Metric Halo Adds New Plug-Ins to MIO Console Version 5.1

Metric Halo’s new MIO Console Version 5.1 software/firmware/driver update adds RIAA decoding to all 2d Expanded and +DSP units, Metric Halo’s new TransientController plug-in, and two new primitive plug-in processing blocks. The new release is shipping with new products and is available by free download to all current Mobile I/O users.

Metric Halo RIAA decoder

MIO Console V. 5.1 adds RIAA decoding to all of the integrated EQ plug-ins available on Mobile I/O. With the new RIAA decoding filter, users can connect a turntable RIAA output directly to a high-gain, low-noise input of a Mobile I/O and apply precision RIAA decoding to the signal to recover the original material. This is said to yield a marked improvement in decoding accuracy over the approximate analog filters employed in standard phono preamps.

Available in mono, multi-mono and stereo configurations, the new TransientController signal processing plug-in for Mobile I/O +DSP offers zero-latency, independent modification of the transient and sustain characteristics of the signal being processed. TransientController presents three levels of user interface complexity, ranging from a simple UI with three basic controls to a more complex UI with detailed process metering and advanced processing controls.

Metric Halo recommends this new process for contouring and controlling the transient properties of everything from individual tracks to full mixes. The company states that it can be used to make drum tracks pop, enhance or decrease the initial transients of guitar tracks, increase the average level of full mixes without dulling the transients in the material, and more. Zero-latency processing also allows the TransientController to be used in live situations to enhance individual channels or entire submixes without introducing any processing delay.

MIO Console v.5.1 with the +DSP license also now includes two new primitive plug-in processing blocks for use in graph macros: the EnvelopeDetector block and the MIONCOTransform block. These two new building blocks allow the construction of interesting audio controlled synth elements in the zero-latency +DSP environment.

EnvelopeDetector transforms an audio signal into an audio rate control voltage proportional to the amplitude envelope of the input audio signal. The output control voltage can be used as side-chain input signal, the source of an envelope control signal, or to control the frequency of a Numerically Controlled Oscillator. The second new block is tailored for the last application of the EnvelopeDetector. MIONCOTransform converts a linear control voltage signal to the proper control value to input into a MIO Numerically Controlled Oscillator to sweep between specified minimum and maximum frequencies.

The new plug-ins are part of v.5.1 for the +DSP package for Mobile I/O and are included for free in the v.5.1 MIO Console update for +DSP license holders. The new plug-ins can be added to current 2d Expanded systems, along with more than 100 other plug-ins and macros, by adding a +DSP license to the system. A new +DSP license may be purchased from Metric Halo for $699.

The new software release also includes new features and bug fixes, including a workaround for a FireWire kernel panic, comprehensive Control Surface Support for EuCon and Mackie Control protocols, a fix for intermittent playback issues with the Record Panel, and a new German localization for the software.

Older Metric Halo units may be updated in the field. The updated software is available as a free download from Metric Halo’s Website at The company states that it will ship all new units with the updated software.
