What's the effect of lowering prog rate from 2ms to 1.5 or 1ms, in Nebula Reverb? More clamping? Does it have any potential negative side effects such as increased cpu usage or decreased kernel length? Is it better to leave it alone?
Deppends if you are using or not TIMED in KERN page!
18.1. Envelope follower in Nebula
An envelope detector is sometimes referred to as an envelope follower in musical environments. It is still used to detect the amplitude variations of an incoming signal to produce a control signal that resembles those variations. Nebula use an envelope follower to translate incoming amplitude audio signal into a value that help to select the correct kernel that will process the incoming signal with the correct filter but this filter has a length that is more than one sample that is the reason that Nebula or any signal modeling processor can emulate correctly a peak limiter with out introduce audible distortion.
