HELP im losing my mind over arturia keylab mk3 61

hey, i bought arturia keylab mk3 61 last week. my keyboard works perfect with analog lab, no problems.

so i wanna do sound design in logic pro with faders and knobs and i almost did it. (with stock sounds and stock plugins)

but the problem is when i (even slightly) touch the 4th knob, it mutes the whole sound. when i touch it back, unmutes again. basically i constantly have to keep my hand on knob 4 to hear anything. also if i never touch the 4th, all of the other faders and knobs working perfectly.

this is my first midi keyboard, sorry if i sound ignorant but im gonna lose my mind over it. someone PLEASE help agh

(pc: macbook air m2 (2022) (sequoia))

(also i did all the logic updates, installed logic script and got firmware uptades of keyboard etcā€¦)

I use Logic but not a Mk3 KeyLab. Sounds like it could be a mapping problem. It could also be that Arturia has made it clear that their software (which I guess includes their hardware drivers) is not yet Sequioa compliant and advised Mac owners not to upgrade until it is.

Compatibility - macOS Sequoia ā€“ Arturia FAQ

This may or may not be part of the reason. When you rely on third-party (non-Apple) apps itā€™s always wise to check if the developer has 'okā€™d the OS upgrade before succumbing to Appleā€™s nag-screens. I have no plans to upgrade to Sequoia until Arturia tells me to.

Maybe other Mk3 owners using Logic can chime-in with their experiences.

(EDIT: I guess you probably upgraded the OS before buying the keyboard which is unfortunate.)

Hey there

I have KL3 61 and Logic Pro - and Iā€™ve had that happen (Iā€™m on Sonoma btw, I donā€™t think Sequoia is the issue)ā€¦

Just checking the output in midi monitor and touching knob 4 is sending 'control 1 - with a value of 127 - then when you let go it is sending ā€˜control 1 = 0ā€™

Hereā€™s the output in midi monitor (touch, let go, of knob 4)

04:41:25.238 From KeyLab 61 mk3 DAW Control 1 Expression (coarse) 127
04:41:25.882 From KeyLab 61 mk3 DAW Control 1 Expression (coarse) 0

I canā€™t get it to do it right now - but Iā€™ve seen it, when I was first messing

What plugin are you controlling at the time - Analog Lab 5? And what mode are you in on the KL3 - Arturia?

If you are in DAW mode (either plugin or mixer, there are 2 sub-modes) try going into Arturia mode for your sound design - and then switch to DAW.

Iā€™ll keep a check on my system and report back if I get it to do it again and have more insight.

BTW - MIDI Monitor is https://www.snoize.com/MIDIMonitor/ ā† very useful and free.

Hello,
I was going to report it too as Iā€™m facing this issue exactly for a couple of weeks.
KeyLab 61 mk3
Logic Pro 11.1
MacOs Sequoia 15.2
MacMini M4

To me this happens on non Arturia plugins only (eg Alchemy, Pianoā€¦). As soon as the knob is touched, the sound gets muted and remains so. Strangely, touching the knob resumes the audio, but only when a finger touches it ; when untouched, the instrument keeps mutedā€¦
There is no systematic recovery strategy. Sometime turning off then on the plugin is enough, sometimes itā€™s not. Alchemy recovers this way, Piano randomlyā€¦
This happens in DAW mode, not in Arturia mode (seems the midi is not directed to the DAW).

I havenā€™t dived in the Midi details here, no expertise for that. But itā€™s obviously a bug either in the integration script or in our kbd firmware (I doubt)

Hi all.

I donā€™t use Ableton Live.

Be sure your controller is set up correct.

I canā€™t tell, if this is about the OS.

If you have issues, then i suggest you contact Arturia support through your account.

Hello @thecastrato ,

Can you tell me which firmware version is embeded in your keylab mk3 please ?

it remind me an issue we had in the FW 1.0.4, but this should be solved in firmware 1.1.1 with Logic Pro X.

keep me posted, cheers

Bastien

in my case , FW is 1.1.1ā€¦

Iā€™m experiencing a similar issue. The knobs and fadersā€™ progress displays blink in and out, then after several seconds of making changes, the audio cuts out completely and I have to reset the controller. Iā€™m using the following:
KeyLab 61 mk3, Firmware 1.1.1, set to Logic as DAW
Logic Pro 11.1
MacOs Sequoia 15.2
MacBook Air M3
Iā€™m not using a USB hub. Perhaps itā€™s down to waiting for Sequoia certification, but either way looking forward to a resolution.

I went back to MacOS Sonoma, same issue. I have a case opened. If we resolve it Iā€™ll share here.
