Whoa, super super cool, what an awesome piece to emulate. Only tried it on a vocal and a piano soft synth, but it sounds really great. Can't wait to try it more.
This may just be my old inadequate mobile rig acting up, but the AAX version (PT 2018.4.317) currently uses almost half again as much CPU as Acustica El Rey. Anyone passingly familiar with Acustica products will know that that doesn't quite add up, haha. Possible bug in the AAX version? VST2 version in Ableton 9.5 is very impressively light by any measure.
