Chapter 22 Specific Applications

This chapter explains some additional ways to use the VS-1824, including synchronizing two VS-1824s, a VS-1824 and VS-1680, as well as synchronizing (“syncing”) a VS-1824 and a VS-880 or a VSR-880. Press [PLAY (DISPLAY)] to begin each operation from the Playlist display.

The following items will be used from the MIDI page of the system section:

Device ID

This sets the Device ID number (1-32) used when exchanging System Exclusive messages (mixer parameters) with an external MIDI device. These messages can be transmitted and received between devices that have the same Device ID number.

MIDI Thru (MIDI Thru Switch)

This switches the function of the MIDI OUT/THRU connector.

OUT:

The connector transmits MIDI messages such as metronome note messages or MTC from the VS-1824.

THRU:

The connector transmits MIDI messages as received at the MIDI IN connector without any changes.

SysEx.Rx (System Exclusive Receive Switch)

System Exclusive messages are received when this is set to “On.” System Exclusive messages can be received when the VS-1824 is in the Play mode.

SysEx.Tx (System Exclusive Transmit Switch)

System Exclusive messages are transmitted when this is set to “On.”

Cntrl Local (Control Local Switch)

When this is set to “Off,” volume levels of mixer channels cannot be changed using the physical faders on the mixer. The physical mixer faders are disabled. Normally, this setting is turned on.

MMC (MIDI Machine Control Mode)

This setting determines how the VS-1824 implements MMC.

Off:

MMC is neither transmitted or received.

MASTER:

MMC is transmitted. The VS-1824 functions as the master device for controlling the machine controls (transport controls) of external MIDI equipment.

SLAVE:

MMC is received. The VS-1824 functions as a slave device to the machine controls (transport controls) of external MIDI equipment.

Control Type (Mixer Control Types)

This selects the type of MIDI messages used when transmitting mixer settings to an external MIDI device, or when MIDI messages from an external MIDI device are used to control the mixer. For now, leave this “Off.”

Off:

MIDI messages related to mixer settings are not transmitted or received.

C.C.:

The mixer is controlled using Control Change messages.

Excl:

The mixer is controlled using System Exclusive messages.

*When “C.C.” or “Excl” is selected, mixer adjustments made on the master VS-1824 will result in the same mixer settings occurring on the slave VS-1824. For more detailed information about System Exclusive messages, refer to “MIDI Implementation” (Appendices p. 82)

The following items will be used from the External Sync page of the system section:

Sync Source

This determines how the VS-1824 is synchronized with other devices.

INT:

The VS-1824 runs according to its own internal clock. Use this setting when you are not synchronizing with other devices or when you want external MIDI devices to be controlled by sync signals from the VS-1824.

EXT:

The VS-1824 is controlled by synchronization signals (MTC) from the external MIDI device. With this setting, the VS-1824 will not go into Play or Record unless it is receiving MTC signals. Use this setting when you want to use the MTC from an external MIDI device to control the VS-1824.

Sync Gen. (Generator)

This setting determines what type of MIDI signal is generated at the MIDI OUT connector on the VS-1824.

Off: No MIDI signals are transmitted.

MTC: MIDI Time Code is transmitted.

MIDIclk: The Tempo Map MIDI Clock is transmitted.

SyncTr: The Sync Track MIDI Clock is transmitted.

Sync Error Level

This sets the interval (0-10) for checking MTC receiving status when synchronizing to MTC from an external MIDI device. If MTC is not being sent continuously, the VS-1824 checks the MTC and if there is an error, temporarily cancels synchronization. Selecting a longer interval under such circumstances will allow synchronization to continue, even if errors are present. Normally, this is set to “5.”

Sync MTC Type (MTC Type)

This selects the type of MTC (30, 29N, 29D, 25, or 24). Set this to conform to the type of MTC on the slave VS-1824.
