Copy/xchange/mix Clarification

The manual sez:

I know how to select an instrument and a sample of that instrument in the instrument selector, but don’t understand how to specify one as the source and the other as the destination.

What it appears to be doing is replacing, mixing or exchanging the currently selected sample of the currently selected instrument with the sample in slot 00 of the last instrument selected before selecting the current instrument. Is this on the right track? Thanks…

On the side of the instrument name there is the instument numbers, you can select which instrument nr you want to be destination, by clicking on the instrument nr. And by clicking on the instrument name, you select the source.

The same goes for the sample nr in the instrument.

I might remember wrong so you have to experiment to see which selects the source and which is the destiantion.
