As usual a very interesting post from Kris ;-) I have been thinking
about such matters too but never succeeded to use anything similar
in praxis. In the early eighties I happened to record a radio piece
of Iannis Xenadis (Sandré) that brought me under the spell of numbers
in music. I used to calculate different tuning systems and melody/
scale patterns with pen and paper while traveling but nothing sounded
good and inspired me to really use musically. I only had instruments,
imagination and a four track cassette tape porta studio to try things
out, though. Maybe the mistake I did was to implement the series
tonally? I see Kris is referring to timing in his post.
Anyway, since Echoplex, Repeater and recording software came around
the world has changed quite a bit! I must say that today I like hands-
on experimenting in real-time much more than mathematical
experimental thinking ;-) When recording live into looping software
on my laptop, I like to create midi sequences that re-pitch the loop
according to certain number series. This praxis can easily become
overwhelming in complexity, since what you play will be doubled in
harmony and if you are brave to layer a second line you will soon end
up with four different paths to relate to in your performance. That
is too complex for me, so I usually restrict the real-time
transposing scale to something simple like a quint note circle,
simple octave jumps or a diminished chord (is that how you say it in
English? The chord like for example C, D# and F#). I also have a
whole note scaled pattern, i.e. creating a whole note scale if I
should loop a long single note. What it would throw back at me if I
dared to record a chromatic scale, I don't even dare to think
about!!! ;-)
It was David Torn that, on this list, inspired me to start
researching how to play with dynamically transposed live loops. You
could do that with a Repeater, but starting out with MIDI cc#'s
according to the manual I did not get it right until Bill Walker told
me that it also works with plain MIDI note messages (a tip for you
Repeater owners).
