The "piano in the room" sound

I'm relatively new here too, so I offer my small 'Welcome!'

With regard to the complexities of creating a 'piano in the room,' I'll leave that to the experts. I just wanted to comment on the image you posted ... where do you put the music? I can see no music shelf/stand...

Stig,

Thanks for the comment. I believe that one of the issues highlighted is how mic placement captures artifacts from resonances, reflections and standing waves that are just reproduced is the sound system.

I am keen to discover how this impact changes when you go from individual samples to a modeled piano. Perhaps they include the mutual string resonances which are missing in samples. But in both cases, there are still 1+ mics in finite locations and their associated artifacts.

I hope to also explore the relationship between mic location(s) in the modeled piano and speaker placement(s). But maybe a diffuse/multi-channel sound source with natural room reverb will be more important than any correlation between sound source and mic placement.

Hello again, I forgot to tell this...

I said I don’t know much about these things, although I tried to learn things at that time I was comparing speakers. I was wondering why my friend said these sounds good, when my ears said not good?
Could it probably be a differens comparing speakers with listening to a real piano or listening to a recording of a real piano? And hearing a difference is not necessarily same as one being better. And standing beside a real piano where the sound come to both ears, maybe not at the same time, and with  that rooms acustics, not at same time to both ears - or listening to a piano from a CD? Which speaker sounded as a real piano? None of them came really close…..to my ears.
In speaker listening, the speakers are usually positioned so that their angle to the viewer is 60 degrees. An equilateral triangle is formed. And In order for us as listeners to get the right sound image, we tried to sit in a fairly well-defined area, symmetrical to the speakers. But I gave up. Was not satisfied. At that time I was thinking there is no ”one” right speaker, we are all different and hear different. Speakers can sound different in different ear canals, earflaps, and the size and shape of the head can have effect on how one feel it sounds…and room acustics and so on…..
So, I’m using headphones now. partly also because I live in a flat, third floor.

You are looking for/creating a real "piano in the room" sound. Bravo. I think I don’t buy speakers before this your journey show something better than what I have listened to so far 
Thank you,

Stig

Great note back to muxelles, Qexl. 

I am interested to hear as well how things 'get on'.  One day I will take the leap and apply the transducers to my piano's soundboard.  ;-)

I have a real baby grand shell that I have a Casio PX3000 I use with Pianoteq in a MacBook pro in and always trying different speaker set ups... ...some aimed at me and others sometimes on or just above the sound board ( metal frame and strings removed)... can never get it right, but looks cool... I sometimes rolled it out by my pool for parties and use a PA.

All excellent questions.

I thought that I would 'knock around' with a rubber mallet before placing my transducers on the soundboard in order to find some near-nodal points.  I tried to understand it by looking at the underside of a Yamaha TransAcoustic, which both has transducers and a real set of strings, but I didn't make any brilliant deductions.  On my old Steinway upright, I know that the transducers will have to go on the back (the non-string side), which also means that their position will be limited to fitting between the upright ribs of the case. 

I also intend to be somewhat non-destructive, mounting each transducer first to a rigid block and then using hot-melt glue to attach the whole to the soundboard, as hot-melt glue is [theoretically] removable with alcohol.

This is a project that I keep putting off for other things, such as doing laundry, etc.!

As for how to position speakers around a piano keyboard for realism, I mounted larger speakers to the left and right of the keyboard on stands facing the ceiling, making sure that the speaker cones are near keybed-level, but positioned such that the player's ears are shielded from direct transmission by the upright 'walls' on either side of the keyboard.  This worked well for the mids, but not for the highs, so I added a smaller set of speakers facing the player's ears, but potted-them down so as to just add the missing treble detail.  Furthermore, I placed an 8" subwoofer under the keyboard to the left for some bass support.

Sounds pretty real, especially on the 'model' presets (...like the Petrof 284 Mistral preset, etc.  The 'Player' presets are pretty close as well.).
