Hey all! I see that Quad Cortex includes various different IR Loaders. But I don’t understand the difference between them.

I believe single indicates single channel for only one IR file, dual for two different IR files, M for mono and ST for stereo.

But looks like single ones has two channels for different IRs. So they are dual?

Lite ones look like real 1 channel IRs.

The lite versions don’t include a room reverb unnecessarily as it takes up more cpu.

I would imagine that mono/stereo refers to the input and single/dual refers to how many irs you can load.
