What’s the deal with “Match (m)” Acoustic IRs?

These have simply been passed through a post-processing algorithm in order to generate a more balanced tone. In contrast, you may find that the non-Match files are a little bass-heavy and as such we advise using OPUS’ EQ to balance and enhance your tone. In addition, we also advise trialling with a blend of your raw DI tone and the non-Matched Acoustic IRs for best results - more info on this below.

Loading an IR via Torpedo Remote

To load a static Impulse response (be it an Acoustic Impulse response or one captured from a traditional guitar cabinet) simply navigate to the IR loader tab in Torpedo Remote and select up to two files to load onto either of the IR Slots (IR A and IR B). You can then use the IR A and IR B channel controls to refine the blend of your IRs within the context of your OPUS preset.

Blending an Acoustic IR with your Dry DI Signal in Torpedo Remote

In some instances you may want to blend an IR affected signal with the natural sound of your DI’d acoustic guitar. In order to action this, simply Bypass (the “B” switch situated within the IR A or IR B mixer pane) to route your dry signal through the IR Loader processing block. By using the channel faders on either IR A or IR B, a mix of your dry and wet signal can be achieved. Please note, this bypass processing simply removes any IR processing on your source signal; any processing outside of the IR processing blocks will still be applied to your dry signal including TSM Pre- and Power-amp emulation and OPUS’ suite of Post FX. In order to fuse a full OPUS-processed signal chain with an unaffected dry signal, we recommend using the LINE OUT ROUTING facilities to send Dry and Wet Signals separately to a suitable source (i.e. a mixer or Audio interface) where a resultant Dry/Wet mix can be processed.
