Hold Button knob

[Ariajazz]

Is there any way to create a button (touch screen) that will increase or decrease values of a knob or fader by pressing and hold on it?

Something like this work, play with the width parameter of the ramp to adjust sensibility

[Ariajazz]

Thanks Nay... it works perfectly.

One little problem: when I press and hold the button and reaches the top it does not stop, instead it jumps to the minimum value (0). The same happens when decreasing, it jumps to the max value. How can this be fixed?

Thanks in advance.

[Ariajazz]

Does anybody know?

You gotta think these things thru logically...

The first step is to figure out the rule. You ONLY want the button to increment the fader if the fader value < the max, correct? That's the rule.

So there are probably many ways to do this, but here is one way:
Add an AND logical module between the button & the Pass module above
Add a 'not equal' (<>) logical module after the Fader

Fader value => Not Equal A inlet
Fader max => Not Equal B inlet
Button mouse down => AND A inlet
Not Equal out => AND B inlet
AND out => Pass Flow pass inlet

and, of course, remove the existing Button mouse down connection to the Pass Flow pass inlet

As long as the fader value <> max, there will be a '1', or TRUE coming from the Not Equal <> module.
The AND between the button & the fader will thus only work when this is so. When the fader value = max, the Not Equal will return FALSE, or 0, and the Pass will withhold the flow.

Hope this helps,

you can use the "incrementor stop" module I made

check the Oli_Lab module pack on the addon page

cheers.

I tried this several times and checked if i was doing something wrong but did not work. Could you please show a diagram with the modules involved in the patch?

Use my module !

Use my module !

I'm using USINE STAGE. I downloaded your modules pack but I cannot get them seen by USINE STAGE. 5.80. OK with Hollyhock but don't know how to use it

The above shows the technique I described above.

A couple of notes:
- The clock was a little more versatile, you can adjust the speed by changing the interval
- Note that since it will keep incrementing whenever the curr value <> the max value, you do have to pay careful attention to some of the fader values. I set the Fader "inc/dec val" to 1 and the Fader "precision" to integer. That way you know you won't get a value of 127.35 or smoething like that, which will just cause another cycle thru from min to max.

Hope this makes sense...

[Ariajazz]

Thanks Shawnb. I'll try it right away.

OK this is what's happening. The fader (-50/12 dB) has two controls INC and DEC. it works perfectly when set to integer and inc/dec val=1 but I need to have with at least one decimal, which I did ( X.X and 0.1 inc dec val). In this case it stops at 12 but it does not at -50. I'm checking out what could be wrong but I don't find anything

If you need one decimal value, then your inc/dec must be 0.1 and your fader precision must be x.x.

If this doesn't work, we may need to do the math & range check completely outside of the fader control. Then we can clip it & provide full control PRIOR to setting the fader value.

It is exactly what I did but I wonder why it does not work for DECREASING. It does the job for INCREASING the values as it stops at the maximum value.

Here is the patch

Fader INC/DEC value does not alow to be set at 0.1 instead it appears as 0.100000001490116. weirdly it allows to be set at 0.5 all other decimals appear with a long series of digits. Is there any way to solve this?

Attached is an image & an example of a slightly different approach. I didn't like the "feel" of the increments/decrements, it felt like the speed was out of control.

So... On this patch...
- a click on the left half of the button increments or decrements by your inc/dec value
- a double-click on the left half of the button increments or decrements by a bunch of your inc/dec values
- holding the right half of the button scrolls smoothly

Try it out!

Very helpfull, thanks a lot. Although y created a similar patch that suites my needs.
