Scripted musical notation available

[Kurt Kaufman]

 >>>I was wondering if you could answer for me if =
it is possible to map a midi note to another midi note. For example, 
can =
a scale be represented as midi numbers, like 64 66 68 69 etc, 
signifying =
C D E F, and then to map that to 70 72 73 as the output, for example? 
So =
an input note (the key pressed on the piano keyboard for example) gets =
outputted as a different note. <<<

This would not be difficult, as a transposition mechanism would simply 
add to or subtract from a given note number.  This would be done "at 
the top", i.e. immediately upon input, or, if a series of note numbers 
is saved in a container such as a field or variable, before the series 
is translated into MIDI data.

 >>>I can see that perhaps code can be =
written into a standalone midi file processor and, when a midi file is =
imported into it, can change the output of the midi file, and these =
changes can be saved to another midi file. <<<


Here's the difficult part though: it's much more straightforward to 
create a MIDI file from piano-style keyboard entry or HyperCard-style 
representations than it is to import an external MIDI file (as I've 
mentioned before, many MIDI files contain proprietary and/or 
hardware-specific data which would have to be filtered out).  However, 
in the long run, MIDI file import would probably be the way to go, as 
opposed to a HyperCard-style shorthand, since the core of the "Standard 
MIDI File" (SMF) is a generally accepted way to share MIDI data.
If the goal is to enable transfer of data only between applications 
that "understand" the HyperCard-style shorthand, then the job is likely 
considerably easier.

In any case, since you mentioned that you are new to programming, I 
have to say that I don't think that working with MIDI is a reasonable 
first programming project (unless you already understand how MIDI 
works). Once you get familiar with Revolution, take a look at the MIDI 
Builder stack (included with Revolution 2), and you might get some 
ideas as to how to implement the first part of your question, above.

HTH,
