MOTU Issue: “Phase Accurate” versus “Sample Accurate” Sync
Both “Phase Accurate” and “Sample Accurate” sync will give you tight synchronization, but sample accurate sync will give you a higher degree of accuracy.
Phase accurate sync takes place when synchronizing to an external MTC or LTC source, and DAWs (Digtial Audio Workstations) locate and synchronize to the nearest sample location. If the address and the Word Clock are phase-locked, audio drift will not occur. Sample-accurate sync cannot take place since the sync source(LTC or MTC) cannot send a sample location. The tightest resolution from LTC or MTC is quarter-frame accuracy. Using the MTP AV or DTP with a LTC or MTC timebase will phase-lock devices and give you Phase Accurate Sync.
Sample Accurate sync refers to the ability for machines to locate and synchronize to exact sample locations. Adat Sync, Tascam Sync, and Control track have the ability to send address and Word clock in one cable which will be accurate down to the sample location. Digital Performer supports several hardware configurations where sample-to-sample accuracy is possible. 1) ADAT with Korg 1212, 2) ADAT with 2408, 3) ADAT, MTP AV with 2408, 4) ADAT, Digital Timepiece with 2408 and 5) DA-38, DA-88, Digital Timepiece with 2408. Since DP can sync to sample address via the ADAT port or Control Track port (DTP only), you can now achieve full sample-to-sample accuracy when synchronizing.

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.
