Unfortunately, many new computers don't include a sound card with a built-in MIDI synthesizer, so choosing a "no-latency" MIDI output driver for recording may not be an option. As far as we are aware, there is no way to reduce the latency on any particular computer. The latency of the GS Wavetable varies between different computers - it is usually between 50 and 100 ms. The sounds are somewhat similar to the Roland VSC, but they are lower quality sounds, and there are fewer of them. The Microsoft GS Wavetable is a software synthesizer included with Windows. See the VSC help file if you want more information on each setting:Ĭlick on the Performance tab and uncheck delay and TVF.Ĭlick on the Performance tab and turn the load limit up to 90%.Ĭlick on the Sound Set tab and select 'Secure Memory at all times'.Ĭlick on the Receive Events tab and uncheck any that you do not use (ie - delay, expression.) on all channels.Ĭlick on the Device tab, and set 'Direct Sound' to off.įor best results, close as many background programs as possible. If you have trouble reducing the VSC latency below 100 ms, the following adjustments in the VSC settings window may improve performance without sacrificing sound quality. When you exit the MIDI Driver Setup dialog, Band-in-a-Box ® may ask you if you want to set the driver latency to 430 ms. | MIDI Driver Setup dialog and set the Driver Latency setting to the same value as the VSC's Response Time. If there are no playback problems, you can move the Response Time slider another notch to the left. Go back to Band-in-a-Box ® and try playing a song.Try setting it at about 100 ms to start with. Move the Response Time slider to the left.Click on the button to open the VSC Settings Window.You can do this by clicking on the VSC icon in your task bar and selecting 'VSC Panel', or by going to Start | Programs | Virtual Sound Canvas 3.2. This is still not ideal for live playing, but is much better than 430 ms. Depending on how fast your computer is, you may be able to reduce this to about 100 ms or less. On most modern computers, you can reduce the VSC's latency by a fair bit without experiencing any problems. If you select the Roland VSC as your MIDI Output Driver and press OK in the MIDI Driver Setup dialog, Band-in-a-Box ® will automatically offer to set the latency to 430 ms. This is a safe setting, and will avoid audio drop-outs and glitches even on older and slow computers. By default, the Roland VSC has a response time of about 430 to 450 ms (a little less than half a second). The VSC's latency, or "Response Time", is adjustable. The Roland VSC is a software synthesizer based on the sounds from the Roland Sound Canvas hardware sound modules. This information is only applicable to the stand-alone version of the VSC, not the VSC-DXi plugin. Here is some more information about the Roland VSC and Microsoft GS Wavetable. If you prefer the sound quality of the soft synth, you can record using a no-latency driver, and switch back to the soft synth for playback when you have finished recording. This could be the built-in MIDI synth on your computer's internal sound card, or your external MIDI keyboard or sound module. There will still be a delay between when you strike a key on your keyboard and when you hear the note played.įor recording or playing live from an external MIDI synth, the solution is to use a MIDI Output Driver with no noticeable latency. However, note that this is only a visual setting it doesn't change the actual latency of the driver. | MIDI Driver Setup dialog is used to delay the notation and chord highlighting so that it is synchronized with the music during playback. In Band-in-a-Box ®, the Driver Latency setting in the Opt. This delay is called latency, and is normally a fraction of a second. In other words, there is a delay between when a note is sent by Band-in-a-Box ® (and other MIDI software) and when you hear the note played. One characteristic of a software synth is that it takes some time for it to express the MIDI data it receives as sound. You are most likely using a software synthesizer such as the Microsoft GS Wavetable or the Roland VSC as your MIDI output device. Why is there a delay between when I play a note on my MIDI keyboard, and when I hear the note play through my computer speakers?
