    Mixdown Monitoring The MT4X offers you a great deal of flexibility in monitoring the status of your recordings. You can monitor the individual channel groups, the stereo bus, the cue bus, or any combination. You control monitoring with the MONITOR SELECT keys GROUP The GROUP keys allow you to monitor the group bus signals.
  • Page 18: Initial Recording16

    The first step in multitrack recording is to record the initial tracks. Usually, these are your rhythm tracks: bassguitar, rhythm guitar, and drums. Note: Before you record anything, you must connect the MT4X to both an input source and a monitoring system. See "Example System" on page 14.
  • Page 19 Therefore, you should set the recording levels to the highest level before distortion sets in. The MT4X is equipped with sensitive peak-hold level meters ( individual tracks and the stereo bus. Use the level meters in conjunction with the monitoring modes (see "Monitoring"...
  • Page 20 • When dbx™ is off, adjust the gain control so that the +3 dB segment occasionally illuminates. • When dbx™ is on, adjust the gain control so that the +9 dB segment occasionally illuminates. Note: The MT4X can recall and display the maximum recording levels obtained during a session. See "Recording Levels Function" on page 42.
  • Page 21: Overdubbing19

    Note: Connecting an instrument with a high output impedance such as an electric guitar or bassguitar to the MT4X may increase noise and distortion. If this happens, connect a direct box or effect unit between the instrument and the MT4X to reduce the impedance.
  • Page 22 The indicator above the key lights and any flashing REC SELECT - TRACK indicators will be illuminated. Press the PLAY key. The indicator above the key lights and the MT4X starts the tape. Play the part again. Note: To prevent wow and flutter effects, do not accidentally adjust the PITCH control while you are recording.
  • Page 23: Punch-In/Out Recording21

    You play your part while punching in and out to start and stop the recorder. For the greatest precision, you should use the advanced automatic punch-in/out features of the MT4X. However, it is reasonably easy to punch-in manually. If you have a footswitch, you can also punch in and out using your foot.
  • Page 24 The REC SELECT - TRACK indicator on the display will flash. TAPE Note: You can skip step 2 at this point. However, you must select a track before you perform the actual recording. Set the working points: AUTO PUNCH Blank space START Pre-roll Punch-in...

TAPE AUTO PUNCH START Note: The AUTO PUNCH indicator will either be flashing or illuminated while the automatic punch-in/ out function is active. Press the PLAY key (or step on the footswitch) to play the tape. The START indicator will light and the IN indicator will begin flashing.
  • Page 26 Rehearsal The MT4X automatically enters rehearsal mode after you have assigned the punch-in and punch-out points. This mode allows you to practice the punch-in/out operation before you actually commit anything to tape. Note: In this mode, you can press the REPEAT key ( perform rehearsal playback between the pre-roll point and the post-roll point.
  • Page 27 Check the recording Press the PLAY key again to play back the tape. The MT4X will automatically play from the pre-roll point to the post-roll point. If the resulting recording is good, press the AUTO PUNCH I/O key to cancel the automatic punch-in/out function.
  • Page 28: Status Indicators

    Status indicators During the operation of the automatic punch-in/out function, you can determine the status by checking the indicators shown in the following table: Function Mark the pre-roll point (see step 3). Start the tape playing (see step 4). If you press the AUTO PUNCH I/O key while the tape is playing, the operation starts here.

  • Page 33 Recording Functions This technique is a combination of overdubbing (see "Overdub recording" on page 15) and ping-pong recording. Connect the input source for the overdubbing channel to its corresponding MIC/LINE INPUT connector. Set the input select key to the MIC/LINE position. Rotate the GAIN control to adjust the level of the input signal.

    ) into the input connector on the effect unit. Plug the output from the effect unit into the AUX RETURN connectors ( Note: If the effect unit has stereo outputs, connect it to the MT4X in stereo. Otherwise, plug it into the L/MONO connector.
  • Page 35 Insert a tape into the master recorder. Start recording on the master recorder. Press the PLAY key on the MT4X to start playback. Note: You may want to remove any count-ins before you create your master tape. There are several ways of doing this.
  • Page 36: Synchronization

    Some MIDI sequencers and rhythm machines are already equipped with a SYNC OUT connector. You can plug this type of machine directly into the MT4X to record FSK onto one of the tracks. If your MIDI sequencer or rhythm machine is not equipped with a SYNC OUT connector, you may need a MIDI/FSK converter such as the Yamaha YMC10.
  • Page 37: Fsk Recording35

    FSK recording Record FSK signals on track 4 The MT4X is equipped with a dbx™ noise reduction system. For recording normal audio signals, the noise reduction system is beneficial. However, dbx™ interferes with the recording of FSK signals. This sometimes results in an unusable sync track. Therefore, the MT4X is also equipped with a SYNC key.
  • Page 38: Synchronized Playback36

    Overdubbing with a synchronized performance If your MIDI sequencer or rhythm machine cannot accept FSK signals, you may need a MIDI/FSK converter such as the Yamaha YMC10. You need to plug the MIDI/FSK converter in between the MT4X and your MIDI instrument.
  • Page 39 Set the connected MIDI instrument to FSK sync mode, to receive the FSK signals from the MT4X. Set any other connected MIDI instruments to MIDI clock mode to slave to the MIDI device receiving the FSK signals.
  • Page 40 The MIDI instrument(s) will playback in sync with the data recorded on track 4. Note: If the MIDI instrument does not play correctly, you probably started the tape at a point after the FSK signal began. You must ensure the tape plays back from before the start of the FSK track. Play the overdub part along with the MIDI instrument(s) and the previously recorded tracks.
  • Page 41: Synchronized Mixdown39

    Master Recorder Mixing Console Tip: A special feature of the MT4X is its TAPE OUT connectors. These allow you to send the track signals directly from the recorder to your external mixer. Connections and setup Plug a compatible cable from the TAPE OUT - SYNC/4 ( your sequencer, rhythm machine, or converter.
  • Page 42 Recording Insert a tape into the master recorder. Start recording on the master recorder. Press the PLAY key on the MT4X to start playback. The synchronized mixdown will be carried out automatically. Check the recording When the recording is finished, rewind the master recorder and play back the tape.

  • Page 44: Repeat Function

    The REPEAT indicator is illuminated. Repeat notes • If only one memory location is stored, the MT4X will repeat from the tape counter location “0000” to the stored point. • Playback is repeated 16 times continuously, then the tape is rewound back to the first memory location and stopped.
  • Page 45 If you reset the tape counter after the recording, the location displayed will be incorrect. Unlike the memo function, the MT4X does not re-calculate the maximum level memory locations. Clear the maximum level data Press and hold the STOP key (...
