Free-wheel for time code loss

When this option is selected, playback will continue for a specified period of time without chasing if timecode is lost for some reason. Enabling this option can compensate for infrequent losses in timecode. If losses in timecode are frequent, troubleshooting should be done to find the cause of the problem.

Free-wheel slack time

Use the up and down arrows or enter a value in the edit box to specify the amount of time that timecode can be lost before the Free-wheel playback time starts. A longer time is more tolerant of breaks in the incoming timecode.

Free-wheel playback time

Specifies the amount of time that playback will continue after the Free-wheel slack time has been exceeded.

Synchronization delay time

Use the up and down arrows or enter a value in the edit box to specify the amount of time it takes for to synchronize itself to incoming timecode.

On slower computers, this time should be set to approximately two seconds. On faster computers, it may be set lower.

Setting this value too low can sometimes result in audible pitch shifting at the start of playback.

Offset adjust

If synchronization is consistently behind or ahead of your MTC generator, enter a value in the box to adjust a synchronization offset with quarter-frame accuracy.

• If synchronization is behind, set this value to a negative number. A setting of - 4 usually does the trick.

• If synchronization is ahead, set this value to a positive number. A setting of +4 usually does the trick, though it is rare that Vegas software will sync ahead.

Full-frame message generation

This option specifies when to send full-frame timecode messages while Generate MIDI Timecode is enabled. Full-frame messages are used by some external synchronizable audio devices to seek to a proper location prior to actually starting synchronization. Tape-based recorders especially benefit from seeking to full-frame messages because of the time it takes to move the transport to the proper location. However, full-frame messages are ignored by some devices and may actually cause unexpected behavior in other devices.

Check your hardware documentation to find out if they support full-frame messages.

Send Start instead of Continue when beginning playback

Select this check box if you want to send a Start command rather than a Continue command when Generate MIDI Clock is enabled.

When the check box is cleared, a Continue command is sent, as this type of command allows the chasing device to start from a specific time. However, some older sequencers that support MIDI clock chase do not support the Continue command and must start playback from the beginning every time.

Song Position Pointer generation

This option specifies when to send Song Position Pointer messages while Generate MIDI Clock is enabled. Song Position Pointer messages are used by MIDI applications and devices to seek to a proper location prior to actually starting synchronization.
