analogue vs. digital - emporer's new clothes?

From an interview with Mr. De'

"Do you think you are sacrificing sound quality now that
you are exclusively digital?
Being an engineer I know the difference. It’s a
mathematical difference as far as analog and digital is
concerned. But can you really hear it? I think not. And we
are still getting better with higher sampling rates and
stuff.
If you bring up a real Prophet 5 and a Pro-53 and you put
them right next to each other, the Prophet 5 may sound a
little warmer. But if I take the Pro-53 and roll a little
bass on it and put a tube amplifier on, it is not going to
sound any different - and people are realizing these things
now."


So, do you reckon there is much difference between the two
now, in terms of sound quality (as opposed to
detuning, etc.)?

there is no sound quality difference in the finished
recorded product, but not in terms of one sounding better
than the other, now live, i am betting the analogue stuff
has more depth to it, the way that a live instrument may
sound vs recorded- where as digital has that produced
synthetic sound, preprogrammed and all.

oh well.

A/D converters do the thing.

Analog stuff is more fun to use. And analog equipment smells
cool as well.

I have no idea who this mr. de' is, but if he used classical
instruments (piano, guitar, and so-on) in his music and now
uses softsynths, there is a world of difference. Analogue
modelling synths are getting better, but still have a way to
go before they reach the real analogue ones... and.. running
it through a tube amp to make it sound analogue.. well..
he's just adding the analogue sound of the tube amp, not
making the original sound sound analogue...

(oh, and a question for you.. it could probably be in that
huge numark matrix thread, but... am I supposed to oil the
crossfaders on my mixer? it just occured to me that this may
be something I'd want to do, but the manual says nothing
about it...)

Some people clean them (Dave_g will be able to point you int
the right direction), I used to with my old PMC-270 fader,
but it added so little life to them that it became
cheaper/easier to just replace them when they started
bleeding. One of the reasons I got my current mixer is that
the faders are meant to last for 7 years (assuming 1 hours
use, scratching, a day). 18 months later and it is as good
as new.

Mr De. used to use a piano, mainly though, he's refering to
analogue gear.

haha.

have you tried any of the arturia's soft synths like the arp
2600 or minimoog?

The arp 2600 is amazing.

with analogue the quality is in the warmth - and the
shifting nuances in the harmonics

digital is great too though for sheer purity - i like a
combo of them both - horses for courses so to speak

Fair comment, but even a great softsynth with a nice MIDI
controller isn't as enjoyable as a lovely analog beast imo.

Plus softsynths aren't liked by my computer. Mind you, my
computer doesn't seem to like anything.

I think the softsynth manufacturers ought to add a "playing
up" button, which, when on: they detune the longer you leave
them on; sometimes hum mysteriously, when saving a pattern;
you get very faint glitchy noises if you listen carefully,
etc.

Bugger, I forgot to mention I can't remember what I used to
clean it, may have been meths, but I'd check before doing
it.

detuning was a huge problem in the begining,cos a band would
have an concert in a big hall and the heat from human body
would detune the oscilators.

that was quite fucked up.

what happened with your fader...does it play weird
cracklings?

ceri: will do.

plaster: no, nothing wrong with it yet, but I was just
thinking that all things need maintenance, and that there
probably was something I should do even though the manual
doesn't say what... I read somewhere about some guy who used
vaseline to make the faders go smoother, but that doesn't
sound like a good idea.. I was just thinking I should
probably oil or clean it or something...

where do I clean, btw? I can take the fader units
out, and I don't really see a place to clean other than the
surface...

the mixer is a vestax pmc05 proIII.

ah,thats nothing hard,but if you think that ur work might
damadge the fader's slider,then don't do it alone.

basicly,you open the mixer and with an small screwdriver
slightly remove the metal bearing which holds the slider
together.
inside that i will see a brown plastic plate which is
necesary for applying volume when you move the fader.

moist a piece of cloth with alcohol and rub a few times on
that untill it's shiny.

that's all,but since you have a vestax mixer,better send it
to someone who knows its way around.

Yep, I'd take the faceplate off and remove the fader from
mixer entirely (most PMCs, you can disconnect a little white
lead, looks a bit like a PC internal power cable and then
lift it out). That way, if you do tip oil all over the shop,
it's only the fader that needs replacing.

Ok mr master, here's what you do. Take the faceplate off the
mixer. use a pozidrive screwdriver (POZI not PHILLIPS!!!).
Take the crossfader out of the mixer, again use a pozidrive
screwdriver, there should be two screws holding the metal
panel on the mixer, then two more to take the panel off the
fader. (thats assuming its like its little brother the
pmc06).
Detach cable.

Now, the crossfader should be in a little metal box, with
holes in the side, which I assume are for oil. BUT its best
to open the box so you can clean the tracks as well.

use cutters to cut the thin bit of metal where the side of
the box is soldered to the circuit board.( it isnt needed)
Use a flat screwdriver and carefully prise the box.
The first time its trickey, but remember to be careful and
not to distort the shape of the box too much!!

Ok, the little box is open and inside there should be about
4 thick dark tracks and a big block with metal prongs on two
metal rails. Add oil to the rails. I use singer sowing
machine oil, but something like that will do. basically
clear lubricating oil, not thick engine oil(I doubt you
would, but just in case, don't!!)

The fader should move a lot smoother when you have the oil
on there. Clean any excess with a bit of kitchen roll,
tissue, etc.

Get a cotton bud, like the stick with cotton on the ends for
cleaning ears and dip in meths. Carefully rub the dark
tracks avoiding the delicated metal bits on the moving bit.
clean along the tracks and black stuff should come off.
Clean them a bit, a few rubs up and down to get the large
amounts of dirt off. Clean any bits off the tracks and
rails. make sure no oil has dripped. snap the case back on.
add the bit of metal, plug cable back in and put into
mixer.

Should be a lot better. Do this once a year or so, or
whenever you want a supper slippy fader :D

Does that make sense?

analogue superiority doesn't lie in the intrinsect "quality"
like noise floor, frequency range and all that...

but in the fact that you don't have a/d conversion which is
90% of the time where you lose quality, and more important,
no aliasing whatsoever

the best thing to do is to test the filter of a analogue
synth and one from a software: put the slowest lfo you can
to sweep the filter with the resonance to the max (btw try
to find a vst with a decent emulation of an analogue filter
in self-oscilation and then show it to me because i'm still
searching...) and listen closely to the sound with
headphones. (better not put it trough your sound card or
anything not necessary in the signal path)

then do the same thing with the vst emulation (or a vst as
close as possible to your hardware synth) and you'll clearly
hear what i'm talking about

Wouldn't oil leave a residue buildup over time?

I usually spray contact cleaner into the fader, it gets rid
of carbon buildup and works a treat if you are getting bleed
through or crackles. You can find it in most electrical
shops.

Yeah I have never dismantled the mixer and removed a fader
to do it.....The stuff I buy comes with one of those long
directional nozzle things, a bit like a straw.

Just spray some into the gap whilst moving the fader side to
side, you will feel it loosen up straight away.
