Hello Sebastian
Obviously you are a musician or a singer.
I know that musicians are "heikle Kunden" when it comes to the interpretation of the Play-Along.
Why this introduction?
3 Minutes of Chamber Music (Chamber-Ensemble) means around 3 days of work.
Whishes like:
- Bei Takt 15-17 ein bisschen langsamer
- Takt 25 - 27 ein bisschen mehr piano
- Takt 39 - 45 ein warmes legato
will need another day of work...
Then you need to record and mix the voice... another 5 - 9 h
I don't want to disapoint you but I hope to show you "the sample side" of your wish.
So it could be that nobody "bite in the casted line".
4 -5 days of work (40h - 45h) for one piece... No money
Let's hope for you!
