hi alistair_blunt,

Thanks for the replay and advices!
For me its better to use pduino since my poor knowlage of pd programing. sorry for that.

BTW I put [change] out and set [sel 1]. 60 is a message.
Still there are some sound comes, when I release a switch...
Maybe the reason by bad soldering on hardware?

thanks

Pd 0.43.4 -extended
Pduino-0.5
Arduino
Ableton Live 8.1.4
mac os10.7.2

hi Ive been making a midi controller using an arduino.
I set a push switch to digital input on Arduino and write on pd like this.

[change]

[select 1]

[60]

[makenote 80 500]

[noteout 1]

Then a sound will come when I push a switch to send a signal. The switch has on/off. But sometimes a sound will also come when I release a switch... I thought to put [select 1] is enough but it doesn't work properly.
Please give any advices.
thanks
