Kontakt - Script for set the MIDI CC7 volume range

[hellishvictor]

Hi everybody

Ok, the volume range of a instrument can be set when a knob is declared:

Code: Select all

declare ui_knob $example(0,631000,1) {0 dB}

or

Code: Select all

declare ui_knob $example(0,500000,1) {-6.0 dB}

but I like to know if there's a way to replace the value with the help of two switches, putting a variable whose value change when one of the switches is trigger, something like:

Code: Select all

declare ui_knob $example(0,[b]$value[/b],1)

and later on ui_control a if ($b = 1) then $value = 631000 or something like that.

I have done a script hat does something similar, but not totally exact, since the knob start to respond when its half way:

Code: Select all

on init
	make_perfview 
	set_ui_height(2)
	declare $volume

	declare ui_switch $a
    set_text($a,"0.0db")
	$a := 0

	declare ui_switch $b
    set_text($b,"-6.0db")
	$b := 0

	declare ui_knob $MasterVol (0,1000000,1)
	set_knob_unit ($MasterVol,$KNOB_UNIT_DB)
    set_text($MasterVol,"Volume")

	message ("")
end on


{ UI_UPDATE }
on ui_update
$volume := $MasterVol
	if (get_engine_par($ENGINE_PAR_VOLUME,-1,-1,-1) # $volume)
		$volume := get_engine_par($ENGINE_PAR_VOLUME,-1,-1,-1)
	end if

	$MasterVol := _get_engine_par($ENGINE_PAR_VOLUME,-1,-1,-1) {el knob coge el volumen del slider}
	set_knob_label($MasterVol,_get_engine_par_disp($ENGINE_PAR_VOLUME,-1,-1,-1))
end on

{ UI_CONTROL }
on ui_control($a)
	if ($a = 1)
		$b := 0
	end if
end on

on ui_control($b)
	if ($b = 1)
		$a := 0
	end if
end on

on ui_control ($MasterVol)
	if ($a = 1)
		$volume := $MasterVol
		_set_engine_par($ENGINE_PAR_VOLUME,$MasterVol - 369000,-1,-1,-1)  {{0 dB}
		set_knob_label($MasterVol,_get_engine_par_disp($ENGINE_PAR_VOLUME,-1,-1,-1))
	end if

	if ($b = 1)
		$volume := $MasterVol
		_set_engine_par($ENGINE_PAR_VOLUME,$MasterVol - 500000,-1,-1,-1)  {-6.0 dB}
		set_knob_label($MasterVol,_get_engine_par_disp($ENGINE_PAR_VOLUME,-1,-1,-1))
	end if

	if ($a = 0 and $b = 0)
		$volume := $MasterVol
		_set_engine_par($ENGINE_PAR_VOLUME,$MasterVol,-1,-1,-1)
		set_knob_label($MasterVol,_get_engine_par_disp($ENGINE_PAR_VOLUME,-1,-1,-1))
	end if

end on

Any help will be appreciated.
Cheers

This is unnecessary since any user can set the CC7 range for themselves in Instrument Options.
