Glossary

COSM

COSM stands for Composite Object Sound Modeling. This is Òa technology which combines multiple sound models to create new sounds,Ó which was first used on the RolandÕs VG-8 V-Guitar System. For example, sounds created on the VG-8 are the result of a variety of sound models (elements) such as the pickup, the body of the guitar, the guitar amp, mic, and speaker etc.

When a VS8F-1 effect expansion board is installed, the VS- 880 will be able to apply effects using COSM (such as guitar amp simulation) without the need for any other equipment. (p.46)

MTC

MTC stands for MIDI Time Code. This is a group of mes- sages which are transmitted and received between MIDI devices to synchronize their operation. Unlike MIDI Clock messages, MTC specifies an absolute time. Like SMPTE time code, MTC also supports a variety of frame rates. If you wish to use MTC to synchronize the operation of two devices, both devices must be set to the same frame rate. (p.86)

RSS

RSS stands for Roland Sound System. This is an effect which allows a sound source to be placed in three-dimen- sional space when played back on a conventional stereo sys- tem. The sound can be placed not only in front of the listen- er, but also directly to the side, above, below, and behind the listener. (VS8F-1 OwnerÕs manual p.33)

S/P DIF

S/P DIF stands for Sony/Philips Digital Interface Format. This is a specifications for transmitting and receiving stereo digital audio signals between digital audio devices. The VS- 880 provides coaxial connectors which support S/P DIF. (p.72)

SMPTE time code

This is a signal format defined by the American organization SMPTE (Society of Motion Picture and Television Engineers) which is used to synchronize the operation of video or audio devices. SMPTE specifies Òhours:minutes:seconds:framesÓ to indicate the address of each frame of a video image. For this reason, there are a variety of frame rates.

Auto mix

This is data which records INPUT➝TRACK, INPUT MIX, TRACK MIX and Master block settings of the mixer. Mixer settings for a specific time location are referred to as a Snapshot. Data which records time-variant changes in mixer settings such as fade-in or fade-out is referred to as Realtime data.

Scene

This is data which records INPUT➝TRACK, INPUT MIX, TRACK MIX and Master block mixer settings and effect set- tings for a specific moment in time. Even after mixing oper- ations have been performed repeatedly, a Scene can be recalled to instantly restore the settings for fader, pan and effect algorithm etc. that were in use when the Scene was stored. (p.51)

Sync track

This is a track provided separately from the audio recording track, for the purpose of recording MIDI Clock data. The Sync track records the MIDI Clock messages that are trans- mitted from a MIDI sequencer etc. By transmitting these MIDI Clock messages back to the MIDI sequencer, it will be possible to synchronize even to a song that contains com- plex tempo changes. In this case, the VS-880 will be the mas- ter and the MIDI sequencer will be the slave. (p.91)

Scrub

This is an editing technique in which a very short section of audio is played back repeatedly while you move the current time location, similar to the result of manually moving a reel of analog tape while it remains in contact with the playback head. This is a convenient way to ÒcueÓ a desired location in the recording. Since the playback pitch and formats will not change, cueing is possible with substantial accuracy. (p.77)

Tempo map

Data describing the songÕs measures, beats and tempo. By transmitting this data to a MIDI sequencer etc., synchro- nized operation with an external MIDI device is possible. (p.89)

Vari-pitch

When a song is played back on the VS-880, this function allows the playback speed of the song can be adjusted in order to match the pitch with instruments whose tuning is not easily changed.
