Demo summary

The narrator applies the new TTM (To The Max) style to a drum bus and demonstrates the improved sidechain EQ with up to six bands to control frequency-specific compression thresholds.

Step-by-step

Select the TTM style algorithm on the drum bus
Adjust the threshold to determine which part of the transfer curve is being utilized
Use the ratio control to set the amount of compression
Open the sidechain EQ to access frequency-specific threshold control
Add up to six bands in the sidechain EQ to target specific frequencies

Options

Use a high shelf band in the sidechain to control the threshold for just the high frequencies

Watch out for

The threshold control in TTM style works differently than other algorithms because it combines downward and upward processing

Tips

Use TTM style to get powerful multiband processing without the complexity of a conventional multiband compressor
Boost a frequency in the sidechain to effectively reduce the threshold for just that frequency

Highlights

“this is a great way to get very powerful multiband processing without the fuss and complexity of a conventional multiband compressor”
