RysUpMod vs Soundtoys PhaseMistress
The fast answer: buy RysUpMod for one focused chorus and phaser workflow. Buy PhaseMistress when deep phaser design is the whole reason you opened the session.
If you are comparing chorus and phaser modulation, the real question is workflow: chorus width, phaser sweep, stereo motion, and quick vocal send movement.
Disclosure: This comparison is published by Rys Up Audio, the company that makes RysUpMod. The Soundtoys facts below were checked against official Soundtoys sources on July 24, 2026.
The choice in thirty seconds
Choose RysUpMod
You want chorus width and phaser movement in one modern interface. You care more about getting motion into a vocal, guitar, synth, or send quickly than building a phaser circuit from the ground up.
Best fit: fast chorus, phaser, and stereo movement inside a normal production workflow.
Choose PhaseMistress
You want a dedicated analog phase shifter with 69 styles, two to twenty four stages, six operation modes, custom LFO curves, rhythmic patterns, and envelope response.
Best fit: detailed phaser design, hardware inspired sweeps, and rhythmic modulation that reacts to the source.
What each plugin is actually built to do
RysUpMod is a combined modulation tool. Its shipping build includes a chorus engine with rate, intensity, mix, and wide mode, plus a phaser engine with two LFO rates, stage control, sweep limits, phase, feedback, filters, warmth, and output mix.
PhaseMistress is a specialist. Soundtoys gives it 69 phasing styles, stage counts from two to twenty four, and modes that include LFO, rhythm, step, random, and envelope driven movement.
The price gap is real
RysUpMod is $49.99 outright. PhaseMistress is $99 on the official Soundtoys product page as checked July 24, 2026.
That does not make PhaseMistress overpriced. It gives you a deeper dedicated phaser. The real question is whether those extra phaser modes are worth another $49.01 for your sessions.
RysUpSuite also unlocks RysUpMod and the rest of the current paid plugin catalog at $9.99 monthly on the annual plan. You can still own RysUpMod by itself if that is the cleaner choice.
Where RysUpMod wins
- Two core jobs in one plugin. Chorus and phaser live in the same interface.
- Fast control. The chorus page keeps rate, intensity, mix, and wide mode visible.
- Useful phaser depth without a maze. Two LFO rates, stage count, sweep range, phase, feedback, warmth, filters, and output mix cover the practical movement producers reach for most.
- Simple licensing path. RysUpMod installs and activates through RysUpHub without iLok.
- Lower current entry price. It costs $49.99 outright, or it is included in Suite.
This is the Rys Up position in one sentence: less setup, one clean modulation window, and a price that leaves room for the rest of the chain.
Where PhaseMistress wins
- More phaser structures. Sixty nine built in styles alter the internal phasing design.
- More stage range. It moves from subtle two stage phasing to twenty four stages.
- More modulation modes. Rhythm, step, random, envelope, and custom drawn curves go beyond a normal LFO sweep.
- Source responsive movement. Envelope mode reacts to the dynamics of the incoming audio.
- Broader format support. Soundtoys lists AU, VST 2, VST 3, AAX Native, and AAX AudioSuite.
If the session needs one strange rhythm triggered phaser that becomes part of the arrangement, PhaseMistress is the stronger specialist.

How to test both without fooling yourself
- Load both plugins on separate sends from the same dry vocal, guitar, or synth.
- Match the return levels before judging tone. Louder almost always feels better.
- Start with a slow sweep and low feedback. Listen for movement without losing the center.
- Push the rate and feedback until each plugin becomes obvious. Then back both down.
- Automate one transition into a hook. Speed matters more than feature count when the clock is running.
- Check the result in mono. Keep the setting that preserves the source instead of only sounding wide in headphones.
- Choose the workflow you can repeat. A deep specialist is valuable only when you use the depth.
Stop paying for controls you will never touch
RysUpMod is the commercial pick for producers who want chorus and phaser movement in one fast plugin for $49.99. PhaseMistress earns the extra spend when deep phaser construction is the job.
