I use MEqualizer for the everyday stuff that I use an EQ for, like attenuating honk frequencies in vocal and instrument tracks, highpasses, and so forth. It's my go-to EQ that just winds up on every track. Its soft saturation knob is my favorite secret weapon "betterizer" that I hope people continue to ignore whenever I mention it in forum posts.
I bought a license for MDynamicEQ recently and have used it so far to tame ride cymbal stick pings. I imagine that I will find further uses for it. I wanted a dynamic EQ to have in my bag of tricks, wanted to learn how to use one, and as a Meldamoonie, there was only one plug-in house to consider.
It was while using MDynamicEQ that I finally figured out what the Harmonics buttons do on Meldaproduction's EQ's, and as usual, was bowled over by how much hidden power had been lurking in the EQ I had been working with for years. I do find the documentation hard to follow, especially for the Free Bundle.
Of course, cymbals and percussion in general throw off harmonics, so the Harmonics buttons were my friends on that task.
I and probably many others would appreciate a post (or video) containg all the insights you had.
