Slave Ableton to an Pioneer DJM 900. Trying to send one midi clock (sysex?) message with a button using a m4l device.

Hi Guys and Girls,

The DJM 900 has a midi port which spits out midi clock. Sadly Ablton can't sync to this because the DJM does not send a "play or continue" command which ableton needs to start transport. I've managed to merge the midi clock message into the midi clock stream using a cool app called midi pipe. http://www.subtlesoft.square7.net/MidiPipe.html

When ableton receives the midi clock start or continue message transport starts. Succes! :)

I would like to simplify this proces by adding a m4l object to my session which has the following functionality:

A button that generates the midi clock start message. It would be excellent if i could choose the midi port the message is sent to. I've started fiddling around but as a m4l noob I did not succeed.

Here you can find the necessary message that needs to be sent: https://en.wikipedia.org/wiki/MIDI_beat_clock
I think using the "continue" message would be the most appropriate as ableton joins the midi beat clock stream somewhere in the middle.

Hope you can help!
