This section of the tutorials will provide information on the file formats and impulse response importing procedures for Line 6 HX era hardware and software.



IR File Type Overview



All Helix and POD Go family products accept wave audio (.wav) impulse response files directly, as well as their proprietary IR format (.hir) for products purchased from their online Marketplace web store.



IR File Loading Procedure



Within Helix Native, HX Edit, POD Go Edit, etc, typically to the left hand side is where the IR bank is located. Look for and select a tab that says "IRs", "Impulses", etc. The slot list that populates below is where you will import and organize .wav and/or .hir impulse response files.

From here, the following are actions that can be taken to import .wav and/or .hir impulse response files into an IR bank slot:

[1] Drag and Drop

From a file explorer window, simply drag and drop either .wav or .hir impulse response files into a certain slot.

[2] Right Click > Import

In any slot, right click and then select "Import", then find the IR file you wish to load.

[3] UI Import

First, select the slot you would like to import an IR into, then select "Import" at the top of the slot list to browse to an IR file you would like to load into that slot.



Accessing Your Imported IR(s)



After importing IR files to IR slots, to access them you need to place an "IR" block in the signal chain somewhere after the amp block. Please note that the "Cab" block is not the same and only contains Line 6's stock cabinets. If your patch has the available DSP, it is recommended to use the higher resolution "IR 2048" loader.



Tip for Multiple IR Blocks



If mixing IR's in the Helix signal chain via loading multiple IR blocks, make sure you have them on the same processor path (there are two in the UI, the top line, and the bottom line). If mixing IR's on separate processor paths, you run the very likely possibility of the computations not being made in the same cycle, thus one will happen before the other, and the time of flight will not be the same for the two cabinets, resulting in an out of phase state.
