Stereo bus processing – Sonic Hill Recording Studios

To get a truly professional “glue,” you should think of the Stereo Bus as a place for subtle, global enhancement rather than fixing problems.

The key to a professional master bus is the order of operations. Here is the standard “Glue Chain” using only Cubase stock plugins, which are surprisingly high-quality for this task.

The “Pro Glue” Chain Order (Stereo Out)

Position	Plugin	Goal	Typical Settings
1. Utility	Brickwall Limiter (Inactive)	Safety. Keep this at the very end but leave it OFF unless you are checking loudness.	Ceiling: -1.0 dB
2. Clean EQ	Frequency 2	Correction. High-pass everything below 25Hz to remove “sub-mud.”	25Hz HPF (48dB/oct)
3. Glue Comp	VCA / Tube Compressor	Cohesion. This makes the instruments “dance” together.	Ratio: 1.5:1, Attack: 30ms, Release: Auto, Gain Reduction: 1–2dB max.
4. Color EQ	Studio EQ	Polish. Add a tiny “air” boost or a slight “warmth” scoop.	+1dB High Shelf @ 10kHz
5. Saturation	Magneto II	Character. Adds harmonic warmth and tames harsh peaks.	Tape Saturation: 10–20%

Deep Dive: The Cubase “Glue” Plugins

The Compressor: Tube Compressor vs. VCA

VCA Compressor: Use this for punchy, modern tracks (Pop, Rock). It is very transparent and “grabs” the mix quickly.
Tube Compressor (The Glue King): In Cubase, the Tube Compressor is excellent for a “vintage” glue. Use the Auto Release setting; it allows the compressor to breathe naturally with the tempo of your song.
The Rule of 2: On the master bus, you almost never want the needle to move more than 2dB. If it’s hitting 4 or 5dB, go back and fix the individual faders.

The EQ: “Air” and “Body”

Instead of surgical cuts, use Frequency 2 to do a “High Shelf” boost.
The “Air” Trick: A 0.5dB or 1dB boost at 12 kHz makes the whole mix feel expensive and open.
The “Mud” Cut: If the mix feels “boxy,” try a tiny 1dB cut at 300 Hz with a very wide Q.

The Saturation: Magneto II

Tape saturation is the “secret sauce” of the analog era.

Putting Magneto II after your compressor helps “shave off” the tiny transients that the compressor missed.
It makes the mix feel “thick” and cohesive. Keep the “Drive” low—you shouldn’t hear distortion; you should just feel that the mix is “fuller.”

Pro Tip: “Mixing Into” the Chain

Earlier, I suggested moving this step to Step 5.5.

Why? If you add a compressor at the very end of your mix, it will change your volume balances. If you turn it on halfway through your mix, you will naturally make better choices about how loud the Kick or Snare should be because you are hearing how the “Glue” reacts to them in real-time.
