Before I get into the problem, I want to mention that I've had the Impulse 500 for 2 years, using it every weekend at some event or party. It was working perfectly with a laptop:
Macbook Air (mid 2012)
Core i5
4GB DDR
128GB SSD
MacOS Catalina
DJay ProAI
But because this laptop is old, I couldn't use the stems. And I really wanted to use it to improve my performances. But other than that, I went everywhere and everything worked perfectly.
A month ago, I changed my laptop to the following:
Macbook Air (mid 2020)
M1
8GB DDR
256GB SSD
MacOS Sequoia 15.1.1
DJay ProAI
Now my problem started. The jogwheel touch no longer works perfectly like vinyl, it keeps failing a lot, which prevents me from scratching my performances.
I updated the controller firmware to the latest version (v6.51) and the problem persists.
I saw in other posts that it was possible to test the controller on the website midicontroler.com. I did this and it gave all the results they said it should, but it still fails a lot.
Help me Hercules!
Hello Brunolima,
Welcome to the user forum (this is not Hercules support, Hercules support is on https://support.hercules.com/en/contact-en/ ).
Touch detection on DJ controller jog wheels is a capacitive detection, so it uses the electric grounding.
If there is not enough grounding, the touch detection is probably not good.
As the DJ controller is powered by the USB bus power, the grounding is the grounding of the USB bus.
If there is not enough grounding, the components to check are:
- The USB-C to USB type A adapter: make sure you use a quality adapter, as for example Apple USB-C to USB adapter. Avoid very cheap USB C adapters.: If if the USB-C to USB adapter is not properly grounded, capacitive detection cannot work well on a USB device connected to this USB adapter.
- The power supply of your laptop: if you have a good USB-C adapter, but use your laptop on its battery, without connecting the power supply, the power grounding depends on the chassis of your MacBook, which may be too small. Make sure you use your laptop connected to its power supply connected to a wall outlet.
In case the power supply of your MacBook is not well grounded (if you use an Apple original power adapter, it should be well grounded, but if you use a cheaper alternative solution, its grounding may be not so good), an affordable solution is to connect a USB hub powered by a power adapter between the laptop and the DJ controller: the DJ controller touch detection will then use the grounding of the power supply of the USB hub.
Hello UXteam, thank you for your feedback.
I tested it with this adapter that you told me I already had because I have another MacBook that I use in my office, but the problem persisted.
So I bought a new cable from UDG that connects directly from the controller to the laptop. And that didn't solve the problem either.
This weekend I'm going to try this Apple Adapter that receives power, that's my hope!
I'll be back with the results on Monday.
BR,
