Doesn't find device (KK S88 MK2)

[inspiredearth]

Hi there ...
First off, thanks very much for your work on this. It's really fantastic to see. I came across this via your thread on the old NI forums.

I have installed this on a MacBook Air M1. I have a NI KK S88 MK2 keyboard installed and working.

When I run qKontrol it tells me no device is found ("No Komplete Kontrol MK2 keyboard could be found. Please check if the device is turned on and connected to the PC! The program will be closed now").

Do you have any suggestions? Is it that this doesn't work on M1 / Silicon devices? Or anything else you can suggest?

Thanks so much...
Jonathan

Hello,

another possible reason may be a wrong / changed USB ID. When the program is being opened, it scans the USB bus for devices with the vendor ID 0x17cc and the device IDs 0x1610 (49 Keys), 0x1620 (61 Keys) and 0x1630 (88 Keys). Please find out if the IDs really match! To find it out, please run "About Your Mac" in the apple many, click the details button and there check the details of your USB device. If it is different, I have to add another ID in the code.

If the hardcoded ID (0x1630) is right, the M1 processor may be the reason. In this case, someone should try to recompile the program as an M1 binary and try out if the problem is solved if the program is run as a native M1 application. Possibly, the used library (libHid) cannot scan for USB devices through the CPU emulator. But I don't know because I am still on Intel and so I actually cannot find out this by myself.

At last, the problem my be that the application which was compiled on El Capital isn't perfectly upward compatible to the most recent version of macOS. In this case, re-compiling should also solve this.

Hi there ...
Thanks for the consideration on this.

Here's the data coming through on the USB:

KOMPLETE KONTROL S88 MK2:

  Product ID:	0x1630
  Vendor ID:	0x17cc
  Version:	0.59
...

So that all looks fine.

I am happy to compile on my M1 computer. I have Xcode installed. Would just need some instructions on how to go about it. Is that something you can point me in the right direction for?

Cheers ... Jonathan

Just go to the main page of the Github project and scroll down there to the build instructions. You need to install the QT framework and two small libs using brew.

To download QT, go there: https://www.qt.io/offline-installers and select QT 5.12, because the existing binaries are built with this version and I never tested if it works with newer versions too.

Regarding the two other libraries which need to be downloaded using brew, you will probably get never versions. Therefore it may be possible that you need to modify the path to the header files in the source code.

It looks like the libhidapi package is not longer available on Homebrew.
Any thoughts on that?

jonathan@Jonathan-MBA /Users/jonathan $ brew install libhidapi

Try 'brew install hidapi'. Seems to be renamed.
