I'm trying to control a slider from VirtualDJ via os2l.

But I couldn't move the slider on VirtualDJ.

I've already succeeded os2l button test.
Can we control sliders using os2l?

I could move a fader on the virtual console of QLC+, but the fader can move only from 0 to 100 though I set this fader's min,max to 0,255.

How can I move this fader from 0 to 255 on the virtual console via os2l from VirtualDJ?

In the case where the fader’s (min,max) was set to (0,67) on the virtual console of QLC+, VDJ could move only the fader on the range 0 to 26...

Midi values (0-127) are half the range of DMX values (0-255) so you have to double (or think double) interpreting midi values.

I think 100:255 is not equal to 127:255=1:2.

That command from VirtualDJ via os2l protocol sends signal as percentage of maximum DMX value(255), but I think QLC+ interprets the signal as DMX value in its own.

I think QLC+ should multiply the param via os2l protocol from VirtualDJ by 2.55 .
(100% * 2.55= 255)
