most Roland arranger keyboards do not transmit these NTA notes: they transmit the result of those notes (i.e. the Music Styles note messages played in the correct key).
