Device Settings (Detailed explanations)

 

Select Windows audio and MIDI settings from VSC (DirectSound Off)

Select this setting when using VSC from within an application which use Audio and MIDI simultaneously.
In such cases, the MIDI or audio signals from the application are as shown below.

With you make this setting, Audio and MIDI of Windows' "Controll Panel"-"Multimedia" are set to VSC, allowing audio and MIDI signals from applications using audio devices to be input to VSC.
Audio sounds from the application being input to the VSC Audio device are mixed with sounds of MIDI performances using VSC, and as a result, these sounds can be played back simultaneously. The mixed sound is output to the audio device in the computer's sound system (that is set to the VSC output device).
* Some applications rather output sound directly to the computer's sound system. In such cases, you cannot run VSC MIDI performances and audio playback simultaneously. Either the sounds from the application or the sounds of the VSC's MIDI performance only are played back.
* While audio device is in use with "DirectSound Off" setting, a DirectSound function cannot be used, even if it is present in the function.

Depending on the application, when VSC is playing a MIDI performance, there might be a lag of about 0.4 seconds before actual output of the sound is made from the application. With some applications (games, for instance), the resulting unevenness between the picture and sound may be noticeable; however, this is due to the characteristics of VSC Audio devices.
* No delay occurs when VSC is not playing MIDI performances.

With MIDI applications featuring audio functions, you need to synchronize audio playback and the MIDI performance (correct the time delay), so use this setting.

Furthermore, this setting allows even greater stability (regarding CPU load, other applications, etc.) than that available when VSC's audio output destination is set to DirectSound. We recommend this setting when making performances only with MIDI.

 

Select Windows audio and MIDI settings from VSC (DirectSound On)

When you play back the MIDI performance on DirectSound-compatible applications, we recommend that you set VSC's audio output destination to DirectSound.
In such cases, the MIDI or audio signals from the application are as shown below.

With you make this setting, MIDI of Windows' "Controll Panel"-"Multimedia" is set to VSC, allowing MIDI signals from applications to be input to VSC.
With DirectSound devices selected as the VSC output destination on your computer, MIDI performances using VSC and the sounds from an application can be mixed and output. In such cases, there is no delay in the sound output by the application to DirectSound.

If the VSC output destination is not compatible with DirectSound, the output is made with the aid of DirectSound emulation.

DirectSound emulation uses much more of the computer's processing capabilities than output made using a DirectSound-compatible sound system. Because of this, applications run more sluggishly, and MIDI performances using VSC are more easily disrupted.

With DirectSound as the VSC output destination, sounds of MIDI performances are more susceptible to disruption from your PC's conditions (load conditions, other open applications, etc.) than is the case when use with "DirectSound Off" setting. We recommend that you set VSC's audio output destination to audio device (DirectSound Off) when making performances only with MIDI.
* You must first install DirectX 3 or higher on your computer. If DirectX 3 or higher is not installed, MIDI playback using VSC will not be possible, even when this setting is selected.
* When DirectSound is selected as the VSC output destination, then the VSC audio devices cannot be used.
* While DirectSound device is in use as the sound function, the device cannot be used with "DirectSound Off" setting.
