Edit spectra with the MatchEQ Action menu
This menu provides commands that can be applied to the either the Reference or the
Current Material spectrum.
• In MainStage, choose one of the following from the Action menu:
• Clear Current Material/Reference Spectrum: Clears the current spectrum.
• Copy Current/Reference Spectrum: Copies the current spectrum to the Clipboard
(this can be used by any MatchEQ instance in the current project).
• Paste Current/Reference Spectrum: Pastes the Clipboard contents to the current
MatchEQ instance.
• Load Current Material/Reference Spectrum from setting file: Loads the spectrum
from a stored setting file.
• Generate Current Material/Reference Spectrum from audio file: Generates a
frequency spectrum for an audio file you have chosen.
Refine the Match EQ curve
Each time you match two audio signals, either by loading or learning a new spectrum while
Match is activated or by turning on Match after a new spectrum has been loaded, any
existing changes to the filter curve are discarded and Apply is set to 100%.
In MainStage, do either of the following:
• Drag the Apply slider down from the default 100% value to avoid extreme spectral
changes to your mix.
• Drag the Smoothing slider to adjust the spectral detail of the generated EQcurve—if
required.
Use the matched EQ on a channel strip
MatchEQ creates a filter curve based on the differences between the spectrum of the
template and the current material. This curve automatically compensates for differences in
gain between the template and the current material, with the resulting EQcurve referenced
to 0dB. A yellow filter response curve, showing the average spectrum of your mix, is
visible in the main display when the EQ Curve button is active. This curve approximates
(mirrors) the average spectrum of your source audio file.
1. In MainStage, choose the channel strip that you want to match from the Sidechain pop-
up menu of the MatchEQ window.
2. Click the Reference Learn button.
3. Play the entire source audio file from start to finish. To stop the learn process, click the
Reference Learn button again.
4. Return to the start of your mix, click the Current Learn button, and play your mix (the
current material) from start to finish.
5. When you are done, click the EQ Curve Match button.
