Thanks Augment, I have downloaded a demo version of Audio Damages-‘Mu-Tron bi phase’ -Phase 3 Vst but the time is so limited not got much out of it.
I also downloaded a free version of a Twin phaser by SaschArt and used that in Fruity Loops to mangle drums, also Blue Cat do a good Stereo Phaser. Unfortunately not got much out of Frozen Wasteland ‘Just a Phaser’, it is so much more than the name suggests but I can’t make it work, my fault not Eric’s. I got closest to it using 2 XFX Filters in Phase mode.
True I love guitar pedal emulations in VCV Rack, so many crazy pedals out there to do!
