Optimizing your OSX system for DP4.
Optimizing your OSX system for DP4.
Mac OSX makes it much easier optimize your system for Digital Performer 4. You no longer have to allocate RAM or trim extensions as we did in earlier Mac operating systems.
A. MOTU currently recommends having the latest versions of OSX; 10.3.9 or 10.4.1. Check www.motu.com for software updates and compatibility information.
B. Be sure to update to the latest version of DP. Check for DP updates at www.motu.com. You’ll also want to make sure your audio and midi hardware has the latest available drivers.
1. In SETUP > CONFIGURE AUDIO SYSTEM > Configure Hardware Driver : Set “Host Buffer Multiplier” to 1 (one) if you’re using one audio interface (if you’re using two, you can leave it at it’s default level 2).
2. In SETUP > CONFIGURE AUDIO SYSTEM > Configure Studio Size : Set “Disk Read Write” to 150, and “Buffer Size per Voice” to 150.
C. We recommend these Mac OSX settings in order to avoid conflicts while Digital Performer is running. From the Apple Menu, choose System Preferences, and make the following adjustments:
1. Click ENERGY SAVER. Set “Put the computer to sleep….” to NEVER.
2. Return to System Preferences by clicking “Show All”, and click SOUND. In the Sound Effects page, turn OFF the item “Play user interface sound effects”.
3. Return to System Preferences by clicking “Show All”, and click QUICKTIME. In the Update page, turn OFF “Check for updates automatically”.
4. Return to System Preferences by clicking “Show All”, and click CLASSIC. In the Start/Stop page, turn ON “Warn before starting Classic”.
7. Return to System Preferences by clicking “Show All”, and click SOFTWARE UPDATE. In the Update Software page, turn OFF “Automatically check for updates…”
You can periodically check for updates, by clicking the “CHECK NOW” button in the Software Update panel. We recommend that you QUIT all applications before doing this.

Offer applies only to single-receipt qualifying purchases. Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. 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. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

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.
