1800.0. "Absolute vs Relative Realism" by MUSKIE::ALLEN () Thu Dec 08 1988 20:02

    	This may already have been a COMMUSIC topic, but since I didn't
    see it, goes (and feel free to move it).
    
    Chad brings up a good point in 1796.28, that many sounds that come
    from our toys sound less than lifelike when heard on their own.
    However, most of these when heard in the proper tonal and rhythmic
    context come across well.  There has been a lot of discussion about
    realistic drums and guitars and whatever.  (I am guilty of just
    finishing a response where I beat on the U110 for not having a 
    "realistic" enough piano).  But the more I think of it, this situation
    is analogous to that in another vice of mine: Audio equipment.
    
    For years, I searched all over for that elusive quality of realism
    in sound reproduction.  It took me a long time (and many ducats)
    to realize that I would never be able to simulate having Carnegie
    Hall in my 10' x 14' living room, no matter how big the speakers
    or how powerful the amp.  Physics and EE were working against me.
    That is not to say that I could not achieve an exciting sound, or
    if the music called for it, a soft, mellow atmosphere.  It just
    meant that there would always be a qualitative difference.  
    
    In buying MIDI toys, I am trying not to get too hung up on ABSOLUTE
    fidelity, and concentrate more on the RELATIVE sound of things as
    they come together in the mix.  That is a major reason I could live
    with the looping on the D110's cymbals or the lack of realism at
    the tonal extremes on the K5's piano.  When I get them mixed and
    add a touch of reverb, they don't sound half bad.
    
    What do other people think?

    I don't hear lots of real instruments, I hear lots of recordings.
    THAT is the sound I want to put on tape.

Bill,

I agree with you completely about SGU sounds in and out of context.
I am working extensively right now developing sounds for the EPS. I have
found that the hardest instruments to get sounding good on a sampler are
horns. I'm still not satisfied with any trumpet, trombone, or sax samples,
even on the EPS. The tuba is an exception. Piano
is probably the hardest keyboard instrument to sample. In the case of the
D110, the onboard demos show how great it can sound when the instruments
are in context. By themselves they sound fair IMO. If I can get a sample
to sound really good or great by itself, I never have to worry whether it will
sound good in context with other instruments. I'm very interested in Len's
opinion on how to get more realistic drum samples? I have an RDAT and two
samplers. Any drummers ready for some serious percussion sampling? Len? Butch?

1800.3Mush Mix hides Bush Lix ?SALSA::MOELLERI'm NOT the NRA, and never will be !Thu Dec 08 1988 20:3922
    I have had the bizarre experience of being told that a REAL flute
    part on one of my taped pieces, was a synth, and later that a
    sampled flute part on another of my pieces must've been real.
    
    There are certain sounds, like kettledrums, where their real tonality
    and dynamic range would blow out your speakers.. so there necessarily
    is a tonal and dynamic compression required to sample some sounds
    successfully. (say that fast 3X).  So even good samples depart from
    'reality' in many ways.
    
    And of course there are tricks like reverb/delay/EQ that can make
    certain sounds work in an arrangement, even though they suck when
    heard in isolation.  HOWEVER, given a choice, and the $$$, I'd rather
    the sounds sound GOOD in isolation, which gives them a much BETTER
    chance of sounding good in an arrangement !
    
    And I certainly wouldn't buy a synth with inferior sounds, trusting
    that I could hide it in the mix !  (not that anyone's pushing that
    concept)  You can't 'hide' anything in a mix !  Not from discerning
    ears, that is..

    AMEN !  it's the temporal envelope changes that get you, along with
    the many possible attacks.  
    
    Another issue is that you can get a good horn sound, solo or ensemble,
    and still have it sound like crap in an arrangement, because horn
    harmonies are generally spread out more, have wider intervals, than
    keys or strings, and real individual horn lines in an arrangement
    use a lot of sliding from pitch to pitch.

1800.5DNEAST::BOTTOM_DAVIDEveryday I got the bluesFri Dec 09 1988 11:0120
    some of this has to do with the purpose of your recording. At one
    point I was not very fussy about the recording, the mix or the
    performance as it was just scratchpadding. I wanted a tape I could
    hand a band and say learn this. With a 4 track and minimal midi
    one can't do alot more and still maintain hi-fidelity. However,
    I've changed slightly in that I finally achieved what I consider
    to be a damn good sounding tape/performance/mix (CM VI) thanks to
    extended recoding time, new toys and a hell of a lot of patience on
    the part of myself and my wife :-), halfway through the project
    I rearranged the piece to acoomodate a 3:40 "top 40" mix....just
    to see what'd happen. Now months later I find the context of the
    drum program just doesn't change enough to be realistic anymore...
    Time often has a way of changing your mind about a sound(s) I guess.
    Not being a sampler weenie or much of a midi weenie doesn't excude
    one from the problem, I primarily use real instruments and still
    find the need for extraordinary care in the recording process,
    particularly vocals when done with a stage mike...eq the daylight
    out of them just to get a fair sound...

re -.*

Some ideas I've been developing with regards to sampled horn realism...

Generic

o make sure that song arrangement uses each horn part within the instrument's
  normal range

o vary the attacks and articulation between notes as close to a real horn
  player as possible; this can be pretty difficult on a keyboard

o pitch bend can be used effectively but is difficult to control with a wheel
  or lever; the timing, range, and speed of the pitch bend are critical for
  realism, and eat up lots of sequencer memory with MIDI continuous controller
  events; these can be "thinned" out somewhat but it is time consuming unless
  using a MIDI filter

o aftertouch vibrato is very nice for expressiveness, the rate of vibrato is
  critical for realism; I've found that on the EPS, an LFO rate of 34 is just
  about right

o the EPS seems to have the best player controls for emulating a real horn
  player's style; the 4 momentary patch select combinations, pitch and
  mod wheels, plus poly-aftertouch allow very flexible (although somewhat
  foreign) control of the many expressive parameters of a real horn

o all of the horns seem to sound alot better with lots of ambient reverb
  added in the mix; that was part of why Harry James albums had such a "fat"
  trumpet sound, not to mention what a great artist he was

Trombone

o large mouth piece; requires lots of wind; relatively slow attack; lots of
  sliding between notes (naturally); not so much variety in styles; bass clef;  
  lower range, used for horn section "padding" more than solo; provides lower
  register foundation along with bass trombone and bass and bari sax.

Trumpet

o small mouth piece; requires excellent "chops"; used extensively for solos;
  wide variety of attacks and articulation...blats, mutes, drops, gliss, glide,
  quick arpeggios, pitch bend,etc.; sounds "thin" in mix without lots of reverb

Sax

o seems to be the most difficult; the reed adds so much more expressiveness
  and the keypad lends a whole new aspect to performing; it is pretty strange
  to a primarily keyboard player to have to press down 8 or 9 keys to get one
  single note; wind controllers like the WX7 (I was kidding about Yamaha) and
  the DH100 seem to have potential; I won't be satisfied until I can get that
  "LA Law" sax sound which may be an elusive dream...

1800.7or was it the Lonely Sampler ?SALSA::MOELLERI'm NOT the NRA, and never will be !Fri Dec 09 1988 14:5516
    re horns..
    
    I just completed a quick piece that features a trumpet solo.  If
    I get it onto a cassette in time it may be on Commusic VI.  I
    have lots of trumpet sounds available between the Emax and Kurzweil.
    Ended up using a Kurzweil sound, just like .0 said, one that sounded 
    junky in isolation but worked well in the mix.  It uses a delayed LFO 
    for vibrato, the only problem is that the LFO rate is always the
    same.  Slightly synthy.. but I use plenty of reverb and a stereo delay 
    patch on it.  The Emax has an LFO 'variation' mode, (vary the LFO 
    speed/depth within limits) but no amount of tweaking gave it the 'this 
    is a human being' vibrato.
    
    The piece's working title is "The Aerobic Bull".

        Hope you get it in soon... we're onto side II now.
    
    re: saxen
    
    
        Being an EPS owner, I have to agree with Dave Orin's summation.
    I think I'm getting better at emulating a saxophone, given a decent
    sax sample, lots of practice with the patch buttons and aftertouch,
    and still more practice on the DH100 to figure out where to "breathe".
    
        A piece demonstrating this will be one of my submissions on
    VI. Not perfect, but....

1800.9No SecretsDRUMS::FEHSKENSFri Dec 09 1988 16:0334
    Recorded drums don't sound anything like real unamplified drums.
    I agree that for most people the reference is the processed studio
    sound, not the sound of a live acoustic kit.  The overall balance
    between instruments is different (the cymbals are much more obvious
    in a live situation), and the tonal balance within a single sound
    is different (toms and snares are given much more "fatness" and
    low end in the studio than they genrally exhibit live).  This is
    why sampling drums is such a difficult problem.  And, no, I don't
    have any hints, suggestions or secrets.  I record exclusively with
    drum machines, with a little EQ and reverb to sweeten the raw drum
    machine sound, and am quite happy (even as a drummer) with the sound
    I get.  Some of it may be my drummer's instincts showing through
    in my programming.  With only 4 limbs, real drummers tend to be
    less "muddy" than unconstrained amateur programmers.
    
    I agree with Karl that, even though the mix does hide some deficiencies
    in realism, you shouldn't depend on it.  Use the best source sounds
    you can get your hands on.
    
    Also, "muddiness" or "lack of clarity" in a mix usually means that
    the sounds' frequency ranges are stepping on one another.  When
    arranging, I try to voice parts so they are working in distinct
    octave areas, and only overlap when I am deliberately "doubling"
    a part or layering voices.  I also EQ things so they don't get in
    one another's way.  You have to use EQ sparingly, otherwise you
    get an obviously hyped up unnatural sound.
    
    Finally, the recording gear you use will have some effects.  Third
    generation pingpongs on a 4-track cassette deck are not going to
    be as transparent as first generation tracks on an 8-track 1/2" 15ips
    recorder.
