Wav 2 Midi

Hi Everyone,

I've just been working a bit more on the Wav 2 Midi section of
FTS, and it is slowly coming into focus.

Here is a recording of a seed played on recorder, then
the midi version as found in FTS, then a fractal tune
using it.

FTS has an option to quantise to the main window arpeggio
when you find the seed. However I didn't use it here, but
just used the pitches exactly as FTS found them in the
recording, in the order played. So it is a non ascending
scale. Since the first and last notes are 186 cents apart,
it means the scale repeats at an interval of 186 cents
for the non octave repeat.

Scroll to the bottom of the page to find it.

I haven't uploaded it yet - a bit to do. This was done
using the wave counting method, with a new idea - the tricky
thing about the wave counting is to decide which of the
zero crossings are for the beginning of the wave form
and which are just secondary wavelets in the middle of
it. So the new idea was to search for waves similar in
shape - if you look at a recording ,often each wave
is very similar in shape to the next, even though
the shape can be quite complex - and the shape changes
slowly, but each individual wave is very like the very
next one.

Anyway, it works well enough to make quite a difference
though certainly more can be done on it.

The FFT approach has an option to look for harmonic series
partials, which works well with e.g. string timbres.
However I have a little work to do on that too.

This is the last main section that I needed to complete
for the release, after which there are few loose ends
apart from need for a bit more in the help, which I'll
do after the release,

Cheers,

Robert
