Receiving data from ableton? in teensy 2.0

[noiseworker]

Hi!

I want to build a MIDI controller for Ableton live , then , I need to recieve data from Ableton to switch on or of the button's led .

How can I receive this data info from Ableton ?

Thanks

For the LED: Pretty sure Ableton can send a MIDI Note On back to the Teensy which you could use to turn on or off an LED (using the note velocity 0 for OFF, 1-127 for ON). Heck you could painlessly give the LED 127 levels of brightness if it happened to be on a PWM pin.

FWIW, The Teensy-using MIDI controller Instructable by FuzzyWobble is slightly dated (1.5 years old) but it was way ahead of it's time, making it very timely: http://www.instructables.com/id/A-Framework-For-Making-Affordable-Stylish-Modula/

True, he is not way into the LEDs, but it is a big and helpful jump past the demo code that comes with the Teensy.

Is this a controller for notes, or a controller for start/play/record etc?

I agree, DrJohn really answered this well.

You might also try the example code in File > Examples > Teensy > USB_MIDI > PrintIncoming. Just run the example, open the Arduino Serial Monitor to see the data, and try to send MIDI messages from Ableton. When you get stuff printing in the serial monitor, then edit the code to use those numbers to control your LEDs.

Note On isn't really what is needed here, if the intent is to do transport control (which, from this other thread it seems to be; note the mention of "rec" and "stop"). I think MIDI Machine Control (MMC) would be the appropriate solution. But I'm not sure exactly what the problem is, hence my earlier question.

Hey guys,

How did you go with this? Ill be starting up a similar project soon so would be interested to know.

perhaps this could be of some use? I recently used this little tutorial to sync my teensy midi controller with my ableton bpm clock

Thanks for this, I was looking all over for code examples, and it was right there all along.
