Logic Pro X failure with Midi Controller Samson Graphite MD13

On my Logic Pro X > Preferences > Control Surfaces , I cannot see the Midi Controller Option either for the Midi controller I'm using.. It seems to be read automatically by Apple > Logic Pro X .. Samson Graphite MD13.

The same is true for : New Track > External Midi > NO Option for a midi in there.

Another way to go : New Track > Software Instrument > Instrument Bar > NO Midi Option in there.

NOT SURE IS THERE IS SOMETHING WITH LOGIC OR WITH THE MIDI EXTERNAL SOURCE.

IT SEEMS TO BE BOTH,

It is set on Control Surfaces > Set Up > Mackie Control with Samson Graphite MD 13

It is set on Controller Assignments.

It is set on Applications > Utilities > Audio Midi Set Up ( but it seems doesn't need a driver for that )

It is receiving signal.

I have downloaded the program from the manufacturer to set up ,

But I can hear no sound.

I've called Apple Autorized Technician and he gave me few tips to get my computer rolling better.

But also told me to get in touch with Apple Pro to get a tip,

Try some other computer,

Otherwise is the product.

But the program is not reading really well, missing things or steps.

Is this Sierra or something ?

Thanks
