Project Retune: latest MIDI sequences & methods

I've added two new MIDI sequences to my web site, and have posted new
versions of all the others. This revision focuses on holding
continuously sounding notes as close as possible to constant tuning.
This is a game fraught with peril, since some sequences will drift off
the map up or down if not allowed some motion while sounding. But I've
found that the real-life sequences I'm working with can tolerate a lot
of tightening without drifting unbearably.

As before, each sequence is represented in original 12-tET, in 5-limit,
and in 7-limit, the latter two as I have tuned them.

New to the site:
br-pv211.zip: Brahms Piano Variations in D: op 21 No 1, three tunings.
br-pv212.zip: Brahms Piano Variations in D: op 21 No 2, three tunings.

New versions of retunings::
br-pv24.zip: Brahms Piano Variations, Op. 24, three tunings.
br-ps-01.zip: Brahms Piano Sonata number 1, three tunings.
br-ps-02.zip: Brahms Piano Sonata number 2, three tunings.
br-ps-03.zip: Brahms Piano Sonata number 3, three tunings.
br-bal10.zip: Brahms Ballades, Op. 10, three tunings.
sb-imp90.zip: Schubert Impromptus, Op. 90, three tunings.
b-b-b.zip: Bach Chaconne in D- with variations, three tunings.

The above sequences by Bunji Hisamori, a talented performer.

And, as an extra bonus, I have two sequences by the list's own
Jay Williams, used with his permission. Check out the 7-limit version
of Maynight for a JI ride that 12-tET can't even dream about...

As before, my recommendation is 7-limit, even for the Bach. If your ear
won't go along, try the 5-limit version. And please let me know what
you think, either on the list, or private e-mail (jadl@idcomm.com).

Methods update: I've dropped exponentially decaying away drift; it's bad
when tuning must be held in a certain alignment. Each seam has a
desired drift it would like to impose to match tunings on each side of
the seam, and, independently, the segment after the seam has a desired
center tune. These two "argue" and settle for a weighted average, so
that if the seam cares a lot about holding a tuning, it can largely do
so.
