These nuances are what I am trying to reproduce in HARMONY by the use of Note styles.

I have written for my own use a small program which extracts from a MIDI all of the controls applied to a specific note into a file, which I can use to create suitable note styles. (It is a bit like what you can do with text using a word processor.)

Sometimes a single note will be subject to 10s or even 100s of events.
It is therefore easier to find an effect you like and copy it (like sampling, in a way)

I am currently planning a style editor as an add-on to HARMONY
A few style files made by hand have been distributed with the latest version of HARMONY, just as examples of what is possible.
(They are CSV format text files which can be edited by hand)

For example, to simulate a trill, the events in the style file will turn the note on and off repeatedly, with change of pitch if wanted.
(Just changing the volume and pitch does not give the right effect)

Some really wierd effects can be obtained by simple actions, such as panning each note left and right.
