With Tonaly Pro you can open the MIDI Output to send MIDI signals to other apps. In this way, you can use the sounds of your DAW and record MIDI. By using [**shortcuts**](/general/keyboard-shortcuts.md#general-hotkeys) 1-7 you can use Tonaly as an instrument.

👉 To do so, navigate to "MIDI" in the menu bar and click on "Open MIDI setup..." or use the key command **⌥ ⌘ ⇧ ,**

#### About Ableton Live 

*Problem: MIDI-Out does not work with Ableton Live*

*Quick fix: Restart your Mac*

*More about this:* At the moment there might occur an issue with Ableton Live. MIDI signals are received by Ableton but do not reach the channel. The MIDI indicator receives signals:

But the channel is not. 

I'm investigating this – at the moment I'm not sure if there is an issue with Ableton or if it is on my side. Sorry for the inconvenience – I hope to fix it soon!
