ASIO Settings

Driver System: Select the driver to use from the list of ASIO devices installed on the system. Use the Control Panel button to open the driver's settings dialog. Next to ASIO Buffer in the display field you can see the buffer size and bit resolution set in the driver. The output and input latencies are also displayed.

The entries in the menu Clock Source are provided by the sound card driver. There some sound cards offer the possibility to synchronize the sound card to an external clock.

Buffer/Performance: At VIP object buffer the buffer size for the Economy Engine is set. In the preset Monitoring/Engine mode Mixer FX Monitoring/Hybrid Engine it is used only for playback of objects, its size does not matter for recording and monitoring latency. Only when changing the playback position or starting the playback, smaller buffer sizes result in a faster reaction of the program. In the other monitoring modes, processing of track effects also takes place in this engine, so the buffer size plays a role in the playback delay (latency) there.

The VIP object buffer size should be larger than the ASIO buffer size and between 1024 samples and 8096 samples.

Multi CPU Support: Music Studio supports the use of multi-core CPUs so that different tasks are distributed to different cores. If you have chosen MME or WDM as driver system, audio processing runs mainly on the first core. Disk I/O operations, graphics and video playback are calculated on the other cores. At ASIO the tracks of the mixer with their effects are distributed to the first cores. Object effects, graphics and video playback are distributed to other available cores. By default, Music Studio always uses all cores of the CPU. In case of compatibility problems with certain plug-ins, you can reduce the number of cores used.

Device Adressing: Here you can select the bit resolution for addressing audio devices. The preset value correlates with that of the sound card installed on your system.

The ASIO driver system specifies the bit resolution of the ASIO drivers. Music Studio always adopts the bit resolution set in the ASIO driver. The setting determines whether the data received from the sound card is converted to a different bit resolution.

With the MME driver system, however, Music Studio opens the driver with the bit depth set under Devices/Driver Communication. If the device cannot process the set bit resolution, a correspondingly lower resolution (with dithering) is generated and the MME driver is used with this resolution.
