Measurement And Adjusted Files

MatchPatch works with three kinds of Helix files during a normal workflow:

  • your original file;

  • a measurement file;

  • an adjusted file.

Knowing the difference helps you avoid importing the wrong file before a gig.

Original File

This is the .hls setlist or .hlx preset you already have.

Keep a backup of it before running MatchPatch.

Measurement File

A measurement file is a temporary Helix file made for measuring. MatchPatch changes routing so the computer can send the reference DI into the Helix and record the processed output.

Measurement files often use _measurement in the filename.

Example:

Songs.hls
Songs_measurement.hls

Warning: A measurement file is for measurement only. Do not use it as your final live setlist or preset.

Adjusted File

An adjusted file contains the level changes MatchPatch calculated.

This is the file you import back into the Helix after checking the results. Adjusted files often use _adjusted in the filename.

Example:

Songs.hls
Songs_adjusted.hls

Save, Save As, And Save Measurement File

In the GUI:

  • Save writes the current MatchPatch changes to the active Helix file.

  • Save As writes the changes to a new Helix file.

  • Save Measurement File creates a measurement file for the workflow.

Use Save As when you want to keep the original file untouched.

File Extensions

The output file should keep the same extension as the input:

  • .hls setlists save as .hls;

  • .hlx presets save as .hlx.

MatchPatch will warn you if the extension does not match.
