IR loaders

IMPULSE RESPONSE LOADERS

LECAB 2 - NADIR - Mix IR 2

A cabinet simulator is made of 2 things:
- An IR loader, which is a plugin with various options,
- An IR, which is an audio file. This audio file is the sound print of the gear you wish to emulate. The IR is what will allow you to simulate the sound of the chosen cabinet, so its quality is essential if you want a good result. In fact, your cabinet simulator is merely an IR loader. Then you choose what type of cabinet you want to emulate.

How to use it?
That's simple. You pick one of the plugins below, for example LeCab 2, then you place it after your amplifier simulator, and you load an IR in it.

The cabinet simulators you can download below are provided without any IRs, so you have to find or buy them and load them in your cab simulator.
You may download free IRs, below, find some on the Internet (free or not), or make them yourself...

LECAB 2

LePou gives us access to no less than 6 IR slots simultaneously! For each one of them, you can invert the phase if needed, set the delay time, configure a lowpass and a highpass filter, and of course you can set the pan and volume. You can also solo each slot, link the loaded IRs of 2 slots (but other controls remain independant). You can also control the latency. The lower it is, the more CPU-consuming it becomes and vice-versa. Last but not least, the graphic interface is nice and clean!

But why would I use 6 cabs at the same time?
Well, with only one guitar take, you can get six differents sounds, which allows you to get a bigger sound, or to obtain sounds that are impossible to achieve with only one cab, by using various IRs, modifying the panning or the other settings... You don't have to use all six available slots, but if you wish to experiment, you can. I usually use two IRs of the same cab but with different microphones, so it will simulate the sound of a real cab recorded with two microphones. And if I want a bigger sound, I can add more IRs. Very convenient.

One nice improvement over the previous version of the plugin, it now remembers the IRs' folders of origin. So you don't need to scratch your head anymore if you don't remember what IR was used when the IR name is not explicit.

NADIR (web site)

NadIR is a free plugin from Ignite Amps. This Italian company makes and sells real guitar amplifiers, and they develop excellent amp simulations (demos on this page). NadIR allows you to load an IR in either available slots and modify the settings as you see fit. You can pick a mono, double mono or stereo signal, set the processing quality depending on your computer ressources, use high-pass and low-pass filters, set the delay and panning of your IRs.

Hello.

So how can I contact LePou?
The latest X64 version of Legion has a bug where the Drive amount jumps when changing from green/red channels. The knob doesn't jump, but you can hear the drive amount jump when tweaking a little bit, so who knows what the default or chosen sound is being used whenever?
Also similar problems with the Engl as well. The old V 1.01 x86 32 bit version of Legion works perfectly however. (but the newer 64 bit version does sound a bit better, sadly).

Has you or anyone else noticed this?
I want to contact him for a way to fix these plugin bugs.

Hello,
To my knowledge, Lepou has not been active for years in the simulation community. I think he has completely given up by lack of time and motivation. So I doubt he'll be willing to fix any bugs, and I have no idea how to contact him.

Juste pour t'encourager et te féliciter pour ton travail. Bonne source d'informations.
J'ai écouté en partie ta musique : il y a un monde entre 2008 et 2020, non pas concernant les titres que j'aime bien mais concernant leur réalisation. 2020 >>> 2008 à mon humble avis.
Le travail et la persévérance paient !
Bravo.

Hello,
I would like to config my Schuffham S-Gear 2 but I don't know how to do.
I have Logic Pro X.6.2 with S-Gear plugin
I found your website and I ask myself what does it means in the folder Schuffham S-Gear 2.
I don't understand what you have writing like in this exemple : Guitar on the left:
1 impulse of baffle Marshall 1960A (loudspeaker: G12M) through a microphone Neumann U67 in Cap Edge position, at a distance of 2 inches (5 cm). Stereo panning: 100% left.
1 impulse of baffle Marshall 1960A (loudspeaker: G12M) through a microphone Neumann U87 in Cap Edge position, at a distance of 4 inches (10 cm). Stereo panning: 100% left.
How can I find the same sound as you ? How can I do to config my own S-Gear with these parameters ? What does it means ?
Sorry for my English ;) I’m French !
You can answer me directly on my email address.
Thanks in advance.
Jimmy

Hi Grebz,
I don't know if you read these... but I was wondering if your Lepou plugins are x32 or x64? Thanks for all the great stuff on here!

Hello, thanks for visiting my website. They're x64.
