Troubleshooting Sampling and Sequencing Problems |
Depending on the performance of your system (and your sequencer) you may experience SMPTE sync drop-out problems. This is typically due to too many processes occurring than your computer is capable of maintaining. For example, if you have wave playback, synchronization messages, sequencing, and more occurring at the same time, you may experience sync drop-out.
To compensate for this, many sequencers allow you to set a freewheel time, and you can adjust Sound Forge's freewheel time on the MIDI/Sync tab in the Preferences dialog. This is a slack time between SMPTE messages during which the sequencer will continue to play even if SMPTE/MTC messages are being missed. By increasing the freewheel time, you allow Sound Forge and your sequencer to be less tightly dependent on SMPTE messages, but this may also decrease your synchronization accuracy. Start with a small freewheel time and, if you experience sync drop-out problems, increase the freewheel time until the drop-outs go away.
If you have a large number of MIDI devices in your system or a multiport MIDI board, you may have problems installing additional VMR MIDI interface ports. Windows 98 and Me limit the number of MIDI devices that can be supported (typically between 10 and 12 devices). If MIDI devices cause system errors after installing the VMR, reduce the number of ports in use by the VMR, remove the VMR, or reduce the number of MIDI devices in your system.
