Hi Peter,

Pro-MB's attack and release controls are indeed a little different than your usual millisecond display which you'll see on most plug-ins. The reason for this is that Pro-MB's attack and release is highly program dependant, so reflecting a fixed time value wouldn't make much sense. You can think of the attack and release controls as fast near 0% and slow, nearing a 100%.

Hey Maarten,

program-dependent how? How do the attack and release times depend on the signal?

Thanks

The attack and release times differ on the program, for example fast release times in the low end are not as fast as a fast release time in the high end.

Thanks! Why is this better than letting the user set attack and release times in milliseconds?

It will give you a better sounding result, especially on bands with a wider frequency range.

Hi there!

I hear what you are saying on sound quality - but it sure would nice to at least have the timing/millisecond functionality when using sidechain mode. I use Pro-MB in almost every session now for multiband sidechain, especially on the low end, and it can be so hard to determine what my attack and release settings are doing to the ducking when displayed in percentage.

Hi Jon,

Whether you're using internal or external sidechain, the timings are still program dependent. I'm afraid we simply can't give any hard numbers.

What does the attack/release time % mean in fabfilter pro mb?
For example, if the specific frequency is 100Hz, the safe attack time is 1/100(hz) = 0.01s = 10ms (or more).
In this case, 100% attack time is 10ms, 100% of 10ms is 10ms, 50% is 5ms, and is it a multiplication factor to the appropriate attack time?

The percentages are not linked to an actual value. There is a default attack and release time that is program dependent. It depends on the frequency, the input signal, etc. the attack and release control basically act faster (1-50%) or slower (51-100%) than this setting depending on where you set the controls.
