Topic: Bug Report - Echo Out Effect
First of all, congratulations on the new version.

Issue:
The Echo Out effect parameters become non-responsive after activation.

Steps to reproduce:

Load a track on a deck

Activate Echo Out

Attempt to change Length → control does not respond

Attempt to change Reverb → control does not respond

Change Color → value changes but cannot be reverted

Expected behavior:
All parameters (Length, Reverb, Color) should remain adjustable in real time after the effect is activated.

Actual behavior:

Length and Reverb cannot be changed once the effect is active

Color cannot be returned to a previous value after being modified

Impact:
This breaks live DJ workflow. Echo-type effects are designed to be activated first and shaped in real time, not pre-configured before activation.

Additional context:
I am currently transitioning from Traktor to VirtualDJ. In Traktor, Echo-style effects remain fully adjustable after activation, which is standard behavior in professional DJ software.

Please address this issue, as the current behavior limits real-world performance use.

The length for Echo Out is intentionally fixed when starting the effect, so that loading a new song on the same deck with a different bpm does not affect the outgoing trail of the previous song.

Color and reverb should be adjustable while the effect is running, but with color keep in mind that once a part has been filtered you can't bring those frequencies back anymore.
