Hi all,
Here is the finished piece I created using FMST.

If anyone is interested in how I did it: Here comes the science bit,
so concentrate ;-)

First of all, I created a short midi file by hand in Cakewalk. This
seed file consisted of 5 chords. This file was then loaded into FMST
(running in Steem). The seed file was subjected to a series of
rotations in FMST, the distance between each rotation was determined
according to the properties of the notes of each chord & each rotation
was started from the previous resulting rotation. Each rotation was
saved as a separate midi file. This process was then repeated, but
this time each rotation was always started from the seed file, but
using the same degrees of rotation as the first pass. In both sets of
rotations, there were similar small variations for each rotation in
terms of axis - once again derived from properties of the chords in
the seed file. I now had 43 midi files from the 2 series of rotations.
These files were glued together in Cakewalk. The starting (pasting)
point was determined by the second set of files that were started
always from the seed file & were more gentle in their transformation.
The 2 parts diverge slowly at first, but soon become very different
with only an occasional resemblance. By the time the second part has
gone 360 degrees & returned to the original chords, the first part has
finished somewhere else entirely. Although the pasting points in
Cakewalk were determined as outlined above, this does not mean that
each pair of rotations run simultaneously: The first set of rotations
start to gain silences at their beginnings & also noticeable
variations in length compared to the second set. Consequently, the
first set of rotations, although pasted in place at the same point as
the corresponding rotation from the second set, overrun & overlap as
the piece progresses - increasingly a file was pasted at a point
before the previous one had finished. Only the rotation facility in
FMST was used for this piece.

The end result of all this is a piece in a striking & modern idiom. I
intend to create a more tonal piece using FMST as my next task.

Gavin.
