One of my favorite VST plugins to use when trying to find inspiration, is Output's Arcade loop playback plugin. In my opinion, it is by far the best value out of any of the loop subscription sites. Yes, Arcade is subscription based ($10 per month), but you will always have access to any loops that you download and use even if you cancel your subscription (or so they say). They are adding new kits and loops to the site weekly (if not more often).
I also decided to create a new audio visualizer in #Adobe #AfterEffects using mostly stock After Effects plugins, but I did also use Boris FX new #UltraZap plugin mapped to the audio waveform using Red Giant's #Trapcode #SoundKeys.
