7 chapter 2 ASIO Driver ASIO Driver Capabilities The ASIO Driver is a single-client, multichannel sound driver that allows third-party audio programs that support the ASIO Driver standard to record and play back through qualified Pro Tools audio interfaces. Full-duplex playback of 24- and 16-bit audio are supported at sample rates up to 96 khz, depending on your Pro Tools hardware and ASIO-client program used (such as Cubase or Reason). The ASIO Driver provides up to 18 channels of input and output, depending on your Pro Tools hardware: Up to 8 channels of I/O with Pro Tools HD systems Up to 16 channels of input and 18 channels of output with 003, 003 Rack, and 003 Rack+, Digi 002, and Digi 002 Rack. Up to 8 channels of input and 6 channels of output with Eleven Rack Up to 4 channels of input and 2 channels of output with Mbox 2 Up to 2 channels of I/O with Mbox 2 Mini 2 channels of output with Mbox 2 Micro Visit for the latest Windows audio drivers for Pro Tools hardware, as well as current known issues. Limitations of the ASIO Driver The ASIO Driver cannot be used with multiple applications at the same time. Only one application at a time can use the ASIO Driver. Be sure to disable the Windows system sounds. It is also recommended that you use a separate sound card for games or other general work. Chapter 2: ASIO Driver 3

8 ASIO Driver Control Panel Configuring ASIO Driver settings can be done using the ASIO Control Panel, which is accessed within some third-party ASIO-compatible client applications. Accessing the ASIO Driver Control Panel To access the ASIO Driver Control Panel from a third-party application: Refer to your ASIO-client program s documentation. For example, with Propellerhead Reason, click the Control Panel button. The ASIO Driver Control Panel cannot be accessed under the following circumstances: When Pro Tools is running. When playing or recording in an audio program that does not support the ASIO Driver. When using a third-party audio program that has an option to keep the ASIO Driver open even when you are not playing or recording. (You must close the audio program before you can open the ASIO Driver Control Panel.) Using the ASIO Driver Control Panel From the ASIO Driver Control Panel, you can change the Buffer Size setting or access the Hardware Setup dialog for your Pro Tools hardware. Control Panel button ASIO Control Panel Setup Example, using Propellerhead Reason 4 Windows Audio Drivers Guide

9 Buffer Size You may select from the following buffer sizes (depending on your Pro Tools hardware): 128 samples 256 samples 512 samples 1024 samples 2048 samples Small buffers have the advantage of low latency in the record monitor path. (Latency is the time delay between a signal entering the audio inputs and leaving the outputs during recording.) Larger buffers have the advantage of making the ASIO Driver more immune to audio dropouts during playback and recording. Device The Device setting is always set to your installed Pro Tools hardware. Advanced Button The Advanced button opens the Hardware Setup dialog for the Pro Tools hardware that you are using. For more information on the Hardware Setup dialog, refer to the Pro Tools Reference Guide or the User Guide that came with your Pro Tools system. In some ASIO-compatible audio programs, performing various tasks will interrupt the ASIO Driver and may result in clicks and pops in audio playback or recording. Choosing medium or large buffers (such as 256, 512, or 1024) can help alleviate this problem. Changing the Buffer Size setting for the ASIO Driver does not affect the H/W Buffer Size settings in the Pro Tools Playback Engine dialog. Chapter 2: ASIO Driver 5
