You can use multiple MIDI controllers to control one MIDI hardware/software instrument. Provided the instrument has multiple inputs, or you have a way to merge MIDI signals.
The MIDI expander does not merge MIDI information on it's own, so if you are hardware only, you'd need a separate MIDI merger.
If you're using a computer, you can send MIDI information from your computer (or other connected MIDI controllers) out of the expander, as well as using the 12 step to send MIDI out of the expander.
