Maybe this already exists in the form of extract MIDI from audio(?)
But I’d want it more just for on screen reading and keeping track. I’d love to see an option where the score could be activated over the audio track region so you can read a bass part as you’re playing along, seeing the waveform cues and region/arrangement.
Could also send midi data in realtime to an instrument that emulates the one being recorded, so the musician can hear what they need to be doing in comparison to what they have played/are playing. Or for an engineer to understand what needs to be recorded if they are working for a composer who is not in the studio.
You could even have a feature where Cubase shows the comparison/errors between the defined score and what has been played.
Also then you could have a compositional overview of all your audio tracks to see what exactly is going on musically and even show what chords are being formed over 16 tracks or however many.
