hello
I am building custom pad (already done with help of locodog)they are reacting like "ableton" with quantise before next Cue..But my question is about the name of my pad...I want to give the name of the hot_cue (pad1--hotcue 1'name..Pad 2 __hotcue 2 'name') but in the empty text field of Name, no script seems to work...I know that i already talk about this here but I don't find the old threat...
 
if I understand, you want
Pad 1 name: `cue_name 1`
 
or if you wanna have different alternative (name, number, position) depending on cueDisplay setting :
Pad 1 map Name to : `cue_display 1`

ok so..i understand that I don't know what is this character not a " not a '..and when i copy paste your code it works...(but i already tried it with ") OK so it was so simply thanks again locodog
 
It's a backtick [has a few names, you should see it above your tab key]
https://www.computerhope.com/jargon/b/backquot.htm

in vdj script backticks [`] are used in a few places, mostly when dealing with text, it tells vdj to use what is inside two back ticks as a script, and then parse it as text
for example, you set a variable to 6.
set 'myVar' 6
you could give a pad name something like this
myVar is `get_var 'myVar'`

what would be displayed is
myVar is 6

backticks have uses in more advanced script than just text, but the purpose is the same. parsing script,
set 'myVarSquare' `param_multiply "get_var 'myVar'" "get_var 'myVar'"`
it can be a little confusing when you need to use backticks as some param_ modifiers are expecting a script so they don't need backticks, other param_ modifiers might expect a script or a string so backticks are need to indicated we have passed it a script.

It's just one of those that you learn with practice.
 
Hello Friends, excellent forum.
Please can you help me to create a script or command to execute the progressive "Filter" effect, or a curve for increase or decrease Filter sound fx, by clicking a single button or key. Thanks in advance.

As it the trail or route made by the potentiometer or filter knob, but by pressing a single key. May be trailing Filter fx from 30% to 80%.
 
repeat_start 'filterTwist' ? repeat_stop 'filterTwist' : repeat_start 'filterTwist' 33ms -1 & filter 0% ? repeat_stop 'filterTwist' : filter +0.5%

something like that is the most basic way, I have virtualFX that can do it a bit more advanced, from a position, to a position, over a beat duration.
if you want that post in the virtualFX thread and I'll tweak the one I have here.
 
Thank u very much Locodog, this one is very useful. Ok, yes please go ahead, tweak this script like virtualFX thread.

Something to set a range of Filter FX trail, from - to and reverse to -from if possible.
From center 50% to 80% and return 80% to normal 50% automatically by pressing one key. And functional for another sound FX.

Thanx in advanced.

ok I undestand finally ...super clrear thanks again locodog ;)
 
I have an other question : i made a variable called "scale" for the key..scale 0 is major, scale 1 is minor scale 3 Dorian etc...I asked my custom button display the value of the variable (1.2.3 etc) but is this possible to say "name of var scale 0 = "major"...name of var scale 1 = "minor" and display the name in the custom button ? ;)
 
sure, example [I won't give you the exact code, because figuring it out is part of the fun :) ]

script action
toggle test

button name
`var test 1 ? get_text "true" : get_text "false"`

cool i get it :;) ty (again)
 
here is my goal : manage key (different scale) with 16 custom pad (like in jpg) and simultanely can manage key with a slider or pots... I can not just use the action "key" on my slider because of the different scale that i want to use, there is some changement in the "next or previous note"...so I did a script to say when param of slider is between this and that go to Key x(separatly it works well)...the issue is when i want to use slider and pads on the same deck : the slider is master and when i hit my button ,it just make the good key a mili second (like a pitch bend...interesting by the way) and returning to the param of my slider (because of the action "repeat_start_instant 'bars' 30ms " I suppose)..so my question is..is there a method to say "when hit the pad stop repeat "and when i use my slider again the "repeat instant" start again ? i don't if it is clear but by trying to explain i probably advance for a solution ;)))
 
the button is easy, just stop the rsi as part of the script.
repeat_stop 'RSIname'
the slider, nearly as easy - query if the rsi is running at the start, if it is do what you were going to do, if it's not start the rsi and do your thing

repeat_start 'RSIname' ? is running, carry on : not running, start the rsi, carry on

ok i get it with this code
"var "$Scale" 0 ? repeat_start_instant 'KeyFader' 30ms & deck 1 param_smaller 1% ? repeat_stop 'KeyFader' & deck 1 key -12 : repeat_start_instant 'KeyFader' 30ms & deck 1 param_bigger 1% & param_smaller 5% ? repeat_stop 'KeyFader' & deck 1 key -11 : ....."
it works well ;) no need to change on the button :) ty
 
Hey Locodog ! I just have a question. Do you code all inside VDJ or do you use a soft for coding ? if yes, wich one? thanks
 
if I was doing a big remapping I'd use np++, most of the time I'm in vdj.
 
Hi all

USE of BACK TICKs

IIDEEJAYII wrote :
When do I do I need the back ticks on parameter? in this case level is defined by VDJ as value of a volume fader.

Is it advised to use `level` in 

param_greater 50% `level`


since the code below also works without the back ticks
param_greater 50% level



with 2 amazing replies

locodog wrote :
param_greater is expecting 2 things, that could be an actions or values, or a mix
since it is expecting an action it can work with no spaced actions without ` ` so, level, get_level etc will be fine.
however, if there's a space in the action, lets say
effect_slider 'echo' 1
the space will mess things up so you would need to encapsulate ` ` , I believe encapsulate works with " " & ' ' too

param_equal, is slightly different, it is expecting either action, value or a string so, wrapping with " " or ' ' is reserved for strings.
Most of the time if doing a comparison on an action, wrapping the action in ` ` can't hurt there is one exception I'll try remember what it was.
*edit, I was remembering the wrong thing

i try again as post does not appear

`level & param_bigger 0.75 ? get_constant 0 : param_cast int`

backquote only not needed with "param_*' when action is one word only
most other verbs are needing backquotes or ignore them
as locodog said there are "exception" . trial & error only can help


All the above tests and comparisons are only working with scripts and physical sliders but not with custom_sliders
(custom sliders are not real sliders anymore for a while)

so that user slider have to be scripted in a way to make it work correctly
they need a specific variable (each) to handle value, specially using relative scroll, slide & move
(encoders, touchscreen, mouse roll)

set v[INDEX] & param_cast absolute & set v[INDEX] `get_var v[INDEX] & param_bigger 0.0 ? param_bigger 1.0 ? constant 1.0 : get_var v[INDEX] : constant 0.0` & param_add 0 `get_var v[INDEX]` & ...

set v : save the wrong absolute value (not in slider range)
param_cast absolute : convert param for future use
set v `..` : fix correct value for the slider
param_add 0.0 ... : hack to be able to overwrite parameter with correct absolute value and update slider display accordingly
& ... : now parameter is in range [0.0..1.0] and correct absolute value is passed to the script
