[PD] midi button logic problem

Hi all, I have the following problem and I was wandering if somemody here could help.

For a project I am working on I use a MIDI controller(Peavy Studiomix ) wth faders buttons and knobs. I want to use the buttons as toggles. The problem is that pressing and realesing the button will send 4 messages like that:

print: 2500 127 print: 2500 127 print: 2500 0 print: 2500 0 That means that when I realese the button it will return to its previous value(0) This is not the behaviour I am looking for . What I want is each time I press the button to change state and stay there.

I am also confused by the fact that it it sending its message twice. I think that is something to do with that particular hardware.

Please enlighten me!
