The Loopback plugin routes QLC+ DMX output back as input, enabling Scenes to control Virtual Console sliders

The Loopback plugin feeds a QLC+ universe’s output back as input, allowing Scenes (which can only set DMX values) to indirectly control Virtual Console widgets accepting DMX input. Procedure: patch U1 output on Loopback, set slider’s input from Loopback U2, add a dimmer channel in U1 at the slider’s control address with LTP behaviour (so releasing the button doesn’t zero the slider), create Scenes with target values, and add Scene-triggering buttons. Fade times on Scenes propagate naturally through the Loopback path.

Examples

A ‘half intensity’ button: a Scene sets channel 14 of U1 to 127; Loopback U2 input drives slider 14 to 50%, LTP holds that level after the button releases.

Assessment

Why must the Loopback-driven channel be set to LTP? What is the signal path from a button press to a slider movement using the Loopback plugin?
