Hi ! I’ve finally managed to control the mutes on my A&H SQ-5 mixer from Logic Pro automation. For example, a translator uses CC#41 with a value of 127 to send it as an NRPN (14-bit) message with a value of 1 to mute a channel. To unmute it, I created a second translator to send the value 0. Now, to control an Aux Send fader, I created a translator using CC#119, making sure to check ‘any value’ so that all the values ​​from my automation are sent to the SQ console. But I don’t understand why I can’t choose any value for Outgoing. If I leave the value at 0, as soon as I trigger my Logic automation, the relevant SQ fader returns to 0 (which already proves that the translator is correctly assigned), but why can’t I allow all values ​​from 0 to 127 to pass through? ![Capture d’écran 2025-12-22 à 16.13.00](https://forum.bome.com/uploads/default/original/2X/0/00ca29a362440cd460672fe5ffd423e86bd7b3c6.png) ![Capture d’écran 2025-12-22 à 16.13.19](https://forum.bome.com/uploads/default/original/2X/f/ff62ffc28d2b415c0eb849fdbb34653213aad21a.png) ---

Hi on incoming ,use any value set to qq. You are not setting a variable. On outgoing, instead of 0 make the value qq. Steve Caldwell Bome Customer Care * * * _Also available for paid consulting services: bome@sniz.biz_ ---

Thanks Steve, and Merry Christmas. I tried this, but the fader isn’t responding: ![Capture d’écran 2025-12-24 à 12.07.56](https://forum.bome.com/uploads/default/original/2X/a/a43b44b89c838954fa80879e23fcbd75f43ad5f3.png) ![Capture d’écran 2025-12-24 à 12.06.02](https://forum.bome.com/uploads/default/original/2X/a/ab105ccfa3647dbbab22369a1a42cd396bd2728c.png) ---

Hi, First of all, I believe you were using the wrong NRPN Number. I set it as IP1 to Aux1 because you didn’t say which Aux you wanted to send it to and which fader your were using. If I picked the wrong one, you can change it based on the SQ5 MIDI protocol document. After that I noticed you were not using aliases so I set them up as follows for my testing. You can change their assignments for your environment as needed. ![image](https://forum.bome.com/uploads/default/original/2X/c/cdb01bd22e48902cdbfd58ddb38d06b57d9e14eb.png) You can learn more about aliases from [this tutorial](https://youtu.be/CrE391VJL0s). Then I changed your MIDI router to use the new aliases. ![image](https://forum.bome.com/uploads/default/original/2X/b/be1fea4cfe33ba968e5f323053a9727ca9ae0623.png) I set up preset 0 to only accept incoming messages from your device and send only to your SQ5. The way you had it, it would accepte form any device and send to all devices which is not what you want. ![image](https://forum.bome.com/uploads/default/original/2X/e/ec4bb1a9881d6536f8a72796c89ea7a3c84f787c.png) For more information about device selection, see [this tutorial](https://youtu.be/KunN2A1rKMY). I addeded this formulate in 0.6 to convert from incoming 7 bit CC value to outgoing 14 bit NRPN value. ```auto // convert 7 bit to 14 bit tt=qq*16383 tt=tt/127 ``` The output value will be tt. I created a new presets (1) for reverse translation and set up the input from SQ5 and output to your remote fader. ![image](https://forum.bome.com/uploads/default/original/2X/2/2ad55826d8e1142d5a5a2d6a8e682147efde7829.png) The reverse translator has rules to convert back from 14 bit input value to 7 bit output value to CC. Again, the output value is in local variable “tt”. ```auto // convert 14 bit to 7 bit Log "Log input value =%qq%" tt=qq*127 tt=tt/16383 Log "Log output value =%tt%" ``` Hopefully this will get help you going further.

To answer your question, the destination auxiliary output is Aux 3, the relevant fader is ip15 when ‘Mix 3’ is selected on the right side of the mixer. That’s what I meant by writing ‘ip15 aux3 send’. If I chose ‘MSB=65, LSB=110’, that’s what the capture showed when I moved the ip15 aux3 send fader on the SQ-5, and… before you told me to select the variable ‘qq’, I typed a random value in the Outgoing Value field (for example, 0, 65, or 127), then I would play Logic CC#119 automation , and then the SQ fader would reset to the entered value. So I deduced that the assignment of my CC to NRPN was correct, except that I couldn’t allow all values ​​from 0 to 127 to pass through. I thought it wouldn’t take much to fix.. ![Capture d’écran 2025-12-26 à 11.20.29](https://forum.bome.com/uploads/default/original/2X/4/4b2a661112fb62f9b9f9005c678f50f35518842e.png) … but I didn’t expect to have to create aliases, delve back into the manuals, convert 7-bit to 14-bit, write rules, change my MIDI routing.. In truth, I only use Logic and no other controller to automate the console; the reverse conversion is only useful for identifying NRPN messages from the console (in ‘capture’). ---

So if you change the correct NRPN MSB and LSB does it work now? You can always go away from aliases if you would like. They are just meant to make it more portable. I haven’t checked if your NRPN number is correct but I’m assuming you are probably looking at the SQ5 manual. Yes you need to convert 7 bit to 14 bit which is required by the SQ5 so that you get the full range of the fader.
