Hi dklein
Here's what I can tell you about the stereo image in '' player '' and '' recording '' mode:
If you want a coherent stereo image in "player" mode, you must logically place a microphones stereo pair in ORTF configuration (spacing 17 cm, approximative distance between the two ears) in front of the keyboard, at the height of the ears in Pianoteq. Then, to transpose this stereo image into the "real" world, I think it would also make sense to place your speakers in front of you at a distance of at least 1 meter (ie, the distance between you and the middle of the soundboard). The spacing of your speakers should be between 1 and 1.50 m.
However, this is not so simple if you want a realistic stereo image. It seems impossible even with two speakers in front of you, because when you sit in front of an acoustic grand piano, the sound does '' not '' come directly to your ears, but leaves the soundboard, to the right, bounces off the walls, and then returns to your ears on both sides of the room, with a very slight delay.
In other words, I think when you use Pianoteq in player mode, with speakers in front of you, you don’t have to look for a realistic stereo image, but rather a nice stereo image to your own ears.
I think your reasoning, by wanting to place the microphones in the same place as your speakers in relation to the keyboard is very interesting, but can’t reflect the reality anyway. This is only consistent with the transposition (virtual miking / real monitoring listening) you want to do.
The only possible realism in player mode would be that Modartt build a physical grand piano with loudspeakers at the location of the soundboard, as on some Clavinova, for example.
I really hope that Modartt will do it one day, or that Yamaha will be interested in integrating Pianoteq into its high-end digital grand pianos.
Regarding the ''recording'' mode, this is totally different, since most commercial recordings place the listener sitting in the room, as if he was attending a concert, not as if he was at the pianist's place (although it sometimes happens deliberately).
This is my opinion on this subject, but it’s very interesting and I think that thanks to your reflection we will soon publish an article to illustrate the different possibilities of creating a coherent stereo image in player mode.
Thanks very much for your interest
