Hi Clemens,

Yes, I've focussed mainly on getting it coded first, but I know that many options
need more in the way of help and tutorials. I understand the frustration of knowing
that FTS can probably do what you want if you knew how!

It can already find pitches in a recording and you can try this out:
View | Analyes recording or Midi Voice | Open Audio File
Then Find Seed (that is because I did it originally for fractal tune
generation) then Find Notes.

Click on Show Recording, or Recording (temp...)
to see if it has found all the notes, or found more or less than it should.
You can use the Find & -> Seed option to get it to play back the frequencies it
found.

If you are lucky it may just find them straight away, and you will see
a list of the frequencies it found.

If you go to Options for ->Seed and you will see a small list of preset frequency
detection settings at the bottom and you can try them all and perhaps try
tweaking some of them - be sure to ask if you want help there.

If the results there look workable then you will see if it is worth persisting
with it in its present form.

Yes, I know what you mean about the intuitive approach to scale making.
I play tunes and improvise microtonal scales on my recorder and have no idea what they
are either. Just that they sound good. Some time I'll have a go at analysing
them too. I don't listen very analytically myself either when improvising,
much more an emotional intuitive response to the music. I'd need to use
FTS myself to find out what the frequencies are that I play. But
some here are much more analyticial in their listening and can readily
identify intervals that they hear and play.

Do upload some of your recordings - I'm interested to hear them.

Yes, FTS can retune any note to any other note. The things that affect that
are:

The pitch window just shifts it up and down.
The Arpeggio drop list selects notes from a scale. So if you want particular
twelve tone notes to be played from say the white keys, choose a twelve
tone scale to play in, then just put the numbers of the notes to play
as scale degrees (for twelve tone scales, numbers of semitones above the 1/1)
in the arpeggio window (repeating if necessary to get up to 7 of them).
The black keys then play any in between notes in the scale that are in the
appropriate positions.

Or if you want to specify a complete mapping of all the twelve keys, then
set it to play from "All keys" and then in the arpeggio window you need
to give it twelve numbers for the notes to play.

Always end with 12 for the octave in order to get an octave repeating arpeggio.
But the scale degrees there can be in any order, they don't need to be in
ascending order.

If you want to do a map for two or more octaves, use the same procedure
but end at 24 or 36.

You can also explore using other keyboard mappings from In | Options | Keyboard config
but this will take care of most situations I think. Be sure to ask with
questions! (either here or directly).

I'm planning to start up an FTS forum soonish in order to let FTS users
talk with each other about ways of using FTS - and of course I'd
join in to answer tough questions.

I'll also be doing more work on the help for FTS. Soon also I plan
to add a better search facility to it which may help (it has
one on the Overview page which searches an on-line copy of the help).

Cheers,

Robert
