Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
(I regret that I am not able to offer Live Phone Call service at this time; However, your request is still open to other Experts in this category, and one of them may pick up on it at any time.)
Generally, though Musicsoft can be used with CVP Clavinova instruments... but it may not be able to be adjusted as you say.
MIDI files can be downloaded, and played, from the Musicsoft service(s), and used on your Clavinova. But, they cannot necessarily be
A. played at the same time as an accompaniment
B. adjusted for chord changes... and possibly not adjusted for tempo or 'time'. MIDI files on computers are at a fixed and non-adjustable speed, short of editing the file (which cannot be done on your Clavinova, I feel fairly sure.)
I suspect that A. above is possible. But B..... I don't think so, at all. Not if it is a MIDI file played as accompaniment.
Let me know more about your requirements - I am competent in music notation and all music performance concepts, as well as the technicalities of Clavinova models, so I will be able to understand you fully without much explanation.
If this answers your question, please rate my answer. A five-star rating would be appreciated!
