SYNC-RECORDING For synchronized operation with MIDI instruments, the optional YMC10 MIDI converter enables synchrooperation of the CMX1 and MIDI instruments such as the RX11, RX15, and RX21 digital rhythm programmers and the QX1 and QX7 digital sequence recorders. In this section, we will explain synchro-recording using synchro-operation techniques. Merits of synchro-recording Synchro-recording enables the use of digital sources such as rhythm programmers and sequencers during the first mixdown stages. Since these sources are recorded directly onto the master, it extracts the full sound quality, dynamic range, and superb S/N performance of these digital instruments. Operating the tape sync In order to work the tape sync, the MIDI synchronizing signal must be converted to an FSK (frequency shift keying) signal first. This is because MIDI transmits information at an extremely high maximum speed of 31.25 K baud per second. Therefore, the use of analog instruments is impossible. By using the MIDI converter, the MIDI synchronizing signal is converted to an FSK signal that analog instruments can handle. An example of synchro-recording using the RX 15 rhythm programmer Set the RX15 to create the desired rhythm effects. Connect the RX15 in the following manner. With the SYNC switch "ON", press the PLAY switch and the FSK signal recorded on track 1 is sent to the YMC10, which converts it to the MIDI synchronizing signal and outputs it to the RX15. In this way, track 1 of the MT1X operates the RX15. FOR THIS OPERATION, DON'T FORGET TO SET THE RX15 SYNC SWITCH TO "MIDI". Now, tracks 2-4 can be used for overdubbing. Connect as shown below for mixdown. Start the tape, mixdown the sound from tracks 2-4 and the RX15's drum sounds input through the AUX Left and Right jacks, and record it with a stereo tape deck. After putting the MT1X into the REC PAUSE mode, turn the SYNC switch "ON". In this condition, both the tape will start and the RX15 will start playing when the PAUSE switch is pressed. Here's how it works. The YMC 10 converts the MIDI synchronizing signal from the RX15 to FSK signal, which is recorded on track 1 of the MT1X. In order to operate the RX15 by the FSK signal recorded on track 1, connect everything like this: 33
