Out of the Box - Pitch Shifting

Pitch Shifter Values


One of the faults with the PX-1 was that it was hard to understand what Pitchshifter values were as they just when from 1 to 30. Now that I have a PX-2, I can work out what the values are.

I remember reading a couple of postings on alt.guitar-tab about the pitchshifter values. I came to the conclusion that 3 was for an octave down and 28 was for an octave up. After checking with the PX-2, I concluded that I was (indeed) right. The values below show how to program the Pitchshifter on the PX-1.

PX-1 Value	PX-2 Value 	Interval

1		-24 		(Down 2 Octaves)
2		-17 		(Down 17 semi-tones)
3		-12 		(Down 1 Octave)
4		-11 		(Down 11 semi-tones)
5               -10 		(Down 10 semi-tones)
6               -9   		(Down 9 semi-tones)
7     	       	-8   		(Down 8 semi-tones)
8	  	-7		(Down 7 semi-tones)
9	  	-6		(Down 6 semi-tones)
10	  	-5		(Down 5 semi-tones)
11	  	-4		(Down 4 semi-tones)
12	  	-3		(Down 3 semi-tones)
13	  	-2		(Down 2 semi-tones)
14	  	-1		(Down 1 semi-tones)
15	  	-d		(Unison)
16		d		(Unison)
17		1		(Up 1 semi-tone)
18		2		(Up 2 semi-tones)
19		3		(Up 3 semi-tones)
20		4		(Up 4 semi-tones)
21		5		(Up 5 semi-tones)
22		6		(Up 6 semi-tones)
23		7		(Up 7 semi-tones)
24		8		(Up 8 semi-tones)
25		9		(Up 9 semi-tones)
26		10		(Up 10 semi-tones)
27		11		(Up 11 semi-tones)
28		12		(Up 1 Octave)
29		17		(Up 17 semi-tones)
30		24		(Up 2 Octaves)

I've expressed the intervals in terms of semi-tones because my interval theory sucks! I'll have to go back to my theory book and mug up!

Some of the intervals can be used to create some very dischordant harmonies. Try using the Pitchshifter set to 27 or 22 on the PX-1 and 11 and 6 on the PX-2 to create those classic tri-tone relationships! And if you're feeling really sick try using the settings when you play chords!
