#TRAKTOR S4 MK1 OFFER UP UPDATE#

〰️ Its not sure how many other USB controllers have this exact problem, based on the input from above, the S2 Mk1 has already fixed this by splitting the interfaces for the USB audio and the USB HID button/slider/led messages.

This requires some more work as currently Ctlra doesn't read linux-input-events, but this could be added.

〰️ Check if using linux input events is feasible, to leave the device under kernel control, and to provide Ctlra applications with a consistent event model by translating them.

❗ Audio card access is removed when we read the USB HID endpoint directly, as the kernel cannot access the device at the same time as Ctlra (when they both use the same USB interface).

✔️ Decoded data into the buttons/sliders events.

✔️ Successfully retrieved data from the S4 device, (requires using an 'alt setting' USB mode to get the data to be reported).

Hey Folks, updated code pushed to this branch long story short - success and rework required. $ sudo usbview # Then select the 'S4 Mk1' device on the left pane, shows this on right pane I guess it'll be similar to the other Mk2 devices (except possibly for the encoding part.) so there's some learning to do there. Regarding Ctlra support for these devices, it will take a bit of time to finish the input side of the S4, and I haven't started the output LED driving part yet. If anything, hat tip to NI for moving to USB HID, and for continually improving and innovating on the HW/SW combos they provide - nice work.

So the MK1 with Traktor 2 suits these purposes just fine. My set up is for home only: to test new tracks, practice, etc. Having worked with the Mk3 and Mk2 devices, the Mk1 protocol isn't quite as optimized for real-time and live usage - but its by no means an 'amateur' job either. Hi all, i am looking for some advice, I can get a s4 mk1 for traktor with software included for 250 includes flightcase. The 'NHL' although not a standard protocol like USB HID is, is not insane either - just just a different method of encoding bits/bytes using USB Bulk transfers.

Current status is that we can read bytes from the device, and they seems pretty 'reasonable' to decode and identify each slider.

Update I've gotten access to an S4 Mk1, which has allowed me to prototype some of the USB connectivity and figure out a few issues.
