Noticed a couple of crash reports, some bugs, some talk - over at KVR Audio forums. Maybe they are new users posting and don’t know about reporting any troubles through MySteinberg:-
Steinberg Spectralayers - Hosts & Applications (Sequencers, DAWs, Audio Editors, etc.) Forum - KVR Audio - start from page 5 onwards.
(a SpectraLayers person, Bill Evans, has posted in that thread too - so maybe you are/he is already aware…)
This post is purely for your info. Please delete as necessary.
PS:- Exciting product - looking forward to demoing this when it becomes available…!
