[Solved] Audio File Processor: no dynamic controls

[Kirane]

Hi there,
I've been learning LMMS via wiki, forums and tutorials in youtube and it has been fantastic on resolving all my questions. Yet this one is resisting me:

Say I want to make a sound that fades in (I rise the vol from 0 to 100%).
I upload the sound to an Audio File Processor (AFP). Then I tie a controller to the volume knob of this AFP.
I see the knob moving based on the properties I give in the controller controls. So far, so good.
But when I play the sound in AFP the volume knob freezes for the duration of the sound, wherever it was sitting when I play the sound (it doesn't matter if I play the sound via piano roll, or by hitting the key or click with the mouse in the little keyboard of AFS). So the volume might be anywhere between 0% and 100%, but it won't change for the duration of the sound.
This is not what I am expecting the controller to do.

Why is the controller freezing while the sound is playing?
If it's always going to freeze, I don't fully understand the purpose of the controller rack.

Can you help me here?

I think you mean an LFO in the controller-rack(?)
-and unfortunately you are correct
LMMS only have pr-time-envelopes. What you want is pr-note-envelopes, but there is no option for that, yet.
To achieve a raise in volume/note in AFP, you need to automate each event.
You can get pr-note envelopes in VSTs
I demonstrate how here in Synth1

OK that is clear, thanks!
