I have been thinking about the practical details of scoring for orchestra.
While a composer might write on staff paper with fixed tempo there will also be directions such as accelerate, decelerate, play with feeling, etc.
In the computer this has to be dealt with either by playing the parts live and ignoring the tempo grid, or by mapping out a tempo grid so that one can enter the midi in the grid (or play it to tempo with the grid)
If played live, are there sequencers that can then map a tempo grid to the notes?
How do you deal with this?
Are there books or papers on the internet that I can get that deals with these sorts of practical issues?
