Question about leds & push buttons

Design Concepts
1

Hello,

I’m ready with my controller design but before I ‘give birth’ to this piece of hardware I do have a question about the behaviour of leds combined with buttons.

My design does have leds ‘chained’ with each other.

First of all I use ON buttons when pushed they are ON. When released they return in the OFF position.

Can the following be achived:

If button 1 is pressed led 1 lights up and stays ON even when I release button 1.

Is this possible even when I use the push buttons as described above?

Now when I  press button 3 with led 1 still ON led 1 has to  go out and led 3 has to light up.

When I press button 2 with led 3 still ON led 3 has to go out and led 2 has to light up…etc

So even when I use a momentary buttons I want the leds act like they are triggered by on-off switches.

Is it possible to ‘chain’ the leds in a row? How do you design this within MIOS?

I hope you get an idea.

Can someone help me out with this.

Thanx  ;D

well, maybe if you described where you want to use it, …

The leds can react to midi messages sent by the program instead of the button position too.

So if your program has midi transmit for events, like cubase sx…

My program only receives midi…it doesn’t send any midi messages.

The only thing I want to achieve is when I push a button I want 2 see on my midibox which button I did  push the last time.

The buttons on my midibox correspond with the ones used in my prog. A few of them are ‘chained’ with each other. Only one of them can be selected at a time.

So when I switch from button to button on my midibox the corresponding leds have to ‘follow’ the buttons I push.

@ this moment of writing I think this could easily been archieved without the use a a midi protocol. It’ just plain electronica…a parallel led-chain connected with the buttons…
