Troubleshooting

 

No sound is produced

* If the computer features multiple sound functions, it may be necessary to select the correct function. Click on the VSC Helper icon in the taskbar, select "Select Output of VSC ," and select the desired sound function.
* If you use VSC as a sound module with other software, refer to "Use As a Sound Module with Other Software."
* Open the Settings window, and confirm the "Volume" setting in the Performance settings.
* Click on the speaker icon in the taskbar, and check to make sure that the volume is not turned down.

 

The Volume is Too High or Low

There are several methods of adjusting the volume of VSC .
Make adjustments according to your platform as well as to suit your particular purposes.
* Setting for the VSC
Click the "SETUP" button in the VSC Main window and change the value for "Volume" in the Performance settings to adjust the volume.
* Volume Control in Windows
Click the Volume Control icon on the taskbar, display the volume slider, and drag the slider to adjust the volume.
* Setting on the computer
You can also use your computer to adjust the volume if it features a volume control.

 

VSC sounds with some delay

When VSC is used as a sound generator with other sequencing programs, etc., VSC sounds with some delay from the display of the program. This is due to the specifications for the software synthesizer. Lower the value for "Sound Response" in the Performance settings of the Settings window to lower the sound delay.

 

Sometimes the sound is cut off, or the same phrase is looped

* There may be interruptions in the sound if a power management function is employed. If this happens, please turn off the power management function.
* Other software starting up or quitting during performances can cause interruptions in the sound.
* Access made to the floppy disk drive or the CD-ROM drive may interrupt the sound.
* Some software places an additional load on the computer, and may prevent some of the necessary number of voices from being played. Quit any software not in use.
* You can improve the situation somewhat by changing the settings in the Performance settings of the Settings window.
- Raise the values for "Polyphony Limit" and "CPU Load Limit."
- Turn off any of the Reverb," "Chorus," "Delay," or "TVF" functions, or turn them all off.
- Lower the value for "Sampling."
- Raise the value for "Sound Response."
* The sound is interrupted or the same phrase is looped when the VSC output is set to DirectSound. Set to "DirectSound On" in the Device Settings of the Settings Window, and try switching the settings.

Furthermore, this is not the limitation when the MIDI data being performed greatly exceeds the capacity of your computer to express sound.

There also are some other cases where the sound is cut off, depending on your PC?s configuration (due to other drivers or software).

 

The number of voices expressed seems low

* Some software places an additional load on the computer, and may prevent some of the necessary number of voices from being played. Quit any software not in use.
* You can improve the situation somewhat by changing the settings in the Performance settings of the Settings window.
- Raise the values for "Polyphony Limit" and "CPU Load Limit."
- Turn off any of the "Reverb," "Chorus," "Delay," or "TVF" functions, or turn them all off.
- Lower the value for "Sampling."

There also are some other cases where the number of voices expressed seems low, depending on your PC's configuration (due to other drivers or software).

 

Performance tempos waver.

* Some software places an additional load on the computer, and the tempo may waver. Quit any software not in use.
* You can improve the situation somewhat by changing the settings in the Performance settings of the Settings window.
- Raise the values for "Polyphony Limit" and "CPU Load Limit."
- Turn off any of the "Reverb," "Chorus," "Delay", or "TVF" functions, or turn them all off.
- Lower the value for "Sampling."
* The tempo may easily be disturbed when the VSC output is set to DirectSound. Set to "DirectSound Off" in the Device Settings of the Settings Window, and try switching the settings.

There also are some other cases where the tempo could waver, depending on your PC's configuration (due to other drivers or software).

 

Sometimes the sound is distorted.

Click on the "SETUP" button in the Main window, open the Settings window, and lower the value of "Volume" in the Performance settings.

 

The sounds of VSC are not identical with those of hardware sound modules.

* VSC contains all the sounds needed for providing compatibility with the SC-55 (mkII), SC-88 and SC-88Pro. This allows VSC to play music files created exclusively for those hardware sound modules, using very similar sounds and expression. However, their quality and expression are not completely the same.
By changing the maximum polyphony, sampling rate, or effects; or by switching TVF ON/OFF, the VSC 's sound quality or expression can be heard differently. Please choose "VSC Synthesizer Parameter" - "Default" in the Performance settings of the Settings window. Then, you will get sounds that are closest to those of the hardware sound modules.
* In certain situations, VSC may play back the music files differently, or may not be able to play back the data correctly due to the difference in the following specifications.
- VSC is a 16-part sound generator, and therefore not fully capable of playing back music files for the SC-88/88Pro, which has more than 16 parts.
- VSC does not have the SC-88/88Pro's Insertion Effects, Equalizer, User Instrument, and Bulk Dump functions. There could be situations where VSC cannot play back music files as hoped for, due to the lack of these functions.
- The characteristics of VSC 's TVF are different from those of hardware sound modules. The expression may be heard differently if the data uses TVF control frequently.

 

The sounds and MIDI performance drop out when applications such as games use MIDI performance and audio playback at the same time.

Try the following approache.
* With DirectX-compatible applications, it may be necessary to set the VSC output to DirectSound. Set to "DirectSound On" in the Device Settings of the Settings Window.

 

When Playing Back Standard MIDI Files, A Sound Generator Other Than VSC is plays.

Some applications that play MIDI performances do not follow this setting. In this case, it may be that the MIDI output destination is set by the application. Redo the settings in the application.

 

The Computer Slow to a Crawl

VSC uses the computer's CPU resources to perform processing, so a certain slowdown in computer operations is unavoidable. However, you can improve the situation somewhat by changing the settings in the Performance settings in the Settings window.
* Raise the values for [Maximum Polyphony] and [CPU Load Limit].
* Turn off any of the [Reverb], [Chorus], [Delay], or [TVF] functions, or turn them all off.
* Lower the value for [Sampling Rate].

Setting the VSC output to DirectSound may cause the computer to run more sluggishly than when set to standard sound. Set to "DirectSound Off" in the Device Settings of the Settings Window, and try switching the settings.

VSC holds wave data in memory, so the performance of applications that use a lot of memory may become slowed down. In the Sound Set settings of the Settings window, switching the sound set to [SC-55 Map Compatible Seund Set] may improve performance.

You can improve the situation somewhat by adding memory to your PC.

 

When Playing A MIDI Sequencer Equipped With Audio Functions, the MIDI Performance And The Audio Playback Are Out Of Sync

The MIDI performance and audio playback are not synchronized when equipment other than the VSC audio device is used for audio playback. Make sure that VSC audio device is selected for audio playback in the settings of MIDI sequencer equipped with audio functions.

There also are some other cases where MIDI and audio playback are out of sync, depending on your PC's configuration (due to other drivers or applications).

 

The Pictures And Sound Are Out Of Sync For Applications Such As Games

VSC audio device makes some delay time which takes for MIDI input to be expressed as sound after it is received. Because of this, sound effects may lag behind the images on the screen; this can be distracting during playback. This is a characteristic of software synthesizers. But You can improve the situation somewhat by changing the settings [Response] in the Performance settings of the Settings window.

 

Some Games Simply Freeze After Starting Up

Some applications including some games stop functioning when the screen from another application appears in front of them. This condition can occur when the VSC starts up automatically. In this case, you can remedy the problem by deselecting [Automatically show window when song begins] in the Display settings of the Settings window, setting it so that it does not start up automatically.

 

My Computer Has More Than One Audio Device. I Cannot Choose Which Audio Device Is Used

VSC searches for a free audio device in a certain sequence, and uses the audio device as the wave output destination. If you wish to use a specific audio device, specify the audio device in the Device settings of the Settings window.

 

Sometime The Sound Or Screen Is Disturbed.

Compatibility issues between VSC 's Audio device and other applications may prevent proper synchronization of moving images and sound, with rapid dropouts in the sound and jerky images.

 

Sometimes An "unsupported format" Error Appears, And No Sound Is Played.

That VSC 's Audio device supports Windows's does not necessarily mean that all WAVE formats are supported. For this reason, some applications may not run, or errors may occur. You can avoid this problem by not using VSC .

 

VSC Performs with Incorrect Part Settings

Sound modules are reset when the sound set is switched.
Confirm the Receive Events settings in the Settings window is set to "Receive All", or not.
If not, and you do not want to receive the events, but part settings are changed automatically, change the settings as follows:
* Clear the check of the "Receive sound module reset messages" in the Receive Events settings.
* Clear the check of the "Select "Receive All" when reset the sound module" in the Receive Events settings.
* Clear the check of the "Reset the sound module when switching songs" in the Player settings.
* Clear the check of the "Update MIDI messages when starting playback" in the Player settings.
When you click the "MODE" button in the Controller window, the sound module is reset even if the "ALL Off" setting is selected in the Receive Events settings.

 

Song Files Cannot be Converted to Audio Files

If song files cannot be converted to audio files, confirm the follows:

Your hard disk drive has enough free space, or not
If the target drive is a removable disk (such as ZIP drive), the target disk's protect notch is closed, or not.
If you want to overwrite to the existing file, the file is read-only or not.

 

I Cannot Change the Effects Settings of Drums Part using Controller Window

On drums part, If you want to change the effect settings, you must change the not only part effect settings but also each instrument's effect settings. You can controll only part effect settings using VSC . If you want to change each instrument's effect settings, the instrument's effect setting must be set in the song data.
