About the items in the Driver Settings Panel

"SAMPLE RATE"

Displays the present sample rate.

 

"Audio Buffer Size"

You can adjust the audio input/output buffer size.

Decreasing the buffer size will shorten the latency and improve realtime performance, but might make it more likely that you will experience audio clicks and pops, depending on your computer's processing power and the song data load.
Increasing the buffer size will lengthen the latency, but will make audio streaming more stable, and it will be less likely for audio clicks and pops to occur.

In general, you'll probably want to decrease the buffer size for better realtime performance if you're playing a software synthesizer in real time, or if you're monitoring an audio input that's being passed through your DAW software.
Conversely, you can increase the buffer size to prevent audio clicks and pops if you're recording or playing back song data that contains numerous tracks and presents a heavy processing load.

By changing the buffer size as appropriate for your situation, you can obtain the right balance between realtime performance and audio streaming stability.

 

"Recording Margin"

If the recorded audio data contains sound dropouts or noise even after you've adjusted the audio buffer size in your software and also adjusted the above "Audio Buffer Size," try increasing this "Recording Margin" setting.

*	For some software, it may not be possible to adjust the buffer size.

 

"Recording Timing"

If the timing of the recorded audio data is not correct, adjust this value.

 

Note)
If you click the [Apply] while your audio software is running, the setting changes won't be immediately reflected. Only after all audio software have been quit, and the software is then started once again will the settings become effective.

Try adjusting the audio buffer size of the driver

If the size of the driver's audio buffer is too small, sound may not be produced, or it may be impossible to carry out normal playback and recording.

In such cases, you should refer to "To change or verify settings," and increase the size of the buffer.

 

Occasional disruptions in the sound or noises occur

Try adjusting the audio buffer size for the software you're using.

First, try adjusting the audio buffer size for the software you're using.
If sound dropouts or noise still occur during playback or recording, try adjusting the "Audio Buffer Size" in the Driver Settings panel.

*	For some software, it may not be possible to adjust the buffer size.

 

Could you have performed a macOS software update while the device was still connected?

If you performed the macOS software update with the device left connected, drop-outs may occur in the sound. If this occurs, please re-install the driver.

 

Is the MC-707 connected to a USB hub?

Try connecting the MC-707 directly to the USB connector of your computer itself.

 

Occasional disruptions in the sound or noises are in the recorded audio data

If the recorded audio still contains sound dropouts or noise even after you've adjusted the audio buffer size as described in "Occasional disruptions in the sound or noises occur" (above), try increasing the "Recording Margin" in the Driver Settings panel.

*	For some software, it may not be possible to adjust the buffer size.
