Amp XY/preset change fade-in: unnecessarily long?

    Is there a reason the amp block has to do a fade-in lasting over 100 ms on XY or preset changes? This makes the next note sound very weak when played around the start of the fade-in. Is it possible the fade-in could be reduced to ~10 ms?

    Bump. Any word on this?

    Can this be fixed? Why is the fade-in so long? It's actually more like 150 ms, although it's pretty close to maximum level by 100 ms.

    Bump. Is a programming error making this fade-in 10x the intended length?

    Don't see why it couldn't be reduced to 10 ms without a pop, at least looking at that waveform. 100 ms is an age; are you sure your time scale is right (I'm sure it is, but I had to ask). I estimate a 150 Hz signal?

    I'm sure it was correct. Here's another with project time (seconds) visible.

    I also think the fades should be linear instead of these log curves. The fade out creates audible pops sometimes. It would be fine if linear at the current length (15 ms) but the log curve starts fading at a rate that would end up being around a 2 ms linear curve.

    Linear fades sound weird. Not that the Axe-FX’s very long gap sounds fine though.

    In what scenario? For a 10-15 ms fade all I notice is there's less of a pop with linear. I get that linear fades don't seem as nice for something like a song fade-out.

    All scenarios, I would say. However, non-linear fades can also be short. There’s nothing that dictates that they should be 100 ms.

    Do the fades on one of these gaps (the short ~30 ms ones) sound weird to you? Can you tell which is linear without looking at the waveform?

    6 months later... Why no response, FAS?

    Would a faster amp fade be as simple as changing a value or two in the code?
