Here is my problem :

I use a joystick to drive synthétizers (in reaktor, but I don't think it has an importance). The note is triggered by the trigger of the joystick. It works fine but I don't want that notepitch is changed while I'm moving the joystick once it's triggered. It makes an awful noise to have all those notes triggered when I move the joystick, even 1/10th mm ! So I would like to use only the X axis value output by the joystick when I trigger it and I want to ignore all values sent by X axis while joystick's trigger is on.

Example : here is what is output by the X axis from trigger start to trigger end :

255 256 236 284 124 236 2358 etc I want to use the first value (255) and that's it and ignore all what is output afterwards by the X axis.

Is it clear ?

hi esox,

try this:

[ \ <---output from x axis goes here
|
[t f f]
| [sel 255]
| |
| [0 (
| \
| \
[spigot 1]
|
[ \

I hope that helps.

I don't understand the value 255 into [sel]. The value output will be from 0 to 6535 directly from the joystick, 0 to 127 once converted for midi pirpose.

To say my question another way :

let pass the first X axis value when trigger = -1 and ignore the following one. A kind a spigot that closes right after receiving the first value.

Hi esox!
I don't know what is trigger in your patch. Anyway, I still think that [sel] will do the job for you. It outputs the bang message if the input is the same as the creation argument. You can convert that bang into [0( or [1( for closing or opening the [spigot].

In fact I have no creation argument to provide, it will be always different depending of the position of the X axis when joystick is triggered (whqt I call trigger is the bitton on the joystick usually used to shoot ennemies !).

I posted the patch

umm, so use [spigot]

It seems to work !Thanks, I need to test it in my patch. ANd I also need to take some time to understand why it works.

It works perfectly, thanks ! And I understood how it works. Very easy in fact, but the post difficult things to fond are the easiest ones !
