Pro Tools Multi-Mono Mode with Studio One

 

A fundamental difference between Pro Tools and Studio One is effects handling, which can be confusing for Pro Tools users switching to Studio One (and yes, this tip is based on a true story). When you add an effect with Pro Tools’ mixer insert, you’ll see options for Multichannel and Multi-Mono effects—which Studio One doesn’t have.

Or does it? Actually, not only can Studio One emulate the Pro Tools Multi-Mono mode for people who’ve switched, but there are some advantages that are relevant to Studio One users.

 

In Pro Tools, Multichannel effects are like what we’re used to in Studio One (and other programs), where the effect processes a mono or stereo track. However, Multi-Mono effects insert separate effects for a stereo track’s left and right channels. Normally this is transparent to the user because the effects are linked, and have a single interface, so they seem like a Multichannel effect. However, Multi-Mono’s particular talent is that you can unlink the effects from each other, switch between the two channels in the interface, and process the two channels (or more, for surround) separately.

 

My Pro Tools friend was disappointed, because he would often use this feature when mastering, restoring tracks, working with two-track audio sources, and the like. For example, when prepping a file for mastering, he sometimes limited one channel to tame peaks, left the other channel with minimal limiting, then added a master limiter at the output to provide overall limiting (this isn’t the same as using a conventional stereo limiter, and unlinking the two channels). On occasion, the different channels needed different EQ as well. 

He knew about my Stereo to Virtual Mono blog post, but wanted to have everything in a single track, like Pro Tools. Fortunately, there’s a simple solution (Fig. 1). As an example, let’s use his scenario of wanting different limiters in each channel.

Figure 1: How to implement Pro Tools’ Multi-Mono effects functionality in Studio One.

 

  1. Open the Channel Editor, then click on the Routing button.
  2. Drag a Splitter into the Routing window.
  3. Set the Split Mode to Channel Split.
  4. Insert a Limiter2 into each split.
  5. (Optional) Insert a Limiter2 at the output, to provide the final limiting function.

 

Done! Now the left and right channels have their own limiters. But the Pro Tools guy also realized there was an advantage to Studio One’s pseudo-Multi-Mono mode: he didn’t have to switch between Limiter interfaces. Instead, he could pin them, and see both at the same time. When I reminded him he could bring out the Gain, Threshold, Ceiling, and Release controls for each Limiter to Macro knobs, save that as an FX chain, and use less screen real estate…let’s just say he was a happy camper.

 

This isn’t to diss Pro Tools, which (like any DAW) does some things well, and some things not so well. But it does show that when switching from one program to another, concerns you may have about needing to give up a favorite feature could be irrelevant.
