QL+ from REAPER DMX Control

gistfile1.txt

Piste MIDI avec MIDI Control Output
MIDI FX capable of MIDI CC Out, like ReaControl MIDI
Check Channel and CC number

In QL+
LoopBe as Input of the universe. Not output
Launch LoopBe
Add Profile in In/Out for loopbe
Add Slider
On virtual console
Check input of the slider. Should match slider above.
Then press Play button on the top right

Now changing value of ReaControl MIDI should change value of the slider.

Tip: set track in REC, or deactivate anticipative FX (or set it to 0) for realtime feedback.
