Also, increase the volume faders ofthe instruments themselves — the 424 MKIIIchannel and master faders should not haveto be "full up" at any time.Incorrect tape sync. Try re-recording sync tones by adjustingthe MASTER fader between –10 to 0 dB on thetrack 4 meter.Problem Possible CausePlayback sounds dull Dirty headsPlayback level is low Dirty headsTransport keys not effective Power turned off, or tape not loadedNo tape motion PAUSE pressedRECORD FUNCTION set to SAFE,No recording cassette tab broken, or REHEARSALengagedWrong tracks recorded PAN improperly setIncorrect playback pitch PITCH CONTROL set to a differentposition than during recordingFeedback occurs during ping-pong Level is too high or EQ HIGH isrecording excessively boosted38Troubleshooting37Syncing MIDI-Tape1Using the TASCAM MTS-30MIDI clocks are themselves a computer type digital language andcannot be recorded on analog tape; it is necessary to convert them torecordable FSK (Frequency Shift Keying) signals using an appropriateconverter, such as the MTS-30.The MTS-30 is not a mere MIDI-FSK converter but translates MIDIclocks into an FSK sync signal containing score "bar" information or"Song Position Pointer", allowing the associated MIDI equipment tostay in sync and follow the tape no matter where you move the tapewithin a given song. The maximum stability or resolution of thesynchronization is ensured by a TASCAM-exclusive error correctioncircuit in the MTS-30.1. Connect the TAPE OUT of the MTS-30 to the SUB IN "R" of the424 MKIII, and the TAPE OUT 4 of the 424 MKIII to the TAPE IN ofthe MTS-30.2. Set the TRK 4 RECORD FUNCTION switch to BUSS R.3. Locate the DBX NR switch on the back panel and set it to theSYNC position. This defeats the dbx encode/decode for track 4only.● When recording FSK signal, adjust the MASTER fader of the 424MKIII to get a reading on the track 4 meter of from -10 to 0 dB.We suggest that you input the "virtual" tracks from the MIDI system toSTEREO INPUTS 7 and 8. Set the ASSIGN switch of these inputs toMON while recording, and to L-R position on mixdown.
