Фрагмент инструкции
Increasing this will increase the number of times thata delay is repeated, or will make a chorus effect sound richer. However if the feedback level is increased excessively, oscillation can occur, and unwanted sounds can be generated. Filter A device or function that cuts a portion of the frequency bandwidth to modify the tone. There are various types of filter, such as the Low Pass Filter which passes only the portion that is lower than a specified frequency (the cutoff frequency), or the High Pass Filter which passes only the portion that is higher. Some filters are able to vary the cutoff frequency over time according to a pre-determined pattern. Flanger An effect that produces a metallic modulation that resembles the sound of a jet plane taking off and landing. It is produced in a way similar to delay or chorus effects, by adding a slightly time-delayed sound to the input. Flash memory A type of memory that can maintain its data without a backup power source such as a battery. Its data can be electrically rewritten from outside. Flash memory is suitable for storing various types of data that must be maintained even when the power is off, or for containing the system software of a device. Since the data can be rewritten electrically, it is easy to update the system software of a device. However since it normally operates as ROM (read-only memory), it is not suitable for applications that require the contents to be erased or rewritten at high speed. In this system, flash memory is used in the area that holds the system software and the libraries. Flash memory is also used in the memory cards (SmartMedia) that are used for external backup etc. -» SmartMedia 236 Glossary Flex bus A general purpose bus, of which twelve are provided for each processor. These can be used for a wide variety of purposes, such as collecting signals to be sent to the internal effects, or for providing separate stage monitor feeds. Flex buses 1-8 differ slightly in functionality from 9-12 (refer to the diagram on p. 29). The VM-7200 processor provides independent outputs (bus out) for flex buses 5-12. -> Bus Foot sw, Foot switch A switch that is operated by stepping on it. These can be used to turn various functions on/off or to start/stop a device when both hands are occupied in playing a musical instrument etc. The FOOT SW jack of this system (located on the rear panel of the console) allows up to two Boss FS-5U switches or one Roland DP-2 (pedal switch) to be connected. If you wish to connect two FS-5U switches, use a PCS-31 splitter cable. Pedal sw Formant A fixed frequency region of emphasis that is determined by the size of the vocal cords, and which determines the character of a human voice. When a recorded voice is simply lowered in pitch, the location of the formants is also changed. (For example when the pitch is raised, the resulting "duck voice" sounds as though the singer has smaller vocal cords. Lowering the pitch produces a "giant voice" that sounds as though the singer has larger vocal cords.) This system provides a Voice Transformer effect algorithm that allows the fundamental pitch and the formants to be adjusted separately, allowing a variety of vocal characters to be produced. Format When used as a verb, "format" refers to the act of re-writing the data storage divisions on a magnetic disk or memory card etc. so that it conforms to the storage methods used by a particular device. On this system, a newly purchased memory card or one that has been used by a different device must be formatted by this system before it can be used. When a storage medium is formatted, any data previously existing on that medium will normally be lost. When used as a noun, "format" refers to a set of conventions by which data is stored or organized, such as "Windows format." Frame This refers to the individual still images that make up a moving picture on a video recorder etc. In the context of SMPTE time code or MTC, a "frame" is a unit of time. The frame rate selection determines whether a frame corresponds to 1 /30th or l/24th of a second. -> Frame rate -* SMPTE time code -» MIDI time code Frame rate The number of frames per second in SMPTE time code etc. Also refers to the type of time code indicated thereby. The frame rate can be 30, 39.97N (non-drop), 29.97D (drop), 25, or 24 per second. SMPTE time code Frame Non-drop format Frequency The number of times in one second that a signal oscillates, expressed in units of a Hz (Hertz). The pitch of a sound is also expressed as a frequency. Frequency-independent compressor An effect that divides the signal into low, mid, and high frequency bands, and separately applies appropriate compression to each band. Gate reverb A method for cutting the reverb during its decay. Also, an effects processor for doing this. In the 80's, it was often applied to bass drum or snare drum sounds to accentuate the beat. Generator A device that produces a signal. On this system...
