of all the libraries I have installed on my drives, the only time I have seen ‘Side’ Mics are if there is actually a Side Snare, to the left of the main Snare.
Top and Bottom Mics, the odd Stereo Mic and some effect versions of the said but never a microphone for the sole purpose of capturing the side of the snare.
I am pretty sure this is not something dictated by Toontrack, since every library engineer would make the decisions in the studio.
