Other than using cut and paste in the piano roll, is there a simple way to add a clip to the end of another clip ?
One way is to add enough empty bars at the end of the clip you want to add to in the pattern overview, then copy the clip you want to append to the clipboard. Then highlight the first empty bar of the first clip and select past.
I probably explained that badly, but too tired to try to do better right now. Hopefully it makes sense. At any rate, all operations take place at the clip overview level, no opening of the piano roll is needed.
Sorry for the vague post. Hopefully someone will come by and do a better job.
Thanks @number37, that is exactly what I was looking for. And explained it well.
