Hi, Bongout:

Do you mean two different midi (.mid) files or input from two different midi keyboards?

The first is as simple as cutting and pasting.

The second requires, at least, an interface with two Midi In jacks and judicious setup. Set both keyboards to send on the same midi channel and direct the track you wish to record in to that channel. Provided both keyboards are on the same midi port and channel, then Composer should see both data streams as one.

Just don't play the same notes at the same time, or you'll get stuck notes.

OR:

Just record the two keyboards separately and combine them as needed.

Good luck.

David
