I'm trying to determine precise millisecond values for instruments' volume envelope knob values. For example, the release knob can take a value between 0 and 2. Zero is easy to calculate, however, at the other end, I hoped a value of 2 would equal two seconds, but after trying it out, it's much, much longer than two seconds. What unit do those knob values correspond to? Is there a simple way to calculate the number of milliseconds a knob value correspond to?

I'm trying to determine precise millisecond values for instruments' volume envelope knob values.

By chance i was working on that code yesterday :p. All dials has their own increment factor
For envelope-release it is 0.001 -one ms
But how to measure that..?
First A Pure release would a span from a < 1. ms initiation event and a measurement of the existence of audible output, over the span of 2 secd.
That is only possible with some serious lab equipment.
But..
Secondly At what volume?
The decrease in output would be depending of volume, waveshape, overtones, and and and....
Only a sine signal at a fixed volume-testmark, would make sense
I dont think you need to have these things 'dialled in' as known values of ms. It more about using what sounds 'good'
