Questions regarding Serial.Begin baud.

I am relatively knew to Arduino, and I am having some trouble with a program.

I want to make a midi interface which I can control using a computer (a mac laptop, in my case).

I'm starting out by combining these two tutorials:

http://www.arduino.cc/en/Tutorial/Dimmer

http://itp.nyu.edu/physcomp/Labs/MIDIOutput

My problem is that the two tutorials differ in their baud rates, in the Serial.Begin calls.

Can someone tell me more about these, and if there is a way to 'mix' two together, in order to both read info from computer, and write info to the midi jack?

Thanks very much,

Riley

After a bit of research, I realize I really need dual serial connections.

I need to be able to control serial out (midi) and receive info (computer).

Can anyone suggest how to go about doing this?

You could use a software serial solution, or you could buy the Arduino Mega. Both will give you multiple serial in-/outputs. :)

Thanks very much!

I will research those.

I was wondering, is it possible to change the baud rate during runtime?

Say for instance, I wanted to change the serial rate in order to read an incoming command from the USB port, and then switch to output a midi command?
