Xfer Serum, support from the dev in 1-2 days. Pluginboutigue, support in 1-2 days. Soundspot, support in 1-2 days. Cytomic, reply in 1-2 days Steinberg, support reply in 1-2 weeks, that is just way too slow.
I really hope you people at Steinberg would answer faster to support requests. DAW is the major thing when producing music. I can live with VST not working correctly, but when my DAW is acting up, i really want fast support and no, REINSTALLING everything is not the answer I need. I can do that myself.
