AW: Looping (what else!) questions..Human Prepared Piano!
Hi Alex,
 
using two identical mics will not minimize what I here 
called crosstalk (yes, I was referring to pickup of the sound from the 
P.A.).
 
The way PZMs work is they do not pickup the sound that is 
"in the air", rather they pick up the sound incident on an interface between two 
media. Putting them on the lid will also make them pick up much of the sound 
coming from the P.A. (but as Andy already pointed out, with non-rock-music 
playback levels, this may not be that much of a problem), while putting 
them onto the soundboard will reduce that effect. And most of the PZMs available 
are omnis (or rather half-omnis), meaning the reproduction of very low 
frequencies is better most of the time (which may not be an issue, simply 
because I doubt that a typical P.A. will reproduce 20 or even 40 Hz properly). 
 
Btw, I have been using SM57s once one a grand piano, which 
will give a very "rock piano"-ish sound. Perhaps you should simpy try the 
microphones you have in different configurations on the baby grands (performing 
your material) and see how you like it.
 
Best,

  Hey all, thanks for the responses, much appreciated :) 
  
Rainer-
With using the two identical mics, how does that 
  minimize crosstalk? (Which I assume is referring to the pickup of the sound 
  that is playing back?) 
As for picking up the fundamentals, I guess I'll 
  just have to try different things and see how they sound..
The PZMs- do 
  you mean literally ON the soundboard under the strings? The only reference I 
  can find on the web to using PZMs is placing one or two on the open lid (which 
  makes sense and seems like it might work.) I'm not sure if anyone I know has 
  some, but I can try.
Andy- 100-200 in US dollars, sorry! And yes I 
  wouldn't need to amplify the actual playing, just the recorded loops...so I 
  will certainly try placing the condenser in a few spots...the only problem is 
  I can't have access to the full grand until the performance!! Maybe once...but 
  I can play around on the baby grands in the practice 
  rooms.
Thanks,
Alex

Hi 
    Alex,
whow, you got yourself into a challenging situation 
    here...
Concert grands have a range which produces fundamentals from 
    16-something up  to more than 4000 Hz. So generally, these low 
    frequencies will be a problem for your P.A., your microphone and possibly 
    your audio interface as well. So I sure hope your composition can live 
    without the fundamentals of the lower one and a half octaves being properly 
    reproduced...
Any microphony which is meant to minimize crosstalk from 
    the P.A. will consist of (at least) two (identical) microphones. The general 
    approaches I'm aware of which also have good properties regarding minimized 
    crosstalk include:
         * two microphones 
    below the soundboard (one on the left, one on the right)
    
         * two microphones above the soundboard.
In direct 
    comparison, the "below" approach tends to have a more "round" sound. The 
    huge disadvantage for your application is that you loose any detail of 
    percussive effects happening inside the piano (e.g. the transients of 
    somebody plucking a string or something), and I believe that these are an 
    important part of your composition.
With the mics from above, a problem 
    in your case is that they might get in the way of the performer when she's 
    playing inside the piano.
Generally, I wouldn't see a good way to do this 
    with the microphones at your disposal. Do you see a chance that you could 
    borrow a pair of half-omni PZMs to be placed on top of the piano's 
    soundboard? With that, you don't have the problem that they get in the way 
    of the performer too much, pickup of sound from the P.A. is minimized, and 
    as they are (half-)omnis, low-end reproduction is usually far better 
    compared to cardioids and the like.
I hope you will be recording the 
    performance (another tricky part...)
Best,
