Best Controller for oeksound Soothe2 (2026)

If you're looking for the best controller for oeksound Soothe2, you probably already understand what makes this plugin different from every other EQ or dynamic processor. Soothe2 doesn't just cut frequencies, it listens to the incoming audio, identifies problematic resonances in real time, and attenuates them dynamically without affecting the surrounding frequencies. It's less like an EQ and more like an intelligent, self-adjusting spectral processor that knows which frequencies are causing problems and leaves everything else alone.

What makes Soothe2 both powerful and tricky to use is that its controls are abstract rather than specific. You're not setting a frequency and a cut amount, you're setting global parameters like Depth (how aggressively the algorithm processes), Sharpness (how narrowly it targets resonances), and Selectivity (how picky it is about what counts as a resonance). These parameters interact in complex ways, and their effect changes dramatically depending on the source material. A Depth setting that beautifully tames a harsh vocal might do nothing useful on a bright guitar, or vice versa.

Below, I'll explain why hardware control makes Soothe2 significantly more effective, which parameters benefit most from physical encoders, and what to look for in a controller that can handle real-time spectral processing adjustment.

If you already own a MIDI controller, here's what mapping it to Soothe2 looks like.

You open the plugin, right-click the Depth control, select MIDI learn, and turn an encoder. Repeat for Sharpness, Selectivity, and Wet/Dry. That gives you four core mappings, which covers the global parameters. For per-band adjustments, Soothe2 allows you to draw custom sensitivity curves across the spectrum, you'd need additional mappings for band gain and frequency controls.

The real issue is precision. Soothe2 occupies a unique space in audio processing: it's doing something that's almost impossible to do manually (identifying and reducing resonances across the entire spectrum simultaneously), and the controls that govern how it does this are extremely sensitive to small changes. Moving Depth from 4.0 to 5.0 might be the difference between transparent resonance taming and audible processing artifacts. With a mouse, finding that boundary requires careful click-and-drag with tiny movements. With a generic controller, an unlabeled encoder gives you the physical resolution but no visual feedback about where you are.

Then there's the critical role of Delta mode. Soothe2's Delta button lets you hear only what the plugin is removing, it's the single most important tool for calibrating the processing. If Delta mode reveals that Soothe2 is removing tonal content (not just resonances), you know Depth or Sharpness needs adjustment. Toggling Delta rapidly while adjusting Depth is the core Soothe2 workflow, and it needs to be fast and tactile. With a mouse, you're clicking Delta, listening, clicking it off, adjusting a parameter, clicking Delta again. With hardware, you toggle Delta with one hand while adjusting Depth with the other.

The Auriteq Flow's dynamic displays and instant parameter access make this rapid A/B-while-adjusting workflow natural. But first, let's look at which Soothe2 parameters matter most.

The concept: put Soothe2's global processing parameters on physical knobs so you can find the exact depth and character of resonance reduction by ear, toggling Delta mode and adjusting the wet/dry mix for transparent results.

With spectral dynamic processing, the critical skill is calibration, finding the point where the plugin is removing exactly enough resonant energy without touching the good stuff. Hardware control makes this calibration loop faster and more intuitive because you can adjust and compare simultaneously.

Here are the parameters I'd put on hardware first, and why they matter for spectral processing:

Depth, The most important Soothe2 parameter. It controls how aggressively the algorithm attenuates detected resonances. Too low and the plugin barely does anything; too high and it starts eating into the tonal character of the source. The sweet spot is extremely source-dependent and changes with every track. Having Depth on a physical knob lets you sweep from subtle to aggressive while listening, finding the exact point where resonances disappear without the source losing body.

Sharpness, Controls how narrowly Soothe2 targets each resonance. Higher sharpness means the plugin affects very narrow frequency bands around each resonance, leaving more of the surrounding spectrum untouched. Lower sharpness means broader processing that catches more resonances but affects more of the overall tone. The interaction between Depth and Sharpness defines the character of the processing, and having both on adjacent knobs lets you balance aggression against precision in real time.

Selectivity, Determines how picky Soothe2 is about what it considers a resonance. High selectivity means only the most prominent resonances trigger processing; low selectivity means the plugin treats more of the spectrum as problematic. This is the parameter that separates surgical resonance taming from broad spectral smoothing, and finding the right setting requires careful listening while adjusting.

Wet/Dry, The wet/dry mix is essential for Soothe2 because the plugin's processing is so powerful that using it at 100% wet often removes too much character. Blending the processed signal with the dry original at 60-80% wet often produces the most natural results. A physical knob lets you find the exact blend where the resonances are controlled but the source still sounds alive.

Delta, Soothe2's delta mode lets you hear only what the plugin is removing from the signal. This is the most critical quality-control tool: if you hear tonal content in the delta signal (not just resonant whistles and harshness), the processing is too aggressive. Having instant toggle access to Delta while adjusting Depth is the fundamental Soothe2 calibration workflow.

Oversample, Controls the oversampling quality of the processing algorithm. Higher oversampling produces cleaner results at the expense of CPU and latency. Having this accessible lets you quickly compare processing quality during critical mix decisions, switching between quality settings without menu diving.

Band Sensitivity, Soothe2 allows you to draw a custom sensitivity curve that tells the algorithm which frequency ranges to focus on. Having band sensitivity on an encoder lets you boost or cut the algorithm's attention in specific ranges, for example, increasing sensitivity in the 2-5 kHz range for vocal harshness or reducing it below 200 Hz to leave the bass alone.

Output Level, Gain compensation after processing. Soothe2 can reduce overall level as it removes resonant energy, making the processed version sound quieter (and therefore potentially "worse" in an unfair A/B comparison). A dedicated output knob ensures level-matched comparison between processed and bypassed states.

Here's a typical Soothe2 session with a mouse: you insert it on a harsh vocal, push the Depth up until you hear the resonances reduce, realize you've gone too far because the vocal sounds hollow, drag Depth back, click Delta to hear what's being removed, hear tonal content, click Delta off, reduce Depth more, click Delta again to verify, adjust Sharpness to narrow the processing, click Delta again. Each step is a separate mouse interaction, and the constant clicking between Delta and parameter adjustments fragments your listening focus.

With a controller: you push Depth up with one hand while your other hand hovers over the Delta toggle. As soon as the resonances start taming, you flip Delta to check what's being removed. You hear some tonal content in the delta, too aggressive. You pull Depth back slightly while Delta is still engaged, and the moment the delta signal becomes purely resonant artifacts, you flip Delta off and listen to the full result. The entire calibration happens in one fluid motion with continuous listening.

The Sharpness and Selectivity refinement is where hardware control really shines. After setting the basic Depth, you sweep Sharpness to find the width of processing that sounds most transparent. Then you adjust Selectivity to fine-tune how many resonances the plugin catches. These three parameters, Depth, Sharpness, Selectivity, form a triangle that defines the character of Soothe2's processing, and adjusting them interactively by ear produces significantly more transparent results than setting them one at a time.

In a mix where Soothe2 appears on vocals, acoustic guitars, cymbals, and perhaps the mix bus, the time savings are meaningful. But the real benefit is transparency, when you can rapidly calibrate the processing with Delta mode and physical controls, you consistently find the setting that removes harshness without removing life. That's the difference between Soothe2 being a subtle miracle worker and Soothe2 being an obvious processing artifact.

Spectral dynamic processing requires fine calibration, instant A/B comparison, and simultaneous parameter adjustment. Here's how the Auriteq Flow addresses each need with Soothe2.

Pre-mapped out of the box. You load Soothe2 on any channel in Ableton, Logic, or FL Studio, and the core processing parameters are already assigned, Depth, Sharpness, Selectivity, Wet/Dry, and Output Level. No MIDI learn, no configuration. Switch to a different plugin and the mappings update automatically.

Dynamic displays for precise calibration. Each encoder shows the parameter name and exact current value. So encoder 1 reads Depth at 3.8, encoder 2 reads Sharpness at 6.2. For Soothe2, where the difference between transparent processing and audible artifacts is often a single digit of Depth, knowing the exact value without checking the screen is essential for repeatable results.

Delta mode integration. The Flow's layout provides instant access to Soothe2's Delta toggle alongside the Depth control. This means the core calibration workflow, adjust Depth while toggling Delta to verify, happens entirely on the hardware, with both controls under your fingers simultaneously.

Adjacent parameter pairing for the calibration triangle. Depth, Sharpness, and Selectivity are the three parameters that define Soothe2's processing character, and they need to be balanced against each other. The Flow puts them on adjacent encoders so you can adjust all three in a single fluid motion while listening to the result.

Consistent across your processing chain. If you're using Soothe2 alongside dynamic EQs like Pro-Q or compressors like Pro-C, the Flow's per-plugin mappings mean each gets its own optimized layout. Jump between plugins in your channel strip and the encoders update to match.

oeksound Soothe2 is one of those rare plugins that does something genuinely unique, intelligent, transparent resonance reduction that would take dozens of narrow dynamic EQ bands to approximate manually. But its abstract, interactive controls mean that the difference between magical and over-processed is a matter of careful calibration, and that calibration is fundamentally an ears-first process that suffers from mouse-based interaction.

A hardware controller transforms Soothe2 calibration from a slow, click-heavy process into a rapid, intuitive workflow. The key requirements are fine-resolution Depth control, instant Delta mode toggling for quality checking, simultaneous adjustment of the Depth/Sharpness/Selectivity triangle, and precise wet/dry blending. Auriteq Flow delivers all of this with pre-mapped Soothe2 support, dynamic displays showing exact values, and a layout that puts the calibration-critical parameters at your fingertips.

For anyone who relies on Soothe2 as a mixing staple, and it has become indispensable for many engineers working with vocals, acoustic instruments, and full mixes, hardware control is the difference between using Soothe2 tentatively and using it confidently.
