chord pad

yall

Hello family ;)
I would like to integrate in my plugin, a kind of pad which would allow to directly play a whole bunch of chords.
so for now I'm using (if (value)
{
Synth.playNote (87, 64);
Synth.playNote (94, 64);
}
else
Engine.allNotesOff (); )

everything works very well but ... according to my calculations I would like to create
12 major pad
12 minor pad
12 pad 5 th
12 pad 7 th

making a total of 48 buttons and as many chord combinations.
Is there not an easier way than to write everything manually?
moreover, I already have a project which is quite big, won't adding 48 buttons make my plugin row too much?
or is it possible for example to create 12 pad, and to assign directly via a list the chords for each pad? I like things that offer ready-made chords but I'm already sweating at the idea of writing everything ^^

@yall - well you know the "shape" of each chord "type" (e.g. Major = 0,4,7) so all you need do is have two drop down menus - 1 with the chord types (Major, Minor etc.) and one with the root note (C2,C#2,D2 etc..) and you can work out the correct midi note numbers...

yall

@Lindon I will do like that I think. is it possible to create 2 additional buttons (octave + and octoave -)? or do I have to write the chords over their entire octave?

Lindon

@yall no you could have 3 drop downs:

chord "shape"
root note
octave

yall

@Lindon oh my god, this is going to be really long all this ^^

Lindon

@yall why its pretty simple logic:

Work out the midi note number for C in the octave selected(e.g. Octave = 1, then C= 60)
Workout the addition you need for the root note selected (c=0,c#=1, D=2, d#=3 etc. etc.)

Work out your required midi notes for the shape selected(e.g. Major = 0,4,7)

so if the user selects D major in Octave 1 then

start point = 60 (the value of C in Octave 1)
root offset = 2 ( the distance from the start point of the selected root note)

Major chord notes are :
0, so this will be 60+2+0 = 62
4, so this will be 60+2+4 = 66
7, so this will be 60+2+7 = 69

..done..

Why do you need buttons, just use the keyboard. User selects major and clicks C they get a C major chord :)

yall

@Lindon @d-healey I would like the user to be directly a pad and not just the keyboard. (this is the fashion for pads ^^).
I have fully understood how to create the chords I recreated a table which groups each note by chord to go faster. I expressed myself badly I think, I want the user to be able to play directly on the pad of chords maj min ... but without going to look in a list (which is not practical for those who want to play live by example).
So yes ultimately it makes me well 48 buttons (12 notes x 4 chords).
that's why I'm telling you that it's a lot of lines of code ^^

yall

suddenly, create 2 button octave + or - I should write 144 buttons ^^

@yall please re-create this :) Casio PT30 was my first keyboard. Learned chords that way
Still having it

d.healey

@yall Do not use buttons. You can do this with a single panel. Watch my live stream video where I started creating a million buttons and Christoph popped in with some script to do it with a single panel :p

Around 1:43

@hisefilo when i will have finished this. I will drop the script here;)

@hisefilo

@d-healey @Lindon
So I just spent 2 hours writing everything. ^^ I tried the method with a panel but I got lost on the way. It is true that so many buttons can become restrictive but as I really wanted to have PADS I am quite happy with the result. (the pads change color on impulse).
for those who want it, I just put down the snippet of the scales major minor 5th min / maj.
if my work can help some it is with pleasure ^^

@hisefilo wow, that's what I'm talking about

d.healey

That is some ugly code :D But it gets the job done!

ustk

@yall That is cool you found a way to make it work! :)
Now you should definitely find a way to make the 1255 lines of code doing the same thing in 50 lines ;)

yall

@d-healey indeed it's the ugliest code I've ever done and still I wanted to do + but my eyes and brains are mush ^^ @ustk if you have something to offer me I m taker. :)

d.healey

@yall The best thing I can offer - https://docs.hise.audio/ - read everything 10 times and do all examples, follow all of the linked javascript tutorials and complete all of the exercises and examples. Repeat this for 5 years :D there is no shortcut.

yall

@d-healey I am only 1 years old. It's already not bad I have to work on adding an automatic button as in the example of your video above. I could reduce the code already with this. I have 48 line from constvar.button ..... It is at the level of the reminders that I have to work. I have already greatly reduced my plugin from 90MB to 8MB by resizing the images, by shortening the codes. but I haven't finished. :)
