Another good idea.

I was thinking the other day about an idea for a software tetrachord
finder. If I were a programmer (hint) I would devise it as follows. A
rectangular window with two sliders and 1/1 at one end and 4/3 at the
other. You set one of the sliders along the rectangle and a little
window box tells you how many cents along the 1/1 to 4/3 line you are.
Same with the other slider. And you can view the cents between as they
change in real time. The clever bit would be to have all this in ratios.
A clever programmer would then do an extension for pentachords. Just an
idea.

Regards.

Alison, if you look in the manual for my tuning program
LMSO which I confidentially sent you last month, you will
see that it does something extremely similar to this.

Set the Repeat Ratio to 4/3 and open the Interactive
Quantize window. Set the IQ % to 0% so you will see the
*current* values in the display. You may want to turn off
'Show gradients' in the Preferences window. Choose ratios
or cents for the graphical display, as you wish, then edit
the Scale Pattern in the Scale Oven's Recipe in cents or
ratios. Probably best to set the mode to Absolute Cents
values so that your edits of the in between notes in the
tetrachord will react linearly to your changes. Just place
the cursor on top of the interval you wish to graphically
edit and use the up/down arrows on your keyboard to move
the note. You will see the change instantly in the
graphical display.

By the way, I consider this nonobvious invention
proprietary and anyone who steals it is asking for some
serious ass kicking.

All the best,

- Jeff

Something else that JustMusic is supposed to do... someday.

Can I get a commission for bringing it to everyone's attention? ; - )
