ASIO (Audio Streaming Input Output): this protocol was
developed by Steinberg. It is highly recommended for its low latency,
multi-channel audio card support, and high performance.
DirectSound: Developed by Microsoft, this is a is a component of
DirectX 5.0 or higher for Windows. How well DirectX works well
depends on your sound card. If you adjust the interface for an
acceptable amount of latency, you may hear glitches and clicks in
the audio output that can only be fixed if you increase latency.
MME (Multi Media Extension): This is the standard Windows
audio driver. Most sound cards support this interface and work with
it quite well. However, MME is even less suitable than DirectSound
for real-time applications due to its comparatively high latency.
Core Audio: This driver for MacOS X is integrated tightly into the
operating system, and works with external soundcards, as well as
the Mac's integrated audio output (known as built-in). Nowadays,
many audio interfaces support Core Audio out of the box. They are
simply "plug and play." Others, however, may require an additional
driver to be installed. Please check your audio interface's
documentation for further information.
When using Kontakt Player 2 as a standalone application, the
program communicates directly with your soundcard. Therefore, it is
necessary to specify Audio and MIDI settings, as well as the
preferred driver protocol.
Setup for Mac and Windows machines is essentially identical, except
where indicated. Note that if you change your soundcard, you will
need to re-adjust these settings.
Call up the Audio and MIDI Settings dialog from the Setup menu.
You'll see two tabs: Soundcard and MIDI.
