Unity DS-1 Using ASIO Support on the Macintosh
You will need to create a folder called ‘Unity DS-1 ASIO Drivers’ in the Extensions folder. Copy the ASIO drivers you want to use into this folder. To configure the DS-1 for ASIO output, open the Unity DS-1 control panel and select ASIO as the output type. You can select either stereo (stereo output duplicated on output pairs 1/2, 3/4, etc.), or individual mono (MIDI channels 1, 2, … output on the individual outputs), or individual stereo (MIDI channels 1,2, … output in stereo on the pairs of outputs) mode. Press the setup button to get to the Setup dialog, where the appropriate ASIO driver is selected. You also can call up the ASIO driver’s control panel with the ‘ASIO Control Panel’ button. Note, that not all ASIO drivers support a control panel in this manner.
MOTU 2408 Users Note!
The MOTU 2408/1224 uses a PCI-324 driver that needs to have its ASIO driver in a folder named ‘ASIO Drivers’. Therefore, for 2408 ASIO users, you will have to put the PCI-324 ASIO driver in a folder named ‘ASIO Drivers’ in the Extensions folder. Make an alias of this ‘ASIO Drivers’ folder in the Extensions folder called ‘Unity DS-1 ASIO Drivers’. Now everyone’s a happy camper.
There is a cool feature in the PCI-324 Console where you can set the output buffer size to 64, 128, 256, 512, etc. When using ASIO output, the Unity DS-1 will use this recommended buffer size optimally. Lower buffer sizes mean lower latency (that is, faster response time). Experiment with different values for your Macintosh.

Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
