New Mobile I/O Software Released

Mobile I/O Operating System Version 1.5 Released

March 26, 2004

Metric Halo has released version 1.5 of the Mobile I/O operating system, providing new functionality and increased performance across all Mobile I/O hardware models. Users of the Mobile I/O 2882, 2882+DSP, ULN-2, and ULN-2+DSP can now take advantage of increased performance under Mac OS X. MIO v1.5 results from development efforts designed to address inconsistencies with competing DAW applications, operating system anomalies, computer processing shortcomings and FireWire bandwidth issues. Mobile I/O users can also take full advantage of this newly released package in Mac OS 9.

Mobile I/O v1.5 introduces a new Metric Halo technology, Adaptive CoreAudio Timestamping, or ACAT, which allows the MIO driver to report the active stream rate without variance, and lets clients run at higher CPU loads, increasing overall system performance.

Metric Halo has completely revised the latency management code in the MIO Driver. The new driver provides consistent low-latency at all sample rates and buffer sizes. The new code also allows the driver to run with a reduced output latency as compared to earlier versions of the driver. In consultation with testers worldwide, Metric Halo has tuned the driver reported latency values to ensure that overdub recording is "dead-on" with the current versions of all the major DAW/Sequencer applications that support CoreAudio (including Logic, DP4, Cubase SX and Nuendo).

Version 1.5 also addresses a variety of reported issues with the previous version of the driver, including operation at both large and small buffer sizes, optimized performance for Mac OS X 10.3 Panther and channel naming adjustments for improved compatibility with multibox operation within Digital Performer.

Version 1.5 has enabled all 18 outputs from the computer at 44.1 and 48kHz (14 channels at 88.1 and 96kHz to account for the four-channel reduction in ADAT output with S/MUX operation) with the 2882 line, and adds four new +DSP plug-ins to the +DSP plug-in set: MIO Channel Summer, MIO Channel Differencer, MIO Channel Sum/Differencer, and MIO Delay. These plugs are basic programming building blocks to let users make complex and custom processing routings.

Version 1.5 also adds new system level reset commands to reset various aspects of the Mobile I/O hardware without having to disconnect the hardware from your computer.

Mobile I/O users can download the v1.5 package from the Metric Halo Mobile I/O Drivers Page.
