MIDI/Sync Preferences

Available only in Sound Forge

Options Menu:
Preferences

Use the MIDI/Sync tab in the Preferences dialog to specify preferences for MIDI and synchronization. To display this tab, choose Preferences from the Options menu and click the MIDI/Sync tab.

What do you want to do?

Specify a MIDI output device

Choose a MIDI device from the Output drop-down list to specify the MIDI output device for synchronization when MIDI Output Sync is enabled.

Specify a MIDI input device

Choose a MIDI device from the Input drop-down list to specify the MIDI input device for synchronization and triggering when MIDI Input Sync/Trigger is enabled.

This is the device through which Sound Forge will receive all MIDI triggering and synchronization input, including SMPTE/MTC, MIDI triggers, and Regions/Playlist triggers.

Specify a frame rate for SMPTE Non-Drop calculations

Select the Use 30 frames per second for SMPTE Non-Drop check box if you want Sound Forge to use a frame rate of 30 frames per second for all SMPTE Non-Drop calculations.

When the check box is not selected, Sound Forge will use a frame rate of 29.97 frames per second.

Limit recording length

When the Bound record time on SMPTE record sync check box is selected, Sound Forge will not allow recording beyond the specified end time. This ensures that your record length is exact regardless of any inaccurate time code.

Use or adjust the internal timer for SMPTE generation

Select the Use internal timer for SMPTE generation check box if Sound Forge should use the internal timer for SMPTE generation rather than position values reported by the sound card driver. Since many sound cards do not report their position accurately, it is usually better to use the internal timer for SMPTE generation.

Choose a value from the Internal timer resolution drop-down list to specify the internal timer accuracy used for generating SMPTE. Low values produce more accurate SMPTE generation, but may also decrease system performance.

Specify playback options if MIDI time code stops

Select the Use free-wheel for SMPTE loss check box to stop playback if the incoming MIDI time code signal stops. When this check box is not selected Sound Forge will continue to play until the user stops playback manually.

In the Free-wheel time box, specify the amount of time that Sound Forge will continue to play after the incoming MIDI time code signal stops. If time code starts again during this time, playback will continue.

In the Free-wheel slack box, specify how fast Sound Forge should expect time code updates before going into Free-wheel mode. If you have a fast machine, this value can be set to a lower value if you want Sound Forge to stop playback immediately when time code is interrupted.

Offset SMPTE playback

Select the Enable SMPTE playback offset check box to specify an offset that will be added to the time displayed in Sound Forge’s play counter. For example, if you want Sound Forge to generate MIDI time code starting at 01:00:00:00, instead of inserting 1 hour of silence at the beginning of your sound file, you can specify that amount in this field.

When using Record Sync, you’ll often want to set this value to the Enable MTC/SMPTE Input Synchronization Start time. Sound Forge’s ruler and play counter will not display this offset.
