Hi!
Anyone using retrokit rk006 with intech studio grid controllers?
I run into the problem that my intech studio grid controllers blink wildly in all colors when I connect them to the retrokit rk006 midi hub.
Before I used the grid editor and updated the firmware of the grid devices. when I power them from the computer, all works fine. Any ideas? Thnx!
How do you connect Grid to the rk006? Afaik the 006 only has TRS inputs and now way to host a controller on its own.
With the included OTG Cable you can have it act like a 5V powered USB
Standalone host.
I think the problem lies in the USB-C cable I used. I think it only can transfer power, not data. I need to test this.

Oh, I didn’t know about that, that’s a very cool feature!
Please test it with our Intech branded cables if you have them, they do transmit both power and data.
I did not receive any intech branded cables with my grid devices. do they normally come with cables?
If you want, I can test with your cables, but you would need to send me some. 
I would need USB-A to USB-C to test.
They are nothing special, just 2.0 USB C-A cables. It’s not automatically included to Grid modules since we assume you already have some lying around at home, like a phone charger cable.
I will tell, just ordered some “normal” Anker ones.

Doesn’t work. 
The grid devices still blink widldy and colorful. Maybe I have to return them. Sad.
How do you mean it blinks? Which color?
We also just issued a new FW update for the Knot, might be worth updating it as checking if it works better afterwards.
I don’t own the knot, so I unfortunately can’t test.
It blinks in all colors.
Oh sorry, that’s my bad. Your case doesn’t have a Knot at all.
If the module is blinking in all colors, that is usually a power issue!
This means that the rk006 doesn’t provide ample power. If you have the specification for the OTG mode, you should be able to find the provided power there.
For Grid, each module could pull up to 250mAs of current at the USB port. If the rk006 can’t provide that, then it will result in blinking.
That was the missing hint. Thank you!
