EDIT: I'm an idiot. It was the noise knob. Please disregard. lol
So I've finally found some time to start poking around at my work in progress and noticed a hiss even with playback stopped. I did some hunting around for the culprit (turned off any armed tracks, input echo, a/b'd various PC power buttons on busses, etc). Turns out it was coming from the instance of the new Tape Sim I had inserted to my drum bus. It is definitely making the drums sound pretty awesome but I find it odd that it is creating hiss even with playback stopped and no live signal feeding it.
Is this to be expected? If so I'm a little concerned because although the sim sounds great it's an awful lot of hiss for one instance (especially with no playback). It may be possible other effects are contributing but the hiss disappears immediately when disabling the TS.
Just trying to get an idea of what I'm dealing with here. I recall the old Cakewalk plugin tape sim had a hiss/noise control that would add hiss as desired. Perhaps there is a similar control where I can remove the hiss without removing the awesome sauce with the PC version.
Cheers and thanks.
