ARTURIA – Matrix-12 V – USER MANUAL 21
Audio and MIDI settings window
Starting from the top you have the following options:
 Device lets you choose which audio driver you want to use to route sound out
of the instrument. This might be your computer’s own driver like Windows
Audio, or an ASIO driver. The name of your hardware interface may appear
in this field.
 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 a small 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 44.1k
or 48k is usually fine. The Show Control Panel button will jump to the system
control panel for whatever audio device is selected.
