New lemba example

I was playing around with the "lemba" tuning again (the <<6, -2, -2, -17, -20, 1]] temperament, with TOP tuning P=601.7004928, G=230.8749260) and came up with a little melody that sounded interesting, so I started writing it down before I could forget it. By the time I got to the part where it modulates to G, I'd forgotten the rest of it. But I've got a few days vacation this week, so maybe I'll have time to figure out how it goes.

I did a crude MIDI rendition of it and put it up on my web site:

http://www.io.com/~hmiller/mp3/lemba2.mp3

One interesting thing is that most of these parallel sixths are actually parallel octaves on the keyboard, since I'm using the 16-note per octave DE scale (i.e., two 8-note MOS per octave).

Here's the Scala files I used to tune this, first the scl file:

! lemba.scl
!
Lemba temperament (4 down, 3 up)
8
!
90.92429
139.95064
230.87493
279.90128
370.82557
461.74985
510.77621
601.70049

and the kbm file to set it in the key of D:

! Linear mapping with D = 290 Hz
! Size:
0
! First MIDI note number to retune:
0
! Last MIDI note number to retune:
127
! Middle note where scale degree 0 is mapped to:
62
! Reference note for which frequency is given:
62
! Frequency to tune the above note to (floating point e.g. 440.0):
290.0
! Scale degree to consider as formal octave:
0
