Hey, my MIDImix has problems with turn the lights on if they triggert or pushed or whatelse. I only tested the lights on the MIDI monitor "MIDIox" there they go on without problems, but can`t go off. They are only one after push the button and stay there. If I want to take the lights off need to disconnect from my usb hub and connect again.   I use the MT pro for switching channels on the MIDImix. If I push the button CC:1 no lights go on. I have tried to do this with "note on" and "note off" technique which is here on the forum as an example. But my MIDImix don`t show reaction on it. So. I want to make: Push the button CC:1 the light go on and stay there, as long I am on channel 1 (in this example) By push the button CC:2 , which is channel 2 , the light from CC:1 should go off and the light from the button CC:2 should be on and stay there. Did we have a possiblity to make this realize?   Thank you kind regards Mike **Attachments:** [![](upload://zS8b6doy1jSsNsoDGtvHoqcbsyf.jpeg)](https://www.bome.com/wp-content/uploads/cma_attachments/1571165931304_MIDImix-preset.jpg) ---

Hi, could you turn on logging in MT pro select MIDI in and push and release each of the buttons you want to control channels. Then show me the log? Also, if you create a loop back to your controller, with MT pro using MIDI thru routing, does the LED go on when pushed and off when released?   You should be able to use the attached project file for this. Just assign both input and output to your MIDI Mix.

Hey Steve,   also the lights didn`t react on it. Did it with your instructions nothing happens. Only they react on the midi monitor from the “MIDIox” software. Can`t understand why.   kind regards Mike **Attachments:** [![](upload://dDe7Kwru4UZE3TQXn6qnJtBKmhi.jpeg)](https://www.bome.com/wp-content/uploads/cma_attachments/1571168399015_MIDI-test.jpg) [![](upload://sfETDxZoHCAt1YC0oUwsm2YPc0d.jpeg)](https://www.bome.com/wp-content/uploads/cma_attachments/1571168408938_MIDI-thru.jpg) ---

Here are the MIDIox sends. And the lights are constantly on after push the buttons. **Attachments:** [![](upload://2No113ZK5v30VSHMi7PH5lu5eOJ.jpeg)](https://www.bome.com/wp-content/uploads/cma_attachments/1571169954265_Lights-on.jpg) ---

Different incoming messages for MIDI OX as for MT Pro. What happens with MIDI OX is you send CC instead of note to MIDI OX? ---

Okey, you got me again. On the MT pro I had my MIDImix buttons with CC not with NOTE. MIDIox has got the buttons in NOTE not in CC. Can´t understand why this is there reseted, but equal. Now, I tested the same thing on MT pro, now the lights go, after doing MIDI thru (MIDImix to MIDImix) and stay on after disconnect from usb hub. ---

So with MT Pro the lights come on with CC push and stay on with release of CC? ---

No. The Midimix is reseted . So all buttons are notes and aren’t CCs ---

OK, then you will need to make it notes also on the Channel switcher project I sent you. You. ---

Normally I should do the 16 buttons into Notes. It would be great, if you could help me with the lights on. I can’t understand why they don’t go on with the midi message note on/off ---

Yes! It runs. If I route MIDImix to MIDImix, I can turn the lights on by push the button. The light is only on, if I push the button and go off if I go from the button. But if I route MIDImix to Virtual Midi Translator, nothing happens…. ---

Right it appears the the LED wants to see LED off as 90 xx 00 instead of 80 xx 00 which is what the MIDI Mix sends. So you will have to modify the output going back to the MIDI Mix and also use Bome to toggle the LED’s instead of making them momentary? I’ll add an example for the first two Channels that include the LED toggling.

This should handle LEDs for MIDI Channels 1 and 2 for your project. MIDI Mix requires 90 xx 00 for note off but sends 80 xx 00. We use a bit map variable zy to determine which LED’s are on or off and iterate through them with a timer every timer a channel is switched. The value of zy is set by the first translator of each channel in rules when the preset is activated. The preset LED Update handles all of the LED display logic . A channel switch is signaled by any note on on MIDI channel 1. Again, I only put in logic for the first two channels and first column of controls.   Steve Caldwell Bome Q and A Moderator and Independent Bome Consultant/Specialist [bome@sniz.biz](mailto:bome@sniz.biz) **Attachments:** [**1571260305816\_MIDI-Mix-Multi-Channel-Takeup-Example-2019-10-16b.bmtp**](https://www.bome.com/wp-content/uploads/cma_attachments/1571260305816_MIDI-Mix-Multi-Channel-Takeup-Example-2019-10-16b.bmtp) ---

Hey, this didn`t runs. I have try some things. If I route MIDImix to MIDImix and take off the preset “Channel Switch” the lights go on. And stay on. But nothing happens with other changes. Maybe, the lights would be they own light bits? ---

Could you show me how you have your ports set up. Perhaps you have the Alias for output to MIDI Mix set wrong. Go to the MIDI menu and make sure you have your aliases assigned correctly. ---
