Title: Splitting on more Channels
Post by signs on Nov 8^th, 2010, 10:02am

Hello,

I've got a Vestax VCI-300 DJ Controler.
In the middle of it there are 2x 12 LED's for Showing the actual VU of the Music.
Now I want to use the Controller for other softwares, too.

Changing the Mapping of the LED's wasn't a problem. But now I've got the idea to use the 12LED's for showing the status (Midi-Feedback) of the fader next to them.
So I want to say: "If in-channel 3 is between 10 and 0 only the LED at the bottom (out-channel 25) should light up". "If channel 3 is between 10 and 20 there LED 1 and 2 (out-channel 25, 26) should light up" and so on.

All the LED's have an own Channel with Note On/Off function.

greets!

Is there any possibilitiy to map it like this?

MIDI only has 16 channels (numbered either 0-15 or 1-16), so if you're seeing a channel number outside this range, you'll need to explain why first.

Also, saying "If in-channel 3 is between 10 and 0" doesn't mean anything in terms of MIDI events. What event are you talking about? A Note On? And does the "between" refer to its Velocity? In that case, you don't want to include 0, as that means Note off.

So...

If you want to match incoming MIDI Note On events, based on the incoming channel and velocity, passing through the event and creating some new event (undefined), then yes, MIDI OX is designed to do exactly this... But it does depend on what that "new event" is...

Hallo,
thanks for the answer so far.

Ah ok. seems that this was my fault.
I alwasy say Channel for the Data 1 value. I don't exactly know how to name this.

well again. what I want to do.
I've got a Fader. near to this Fader, there is a line of 12 LED's.
These LED's can be controlled with Note ON/Off events. The Fader gives a ControlChange-Signal.
When I push the Fader to the top alway one more LED should light up. so maybe if the Fader has the value 100, 10 LED's should light up. When the Fader hast value 10 only one LED should light up. Do you know what I mean?

You can say: I want to have a lightFeedback for the Fader.

How can this be done? I tryed some houres with the mappings and sometimes got good results. But they had been really slow. It just worked when I moved the fader Slowly.

Greets from Germany!

Sounds pretty simple ... theoretically. You just have to find out what MIDI event is being sent by the faders and what MIDI event and values are being used to light the LEDs.

When you have this information it will be easy to create a map with MIDI-OX.
