No Serial for Kontrol S4?

Savard

Hi! After years of inactivity I want to sell my equipment. It's a Kontrol S4 (MK1) and a Kontrol F1. To avoid problems for the future buyer I have questions:

1. When I am logged into my account, only the F1 is shown as registered hardware. The S4 is not there. There also is no serial number anywhere on the device. Did the MK1s not have a serial number? Looks like the device works without registration.
2. In my account there is a "TRAKTOR PRO 2 for TRAKTOR KONTROL F1 HW" listed. Am I correct when I assume that this Traktor Pro 2 License works only with the F1, and I cannot sell them seperately (for example S4 plus Traktor)?
3. That Traktor Pro 2 version still qualifies for the TP3 upgrade at the reduced price (49€)?

Thanks! I just want to make sure I advertise everything correctly.

1) You probably did not register your S4. I think, HW code was printed on a card that came with it. Maybe NI could give you new one, or say what registration code was assigned to your S4 (if it has the production number).

It would be handy to have the registration number for future buyer, as it probably also gives him licence for Traktor.

2) Yes, bundled SW (TP2) should be sold together with HW (F1).

3) Yes, TP2 licence (bundled with F1) should be upgradeable to TP3. It may even happen, that new F1 owner will get TP3 and not TP2.
