Free SpaceBlender from SoundToys
Might be good for sound design... I just gave a quick test run. It is quite reminiscent of Valhalla Shimmer, though thicker on the Reverb department. Applied sparingly it sounds pretty cool. That is, everything set between 8 and 10 on the clock, including Mix. I just tried it on a vocal. it's definitely expressive. Also reminiscent of the other free ones from Valhalla. https://forms.soundtoys.com/?utm_source=Master+List&utm_campaign=09a6e837ed-EMAIL_CAMPAIGN_2018_11_12_11_00_COPY_02&utm_medium=email&utm_term=0_bbd3e23605-09a6e837ed-88926312&mc_cid=09a6e837ed&mc_eid=44c544bbd8#/free-spaceblender
