Its a common misunderstanding that you cannot copy a Pattern directly on the Arturia Spark hardware controller. This used to be the case before v.1.1.3, but since then you can use the following (super intuitive) work flow to copy a pattern:

1. Hold down [SELECT] and press [ERASE]
2. The Pattern select wheel will light up
3. Press the (Bank ->) Pattern button you wish to copy from
4. Press the (Bank ->) Pattern button you wish to copy to
5. The Controller LCD will say ‘Copying Pattern X to X’
6. Done

You can also copy entire Banks using the same pattern, just skip pressing the Pattern button.

This has been tested on v.1.1.4 as well.
