ARTURIA – B-3 V – USER MANUAL 9
 Output Channels lets you select which of the available outputs will be
used to route audio out. If you only have two outputs, only two will
appear as options. If you have more than two you can select a specific
pair of outputs.
 The Buffer Size menu lets you select the size of the audio buffer your
computer uses to calculate sound. A smaller buffer means lower latency
between pressing a key and hearing the note. A larger buffer means a
lower CPU load as the computer has more time to think, but can result
in higher latency. Find the optimum buffer size for your system. A fast,
modern computer should easily be able to operate at 256 or 128 sample
buffer size without creating pops or clicks in the sound. If you are getting
clicks, try raising the buffer a little. The latency is displayed on the right
hand side of this menu.
 The Sample Rate menu lets you set the sample rate at which audio is
sent out of the instrument. The options here will depend on the capability
of your audio interface hardware though even most computers’ own
hardware can operate at up to 48kHz which is perfectly fine. Higher
sample rates use more CPU power so unless you have a good reason to
go up to 96kHz, then 44.1 or 48 are usually fine. The Show Control Panel
button here will jump to the system control panel for whatever audio
device is selected.
 Play Test Tone helps you to troubleshoot audio issues by checking that
sound can be heard through the correct device.
 Your connected MIDI devices will appear in the MIDI Devices area when
they are available. Click the check box to accept MIDI from the device
you want to use to trigger the instrument. In standalone mode, B-3 V
listens for all MIDI channels so there’s no need to specify a channel. You
can specify more than one MIDI device at once.
2.2.2 Audio and MIDI settings: Mac OS X
The process is very similar to setting up for Windows and the menu is accessed
in the same way. The difference here is that OS X uses CoreAudio to handle
audio routing and within that, your audio device will be available in the second
dropdown menu. Apart from that, the options work the same way as described
above in the Windows section.
