Hi John,
Please have a look at our available Cubasis LE tutorial to see a short demonstration of the available routing options. If further channels can’t be selected as described by Jan, this might be related to a hardware limitation.
Unfortunately we’re not equipped with Behringer’s XENYX 1002 mixer device.
Therefore we suggest to get in contact with them directly, to check the available options.
Of course, we’re at hand to have them equipped with a Cubasis promo code for testing purposes, if required.
Hope that helps.
Best wishes,
Lars
