(idm) DSP, digital tools, Autechre

Another thing (besides software-controlled DSP sound mangling) that
Autechre has done a lot of is layering subtle amounts of audio-rate
modulation of their pure-tone synth notes, making much of their recent
melodic parts have that gamelan "raspy bell" sort of tone. I'm not sure if
they are using a Nord-mod type of synth, but that would be the kind of
digitally-accurate tool to give such oscillator cross-modulation. In
contrast, I have not heard many pure single oscillators (unmodulated, in
other words) involved in the melodies of Chiastic and LP7.

I think that, very much like with FM synthesis emerging around '84, new
timbral possibilities lead to a lot of exploration and few people master
these tools right away.  There are a lot of records coming out with use of
certain kinds of complex computer-based editting (time stretching with
artifacts for instance) which doesn't always work beyond being sonically
interesting.  If you go back to records from 83, 84, 85, 86 and look at
how everyone jumped on the latest tools.  One year there is a dx-7 all
over the record, the next has a linn drum, the next year a sampler or
Fairlight...  After a release or two, the use of the tool tames itself in
the mix and is more used for what it does most interestingly, not just
wantonly.  Later tools like cheap dsp-based gated-reverb, multi-timbral
samplers, (even later) time-stretching on samplers and the resurgance of
vocoders (cheap ones just recently) are all further examples.

I guess what I'm thinking is that these new tools (synths that make
complex synthesis easier to program, and digital-mangling filters in
software) are likely to go through a phase similar to what earlier tools
emerged through.  I think that Autechre is being pretty careful, but are
following these new tools very closely the last few years.  They
apparently have spent a lot of time with older tools (606, Juno 106, FM,
and EPS sampler) for quite some and made some innovative music, so I could
see why they would demand more from their tools after a while.

However, being someone who makes his own experimental electronic music, I
am somewhat weary of making an entire album that is based on following the
exploration of a brand new piece of technology, because that idea makes me
think that I'd be setting aside a broader thinking process for basically
some immediate gimmick factor...if not just unaware of the soon-to-be
recognizable range of sound that that tool makes.  It is kind of analogous
to when cadmium pigments where first made available to oil-painters in the
early 1960's--a painter could run out and buy a whole new pallette of
alien artifical colors, but those old organic colors might get left out of
those first few new paintings... and it would be apparent to the artist
later on that those paintings were out of balance and where just concerned
with the process of familiarization with those new colors.

Back to music...

FTR, I do like Chiastic Slide and LP7 for their careful and sparse melodic
moodiness.  I think that their melodic approach has become more efficient
over the years and they use fewer melodic tones and layers to convey the
same kinds of moods.  The percussion and melodic roles the sounds play
seem to have merged a lot since Amber.  Too bad they got so upset on the
list; they really ought to develop the personal mechanism to deal with
listenning to their own fans talk about their music without getting upset
that their fans still may not understand their intentions, efforts, etc.
