The current way you can hear the Chord Track is both limited and problematic. Right now you can either set it to play on any monitored track(s), or direct its output to a specific track. If you set it to a specific track you are limited to one and only one track. The only way to hear multiple instruments playing the Chord Track is to set it to play on monitored tracks. However this causes a problem when you open a midi part to edit because monitoring gets turned on for it and you start hearing the Chord Track playing on an instrument you likely don’t want it to. It’s also a problem if you monitor a track so you can hear what what you are playing on a keyboard - you get the Chord Track too, even if you don’t want it.
This could all be easily avoided if instead of telling the Chord Track where to send its data (like now), it just appeared as another midi input for tracks to select from. That way you could have as many tracks as you like play the Chord Track and you could turn on track monitoring without it playing stuff you don’t want to hear. Also it seems this would be more aligned with how Cubase deals with midi for everything else.
