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 settings: 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 and economy tracks (see below), 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.

Device Resolution/Driver Communication: 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. Sequoia 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, performing a dithering. Often 32 bit data transmission is dithered to 24 bit or 16 bit. The 32-bit setting is particularly recommended if no dithering is desired or if the input is not via the sound card's A/D converters but directly digital from a DSP card.

With the MME driver system, however, Sequoia 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.
