problem with XY pad and effects

[Ferra41]

Hi, I have a problem with the XY pad and the effects, I insert an effect in the xy pad and if I use the mouse the effect starts and remains fixed, if I use a midi controller (akai mini mk2) it only flashes and then disappears, how can I solve it?

my intent is to control the size of the effect via slider

Your midi controller sends note-on + note-off signals. Hence the flash behaviour. I think you need another mode of your controller.

ok, I'll try to see with the other modes, it's just that the problem happens there, with the other buttons everything works
Thx

I couldn't solve it in any way, it always has the same problem, do you know if there is a way to control the effect size from the midi fader?

...do you know if there is a way to control the effect size from the midi fader?

Have a look at this example: https://www.qlcplus.org/forum/viewtopic ... 245#p70245.

Just connect a Fader on your AKAI as External Control to the slider.

this works fine, the problem is that the effect does not stay inserted in the xy pad but you have to hold it down, and consequently I cannot control the size.

you have to hold it down, and consequently I cannot control the size.

Say what? What do you have to hold down for?
Aah - okey -> a midi controller? Does it have sliders? They should stay put. But then again, you cannot 'hold' a slider down.

Try to explain to us what your setup is like. 'Holding down' is like a button, but holding down a button and manipulating another control does mess things up. How do you control the size with a button?

basically i have a xy pad, i control the size with the midi controller faders, and everything works perfectly, i insert an effect as a preset in the xy and assign a button to start it, if i use the mouse and click on it the effect starts and stays active, if i click on the midi controller button the effect starts and stops as soon as i release the button. once my effect is active i can control the size correctly with the faders, but the problem is keeping the effect active from the midi controller (which by clicking on it with the mouse keeps it active until the next click)

Does this only happen with presets in the XY Pad, or do you have the same problem when you use a button from your AKAI as External Control for other Buttons on your VC?

To be sure:
- use a separate Universe for your AKAI (and set it up for Input and FeedBack),
- use an Input Profile for your AKAI.
- do not reuse functions: if the same function you use as preset in your XY Pad also occurs in a solo frame somewhere else on your VC, another active Button/Function might turn your Function Off.
Make a copy of your Function and rename it, to ensure that it is unique.

[Ferra41]

only with presets, if I create a button and insert the effect, everything works correctly, with the only problem of not being able to control the size from the xy pad. I created a project that is completely empty and with only one effect and one xypad to avoid interference, I use the profile that is installed by qlc+ for the akai, with the actual project everything works correctly, the only thing I can't do is that.

I guess this is a bug (if you add Positions as Preset the External Controls work Fine, but for Scenes and EFX's the External Controls only act as a Flash Button).
It is not exclusive for the AKAI APC Mini, my Novation Launchpad (with or without Input Profile) does the same.


There is a workaround however, have a look at this example:

XY Pad with Loopback Buttons.qxw

(72.34 KiB) Downloaded 53 times

Universe 4 is set up for (output to) LoopBack 1 (see Input/Output Tab) and in this Universe 4 there are 8 Channels defined (see Fixtures Tab).

On the Functions tab you will find 8 Sequences (one for each Channel). It is important to know that they are "Run Once" and the Running Time is set "per step".
Each Sequence provides a (short) LOW followed by an (infinite) HIGH.

On the Virtual Console on the XY Pad on the right you will find that the 8 LoopBack Channels are set to act as External Control for the 8 Presets.
On top of this XY Pad you will find a Solo Frame with 8 Buttons (that launch the 8 sequences).

Now attach your buttons from your AKAI as external Control to those Buttons (and once you have tested it), move the Solo Frame upwards (to make it cover the Preset buttons of the XY Pad).


Please Notice that you now also have the option to change size and BackGround Color of the Buttons and use different Character sets, sizes and ForeGround Colors for your Descriptions (Widget Name).

thank you very much, tomorrow I'll look at it carefully and try to understand how to integrate it, and then I'll let you know if I succeeded in my intent

[Ferra41]

the project seems to work fine, i have to try to implement it in mine, but it seems doable. Thanks a lot for the suggestion
