I have not used the Arduinos for a year and have not looked into the new Arduino 1.01.
In the past I have used MIDI send for various projects. I have written the code so that after I send note on I use delay() to set the length of the note. This however causes Arduino to wait while on delay so not other commands could be sent.
I wonder if there is a better way to send note on/note off so while  we wait for the note off other notes could be sent?
Like I play note on Channel 1 duration - delay(100) - and I could send a note on channel 2; then note off on channel 1 and so on.

Look for blink without delay tutorial.

That is where you are going wrong. Using delay() in effect stops you from doing anything else.
