All you need is a keyboard. This is always more flexible than recorded or
computer-performed demo, and may even be better than pitch tracking with
visual feedback (keyboard is audio feedback). Keep in mind pitch tracking
doesn't work on multiple notes at once, and there's no way to isolate each
part of a good ensemble to individual tracks (maybe clever close micing
under certain circumstances), since they need to hear each other during
performance. Michael Zarky has a very good pitch tracking program. Email

Yes, somebody else pointed out to me that my message made it sound like
your modem was connected at 42K *bytes* per second. I didn't mean this,
and my calculation is correct.

I don't know if this is universally adhered to, but I've generally seen a
capital B to mean bytes, and a lower-case b to mean bits. So, for example
42Kbps would mean 42K bits per second, whereas a 100MB Zip disk holds 100M
bytes.

Yes, you're right, it would be more flexible for rehearsals. However I've yet to
devise an elegant scheme that would manage a scale that has two E flats, two A
naturals and a separate F sharp and G flat using only a conventional 12-tet keyboard.
The problem is to map a 13 note scale on a 12 note per octave keyboard.

1/1 C
8/7 D
7/6 Eb
6/5 Eb
5/4 E
4/3 F
7/5 Gb
10/7 F#
3/2 G
8/5 Ab
5/3 A
12/7 A
7/4 Bb

The most elegant solution I can think of is a 12-tet keyboard which has two playing
modes; one to access the major 7th chords on one diagonal of the diamond, the other
to access the half diminished chords on the other diagonal. There may be a more
elegant solution. The ultimate solution of course would be to use some sort of
generalised keyboard like the microzone (are these available commercially ?)

you could just have the extra notes in different octave if you had a microinterval synth
that tunes every note seperately so that octave(tet) #1 say 128 to 256 would have a
6/5(tet) and octave(tet)#2 would have a 7/6 and octave three could have a 51/40 and
octave four could have a 100/81
happy tets
