1.Sometimes, when I turn on delay in fx section, audio input in viper is crashed, and work only one chanel (right or left) (the same issue is in the reverb) or not play right and left channel and I must reload plugin.
sounds like same issue(?) what I had in FL. Load Viper, play default sound, load factory bank 2 or 3 "on the fly" and Viper says click and sound goes only in left channel. Right channel output goes red and stays there all the time, but no sound. Already reported this here.
