Once the signal is "in the box" and feeding a track in your DAW, the first insert you need to assign to it is a power amp simulation. Only recommended for recording applications - in this case, disable all cabinet simulation within your patch, and load the impulse response in a convolution reverb plugin assigned to the track insert that your modeler is routed to in your DAW session, or on a bus that track is being sent to.Ĭonnect your electric guitar/bass to a preamp and into your conversion interface through the appropriate input. Load/insert the impulse resonse of your choice into a cabinet slot via your platform's editor/configuration interface, and select that slot within the cabinet block/section of your patch. If you are unaware if/how you can load IR's into your host of choice, please see the documentation for that product provided by the respective developer.Īgain, there are two primary methods of application here:Ĭonnect your electric guitar/bass to the input of your amp modeler. If the convolution reverb host has a "Wet/Dry" mix knob, setting it to 100% wet will force all of the sound through the cab/speaker IR, and is the desired setting in most applications. You can load the impulse response file(s) either (a) through the convolution reverb engine built into the virtual amp sim plugin (if it is capable of loading external files), or (b) by disabling the cab/speaker simulation in the virtual amp sim plugin and placing a convolution reverb plugin instance after the virtual amp sim plugin either on the same track or on a bus that the track is being sent to. Get your instrument "in the box" as mentioned above, but now you will need to launch the virtual amp sim plugin on the audio track that you are capturing the instrument on, or on a bus that the instrument track is being sent to. Simply navigate to the cab/speaker simulation portion of the host and search for a button that will allow you to open external. Once you are able to get your instrument's output "in the box", you will need to launch a standalone amp sim application/program that has a convolution reverb engine capable of loading/importing external impulse response files. There are two primary methods of application here:Ĭonnect your electric guitar/bass to a DI/Mic Pre then to analog to a digital conversion interface (line-in of sound card, firewire/usb interface, etc) or into the instrument-in section of an all inclusive or proprietary interface. What are the most common ways to use impulse response files? Hence the informal nickname "cabs" that can be seen used amongst the user community when referring to such files.Īdditional information on how to USE the impulse responses offered on the OwnHammer site can be found in the Tutorials section of the website. The data they capture representats the cabinet, the speaker, the microhpone/microphone placement/multi-microphone mix, and the outboard recording equipment (mic preamp) all the way back to the recorded digital audio of the signal path. In the context of how they are primarily implemented and sold on the OwnHammer website, these systems are mic'd up guitar and bass cabinets/speakers. These files are in a format that can then be read, interpretted, and applied by software containing a convolution reverb algorithm. I probably didn't draw everything correctly - this is my first try at drawing a circuit.Impulse responses are small wave audio (.wav) files that contain linear measurement data consisting of the frequency response, phase response, and reverberation decay of a measured system. Here's a drawing of what I think I've done. I got something backwards because I turn the knob to the left and it is the same as turning up the drive and to the right turns it down. HUGE PLUS - there is NO pause between gain settings like there is with the FAV switch on the Iridium! Very similar to a boost pedal or a second channel. Now I can switch it on and control the sweep of the drive knob and switch it off to return to a lower drive setting. I looked up an expression pedal schematic to run the TRS off of a stereo jack. I used a 3pdt switch (because that's what I had). The manual explains programing the expression pedal. I don't have an expression pedal but I've got plenty of spare parts laying around. I'm interested in creating a switchable notch in the drive knob. The manual says that I can control the sweep of various knobs with an expression pedal. I picked up a Strymon Iridium and have been enjoying the fantastic sounds but was interested in the expression pedal functionality.
