World renowned console manufacturer Harrison will be releasing version 3.4 of their software Mixbus and Mixbus32C next week. As well as the normal bug fixes and minor improvements comes a new feature for maximising phase relationships in multi-mic recordings. It’s so clever and yet so simple, I can’t believe we haven’t seen something similar to this before. There is also a new plugin for gating toms, based on some intelligent parameters. Mixbus continues to impress.


Mixbus & Mixbus32C v3.4: Polarity Maximizer

Explained in the video below is the new feature found in version 3.4 called ‘Polarity Maximizer’. It’s a shame they can’t spell it correctly, but otherwise this is one of those features which is likely to prove to be powerful yet so simple. It’s very much implemented within the DAW itself, rather than running like a plugin inserted on the channels. Via reading RMS values of summed channels from a multi-mic recording, it mathematically calculates the best combination of polarity settings across those channels. I often spend ages with a drum or orchestral recordings, flipping phases to see which ‘voices’ best before applying any other processing. I’m really impressed with this tool, I just wish they could rotate phase up to 180 degrees rather than simple inverting, as this would achieve an even more accurate result. Maybe this will eventually come in another update.

This demonstrates the various DAW’s currently available are growing further apart, each becoming an increasingly different proposition. Even I, who spends most of my time inside Pro Tools, am recognising the alternatives that are being developed in exciting ways. If developers like Harrison keep going like this to fight the competition, end users are certainly in for a treat when it comes to technical advances.

Mixbus XT-TG Tom-Tom Gate Plugin

This new plugin – which we haven’t seen or heard yet – is apparently aimed at gating toms in a multi-channel drum recording. I suspect, however, that these gates could of course be used in many other scenarios. As well as all the usual parameters, there are 3 new features not found on standard gates:

  1. There’s the ability to ‘train’ the plugin to the sonic character of the toms and the character of the ‘spill’ separately, so that nearby sounds from the rest of the kit don’t trigger the gate.
  2. There will be a ‘strike’ feature so that only hit’s on the toms trigger the gate, and not resonances educed by other drums.
  3. Best of all, the plugin will be able to write its own automation data so that the user can edit when the gate will open to avoid destructive editing.

Again, this looks like a really powerful tool developed for professional engineers. It also addresses a very common problem we all face from time to time. Keep up the good work Harrison!
