Digidesign DirectConnect - 5.1.1_128

The standard versions of DirectConnect v5.1 and v5.1.1 that are installed with your Pro Tools v5.1 or v5.1.1 software provide a 512 sample buffer for streaming audio into Pro Tools. This newer version of DirectConnect 5.1.1_128 has a much reduced buffer size of 128 samples. The smaller buffer results in much lower audio latencies that now range well below 9 milliseconds for TDM systems and below 12 milliseconds for Pro Tools LE (at 44.1 kHz sampling rate). This means that if you play notes on your DirectConnect compatible synthesizer (such as Native Instrument's Reaktor) you will most likely no longer perceive latency. Important to note: A side effect of the lower buffer size is a higher load on your host CPU. In extreme cases, you might not be able to reach the same level of performance achieved with the standard version of DirectConnect. If you experience excessive “low CPU” warnings, or even audio dropouts, we recommend going back to the shipping version of DirectConnect.
