Glossary 109
MIDI—An acronym for Musical Instrument Digital Interface. An internationally agreed stan- dard that allows electronic musical instruments and audio equipment to communicate.
MIDI Clock—A clock signal transmitted as MIDI data. MIDI Clock refers to a timing signal and Start, Continue, and Stop commands. The MD4S can supply MIDI Clock to a MIDI sequencer for synchronized operation.
MIDI Song Position Pointer—A type of MIDI message that is used to derive position information from a MIDI Clock signal. The MD4S generates MIDI Song Position Pointers. So no matter where you start playback in a song, your MIDI sequencer will locate to that point and then play along in synchronization.
MIDI Timecode (MTC)—An addition to the MIDI Standard that allows audio equipment to be synchronized. MIDI Timecode contains clock and position information. MD4S can sup- ply MTC to a MIDI sequencer for synchronized operation.
MiniDisc—A compact data storage medium designed to store music. MiniDiscs come in two varieties: playback only and recordable. MiniDiscs can only be used for 2-track or mono recording with the MD4S. MiniDiscs recorded on the MD4S can be played on a normal Mini- Disc deck. See also Random Access, ATRAC, and MD DATA Disc.
Mixdown—“Mixdown” (also called “track-down”) is the process of mixing two or more pre- viously-recorded tracks into a stereo mix, and recording the result on an external master recorder.
Monitor CUE—The cue monitor allows you to monitor individual tracks as they are being recorded or played back. In Record Pause mode and during recording, the CUE monitor source is the signal being recorded (i.e., the input signal). For playback the CUE monitor source is from disc (i.e., the signal that was recorded to disc). This is useful with the punch in/ out functions, because you can monitor the recorded signal up to the specified IN point, and then the new signal that’s being recorded up to the OUT point.
Overdub Recording—“Overdubbing” is the process of recording a new performance while monitoring other previously-recorded tracks.
Panning—A technique used to position sounds in a stereo mix.
PB—An abbreviation for Playback. This abbreviation appears next to the input selector switch on each input channel and is used to select the disc signal as the source for the input channel.
Phone Jack—A 1/4-inch socket commonly used on audio equipment.
Phono Jack—Also know as an RCA jack, this type of connector is often used on semiprofes- sional audio and video equipment.
Ping-Pong—“Ping-pong” recording is the process of mixing two or more previously- recorded tracks, and re-recording the mix to one or two other tracks.
Pre-RollTime—For Auto Punch In/Out, this is the time before the IN point at which play- back starts. See “Setting the pre-roll/post-roll times” on page 55 for more information.
Post Fader—A point in the signal path after a fader. The signals for the MD4S AUX controls are sourced post-fader. So as well as turn up the AUX control, you must also raise the fader. This has the advantage that the level of the processed signal from the external effects processor depends on the level of the unprocessed signal that is controlled by the fader.
Post-RollTime—For Auto Punch In/Out, this is the time after the OUT point at which play- back stops. See “Setting the pre-roll/post-roll times” on page 55 for more information.
Punch In/Out—A recording technique that allows you to rerecord specific sections of an existing track. The MD4S provides both manual and automatic punch in/out operations.
Random Access—The ability to access data instantly. The MD4S quick locate functions allow you to locate any point instantly. Tape-based recorders do not have random access capa- bilities because they have to wind a tape, which takes time.
