Can a license key be used with a product other than the one it came with?
Yes, it can.
For example, if you have activated a rekordbox dj license key that came with DDJ-400, PERFORMANCE mode can be used when connected to CDJ-2000NXS2 as well.
*Even if a product comes with a license key, it cannot be used if the key is not activated.
*When using DDJ-200 in PERFORMANCE mode together with another product, a rekordbox dj license key is required.
