The software tools within Logic X that I most often use include: NI Komplete (the whole suite and samplers), NI Massive, VPS Metrum (To make kicks), Logic’s ES2, EXS24, Xfer plugins (like LFO Tool), Sylenth1, FabFilter Pro Suite, EW/QL Symphonic Samples, Voxengo SPAN, iZotope Ozone (Just for analysis, not for actual processing).more
Massive improvement from the analyzer section in Logic's Multimeter. Create an account on pluginboutique.com and download this asap (as well as the tons of other free plugins there)! =D
I use the free version of this, and I love it. I use it for mastering, checking for clipping, and just as a visualizer when I want to kick back and listen to my song. It really is awesome that its a free plugin.
