Responding to incoming midi?

[malkomalko]

I've setup an On MIDI execution script to be fired on some pads whenever any note on message is being sent for any range and any channel.

However I don't see anything coming back in my application. I've set the MIDI_ARGS to Monitor.value and nothing is being received. Am I thinking about this the right way or do I need to do something completely different?

I'm basically trying to interpret data being sent from a clip in ableton to 'light up' the correct pads so I can get feedback from playing parts.

Thanks!

Hi
It is often difficult to try to determine the problem from text descriptions - please include code or part of project . . .

From what you have written it sounds like you have done - MIDI_ARGS = Monitor.value - it should be the other Monitor.value set to MIDI_ARGS Monitor.value = MIDI_ARGS . . .

Using a Monitor called NoteIn, add a script called Midi_In or whatever you like . . .
Set Execution to On MIDI - 90-NoteOn - MIDI 0 - 0 to 127 (all notes) - 1 -16 (All channels)
NoteIn.value = MIDI_ARGS;

This will display the MIDI_ARGS array in the Monitor object - access via indexing > MIDI_ARGS[0] is NoteNumber ,MIDI_ARGS[1] is Velocity, MIDI_ARGS[2] is channel . . .

To indicate via a Pad called Pad1, add the following
if(MIDI_ARGS[0]){ // If any MIDI note
if(MIDI_ARGS[1] >= 0){ // If velocity > 0
Pad_1.x = 1; // Pad on
}
else Pad_1.x=0; // or else Pad off
}

Hope that helps

Thanks for the reply .

This is exactly what I was trying to do but nothing is being received by the lemur. Do I have to do anything special from my DAW to send midi information to the lemur?
When I say nothing is being received by the lemur, I mean that when I have that script and I do Monitor.value='hello', just so I can see that it's responding to the script, nothing is happening.

Hi
Anything special - well set up the Lemur Daemon, set MIDI channels & I/O in DAW etc . .

Please send some code or something more tangible . . .
Not sure what you mean about not receiving / responding? Putting Monitor.value='hello' should just show hello in the Monitor - no 'responding' needed . . .

The script I posted works in response to MIDI sent out to the Lemur from a Live MIDI track . . .

Cheers

I'm having a similar issue except with both sides, Traktor and Lemur. I've been trying all the code I can find but still nothing. Here's the problem.
When I start playing a song in Traktor from Lemur (this is working) I would like an object to show the song position. In Traktor I have setup a General Midi Out which is sending Seek Position on Channel 1 in cc 23. If I look at the output from Traktor using Midi Monitor it shows:

12:36:58.868 To Daemon Output 0 Control 1 Controller 23 31

The 31 at the end of the line slowly increases with a period of about 2 seconds so it doesn't fit the use (sub second) speed that I need for my function. So I am baffled by how to get this to work and any insight would be greatly appreciated.

TIA,

Hi
Not sure if you got this sorted but I think the issue is that Song Position Pointer is a 14 bit value
So you need to deal with that in your inwards processing-outwards the easiest way is to use pitchbend data.

Traktor doesn't send song position so I'm trying to fake song location using the midi clock
bah.....

Hi
It seems silly to only be able to use a 7 bit controller for SeekPosition
Surely the hardware controllers for Traktor use 14bits for that sort of thing . . .
Are you able to use PitchBend to get 14bit control?
Dont really do much in Traktor sorry . . .

I spoke to the Traktor folks directly and it doesn't send the time code. The hardware controllers do a bunch of clock manipulation which is kind of what I'm trying to do. There's a lot that's hidden and trying to get answers from the techies at NI is like pulling live shark teeth. I am getting closer. Just trying to idiot-proof the code so users can't make mistakes and throw the clock out of sync.

Thanks,
