Hey I thought I’d share a custom effect preset:
ms-tweak.unit (39.9 KB)
This would be placed in : /ER-301/v0.4/presets/custom-effect
-OS 0.4.25 required! (it uses the mono source mixer introduced in this version)
-this MUST be loaded on a stereo-linked channel otherwise it won’t work
What it does:
This is a Mid-Side encoder/decoder and processor. For anyone not familiar with M/S processing - it allows you to modify phantom centre (the ‘Mid’) Independent of the ‘stereo’ content (the ‘Sides’). This offers significantly more nuanced control of a stereo mix than using standard stereo effects.
How it Works:
Internally, it’s a 3 step process:
- Encode to MS: Converts the incoming stereo signal to Mid and Side elements
- Process: Allows you to add independent audio processing to the M and S signals
- MS Decode: Reconverts the MS signal back to a regular stereo output.
There is no need to dive into the internals, as everything is on the surface:
M and S faders
These affect corresponding volume levels. You can assign these to external faders such as a 16n or 5v CV source. It’s set so 0-5v is 0 to 1 on the fader. If both are M and S are set to 1, then M and S are at unity and the output of this custom effect will sound identical to the input source. The max can be set to 2 if need be so you can crank up beyond nominal.
This fader isn’t adjustable. Instead, enter this subchain and add any mono effects you want to use to process the “MID” / phantom centre.
This fader isn’t adjustable. Instead, enter this subchain and add any mono effects you want to use to process the “SIDE” / stereo content.
Have a stereo source/sample to the left of this custom-effect. If using no external CV, set both M/S faders to 1 as a start. Lower the M fader. All centre content should lower until completely gone at a 0 setting.
Tip: This is a great way to analyze song mixes as you can hear what verbs and stereo fx are used
Tip: You can EQ and compress the M and S separately: It’s the backbone of stereo mastering
It’s best used for modern/traditional mixing: ie: Bass/Kick/Snares/Lead Vocals are centre panned. It’s not intended for super old-school content before engineers knew what to do with stereo (ie: all the drums/bass left and vocals and guitars right etc).
It’s a specific type of processor, but for those who can make use of it, enjoy!
