LightBridge Anomaly
To check intercomputer latency using the LightBridge, I performed the following test:
With a snare on track one I patched an ADAT cable from ADAT 1 out back into ADAT 1 in. I played the snare through the loop and recorded it on track two, expecting to see a small amount of latency. The snare on track two was recorded 134 samples BEFORE track one. Changing PT Hardware Buffer size had no effect. Can anyone confirm this? It appears that Pro Tools MP is attempting to adjust for input delay, but it is overcompensating. 134 samples at 44.1 is not even close. Gene Pro Tools M-Powered 7.3 ProFire Lightbridge V1.8.1-3 G5 OSX 10.4.8 44.1, 24bit LigthBridge on internal clock with no additional connections.
