list, if it didn't set it self automatically, choose ERAE Touch.

Load your favorite VST, choose your layout, scale and start playing directly!

Cool feature to use for live performances: If you want to send MIDI Information to your ERAE Touch, you can select it as an Output channel from your track in Ableton, and have your ERAE Touch light up with the notes that you already played in a MIDI track.

You can also have multiple elements from your ERAE Touch linked to multiple instruments on the DAW.

In order to know what channel your element is in: tap on your element, and hold the bass clef button on the top of your Touch. On the top right corner, you can find the channel number of the element that you want to use as an output. After that, you can assign that channel number to any track output in the DAW that you are using.

Et voila! Now you can enjoy your ERAE dancing to the beat!
