Audio Unit Plugins not showing up in DP4
If you have installed an AU plugin and it is not showing up in DP 4.1 or higher, first check that it is properly located in:
Macintosh HD/Library/Audio/Plug-Ins/Components
If it is not, reinstall the AU plugin. If it is in the Components Folder and DP is still not seeing it, check that the “MAS AudioUnit Support.bundle” is located in:
Macintosh HD/Library/Audio/Plug-Ins/MAS
If it is not, download and install the “DP 4.12 MAS and AU Support Bundle Update”, found on our DP downloads page for OS X.
If you are still experiencing problems, you can force DP to examine AU plugins by trashing the “Audio Unit Info Cache” located in your user’s Library/Preferences/Digital Performer.
Next time you launch DP it will examine your AU plugins to determine which ones will be stable in DP. If DP passes the AU you are trying to load you should find it as an insert in the mixing board or if it is a soft synth under the Project Menu > Add Track > Add Instrument Track. If your plugin is not passed by DP, report this to MOTU and the maker of the plugin.
A report on which AUs are passed on your system can be found in your User’s Documents folder called, “MOTU AU Test Results.txt”

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.
