OPUS is compatible with third-party Impulse Responses (IRs) in .wav or .aiff format, 16 or 24-bits, 44.1Khz to 96Khz.

Loading Static IRs into OPUS' Internal Memory

To import or remove 3rd-party IRs in OPUS, registration of the device via Torpedo Remote to your Two notes account is required. You cannot import or remove 3rd-party IR's when using Torpedo Remote in Guest mode.

To load an IR file into OPUS’ internal memory, please navigate to the IR Manager window.

Prior to transfer, the IR Manager interface provides some handy options to modify the IR file for the transfer:

• IR length: increasing the IR length will improve the resolution of the Torpedo processing, ultimately resulting in improved accuracy in OPUS’ low-end response. Please note, a 40ms IR will occupy 2 slots in OPUS’ internal memory.
• IR offset: you have access to 3 options that will change the manner in which the IR file will be processed:
  
  1. Min Phase: an internal algorithm in the OPUS architecture will adjust the samples in the file ensuring playback will be in phase with any other IR file (providing you use the same function to transfer all applicable IR's).
  2. Min. IR Latency: the file is cut so there is no silence before the first sample; this can lead to a change in the overall sound of the file but the playback latency will be minimal.
  3. Original: the samples in the file remain untouched. Please be advised that in this instance, you may experience phase cancellation issues with configuring presets with dual IR files.

Some important considerations:

• With 3rd-party files, you will not have access to microphone positioning parameters akin to the DynIR platform.
• It is possible to use IR's that are stored on your computer's hard drive directly without import into the OPUS hardware. When doing so, playback will be limited to Preview mode and only one IR can be used at a time via slot: IR A. Within Preview mode, you will be able to save the associated preset on your computer but not on OPUS. To have full capacities when using IR's, we advise importing the required IR files into OPUS.

Preloading OPUS’ Built-in Memory Card with Static IRs

​​If you’re seeking more IR's than the 512 slots available within OPUS’ internal memory, please use the memory card. Please bear in mind that the memory card is not seen by Torpedo Remote and is only accessible through the pedal itself. First, the memory card has to be mounted. To mount the card, please navigate to the Menu → Global section, and scroll to “Memory Card Mount”. Press ENTER to mount the card. Then, connect OPUS to your computer. OPUS will then be accessible as a regular mass storage device. Copy and paste the IR files you wish to include on the memory card, and when finished, ensure you unmount the memory card by pressing ENTER on OPUS.

The 3rd party IRs loaded on the memory card will then be accessible through the IR Loader mode in the folder entitled “MEMORY CARD”. There are 2 methods to browse the IRs on the memory card:

• By scrolling with the VOLUME/VALUE knob on the FILE location.
• By pressing ENTER on the FILE location to open a view of the waveform of the IR. Press on the MENU knob to go back to the root of the memory card and see all the IR files loaded on the memory card, and browse them.

Please note that only IR files in .wav format and at 48 KHz sample rate are readable from the memory card in OPUS.
