[sdiy] Electrolux process explained

[Peter Grenader]

Let me try this again, without just having a triple latte:

The Doepfer A-192 is a CV to Midi converter.  It translates 0 to +5 voltages
to midi signals.  Through a Sound Diver template you can configure any of
the A-192's 16 inputs to be any cc# you wish, out of any midi channel you
wish.  All 16 in may have separate settings in real time.  The A-192 is
nothing more than one of their pocket dials with the encoders replaced by
mini jacks.  At the point, you can use analog voltages created in any way
you wish as pots.

So what I did was assign the analog gear via the A-192 to attack different
parts of the Nova's and Q's midi implimentation list.  Being fairly new
instruments, their midi implimentation runs deep.  Not the case with the
Yamaha 802.

The most prominant use of the A-192 in Electrolux was creating the bulk (not
all) of the doppler effects heard in section 2.  An unfortunate 'feature' of
most midi instruments today is the effects all have their own control LFOs
and you cannot sync them with the other LFO's in the box or anything else,
and forget getting any of those out of the instruments to control something
else.  So I would use the analog gear to create a universal control  so that
the amplitude, pitch modulation and panning all tracked one another - thus
giving very realistic effects.

While the doppler was the most prominant, the analog gear was used all over
the place.  Another good example is the filter modulation of the voices in
the coda.  All of that control came from analog gear.

Another use of the analog gear was actually creting midi notes.  This was
done by wiring a Doepfer MTC64 keyboard controller board firectly to the
outputs of one of their VC switches.  The switch would gate the common
ground signal coming from the keyboard controllerdirectly into one of it's
64 key inputs.  So, everytime the enable wnet higher than about 3/4 of a
volt,  the VC switch would close and the midi stream would think a key was
depressed.  This is how all of the notes of the coda were laid down.

There is no instance however when you actually hear analog equipment.  At
the time I only had control modules - nothing that would go into the audio
range.

I make this comment because a while back there were some write-ups onthe
list about virtual analog filters from digital machines.  While there were
numerous problems to overcome to do my (basically analog) schtick on this
equipment, the filters were never one of these.  This is why I like the
Analogue Systems Multi-mode filter so much, because it behaves much like the
one in the Nova, which IMHO is excellent.

hope this helps give a little insight.  I'm telling you, modern analog
modelling equipment CAN replicate large modulars with a little help from
their friends!

best,
Peter
