Appendix Glossary A Auto Accompaniment (Style playback) A function that generates pre-programmed rhythm, bass and chord backing in response to specific notes/chords played (or received via MIDI). C Chorus One of the Effect types. Depending on the particular chorus type and parameters, this can make a voice sound "larger," as if several identical instruments were playing in unison, or it can give a voice greater warmth and depth. Clock [1] A unit of note resolution for MIDI Sequence data. The sequencer determines the playback position of the Song or Pattern (MIDI sequence data) by using the following three parameters: Measure, Beat, and Clock. [2] Also referred to as "MIDI Clock," defined as System Realtime Message in MIDI. This message is transmitted with a fixed interval (24 times per 1/4 note) to synchronize connected MIDI instruments. On MIDI Sequencers, you can select whether the instrument's internal clock will be used as the Timing Clock, or external Timing Clock messages received via MIDI IN will be used. Control Change A set of MIDI Channel messages that allow for control of a wide variety of sound parameters, including modulation, pan, volume, expression, brightness, effect depth, and others. These can be adjusted using physical controllers, such as the Modulation Wheel and the Foot Controller. D Depth Refers to the amount or degree to which a parameter setting changes the original sound. E Effect On the TYROS, an "Effect" is a processing block that alters the sound output from the tone generator block of the instrument, using DSP (Digital Signal Processing) circuitry to change the sound in various ways. The TYROS provides two types of effects: the DSP effects described above (such as Reverb, Chorus, DSP and DSP variation) and other effects (such as Harmony/Echo , Initial Touch, Sustain, and Poly/ Mono). 166 TYROS Owner's Manual Event List A useful Song/Style/Multi Pad Creator tool that arranges all events in a song in chronological order (in measures, beats, clocks), and allows you to make detailed changes to those events. F Factory Reset Refers to the original, factory-programmed settings of User drive memory, loaded to the instrument before it is shipped. Flash ROM ROM that can be overwritten allowing you to store your own original data, unlike conventional ROM. G Gate Time In sequence recording, this determines the actual length of time a note sounds. When entering the note events in Step Recording of the MIDI sequencer, Gate time is determined as a percent value of the step time. A setting of approximately 50% produces a staccato sound, values between about 80% and 90% produce normal note length, and a value of 100% will produce a slur. L Left-hand section of the keyboard The section of keys to the left of the split point. Besides being used to play the LEFT voice, they can also be used to indicate/ play chords for style playback as well as the Harmony and Vocal Harmony effects. LFO An abbreviation for low frequency oscillator, which generates a low frequency signal on the tone generator block. The signal from the LFO can be used to modulate the pitch, filter, and amplitude. Modulating the pitch produces a vibrato effect, modulating the filter produces a wah effect, and modulating the amplitude produces a tremolo effect. Lower A keyboard part played on the left side of the keyboard from the split point for the voices instead of LEFT. This part is not affected by the on/off status of the [ACMP] button. N Note On/Off MIDI messages which represent notes played on a keyboard or other instrument. Pressing a key produces a Note On message, and a Note Off message is produced when the key is released. Note On message includes a specific note number which corresponds to the key which is pressed, plus a velocity value based on how hard the key is struck. 164
