I am sending a value of 0 and 1 toward a midi ctlout. When my button is pressed down, it sends 1, when it is up, it sends 0.

I want this to instead alternate values so that when pressed down it sends 1, when let go, it stays at 1, when pressing again it sends 0, when letting go it stays at 0..

any indeas?

thanks!!

Not. That's what you want.

not 1 = 0
not 0 = 1

There isn't a [not] in Pd , but there's many ways to do it.

[== 0] may be the most efficient and robust.

that's a lot of nots!!

[sel 1]

[f ] x [+ 1]

[mod 2]

And a latch ... reading the OP again I think you also want a latch to hold up the momentary switch value. There's a few ways of doing that too. Anyone got a very simple latch solution?

(or you can use a toggle gui object, which will use slightly more cpu)

Have fun & do a nice performance protman...

One more [not] could be [< 1], since

0<1 == 1
1<1 == 0
