So I’ve just finished an update for both sets. Same thing is added to both. Each set has a stereo and a mono plate. The stereo plate in each set got additional variations such as a stereo swap version, a mono version that uses the sampled left channel impulses for both channels, one that does the same but using the right channel impulses, and another that uses a mono mix of both left and right sampled impulses mixed together for both channels which is a bit thicker than the other mono versions.
These aren’t something that can be obtained easily in your daw with channel routing.
It might seem like it would be easy but it’s not, especially for the mono mix version. These are also more practical and convenient than using complicated mixing. They provide you with more, slightly different sounding (from the main stereo programs they are based off of) options for using in your mixes, and you may find that you prefer one of these alternate versions in some cases, if you try them out!
