thank you for your kind reaction. I'll try to seriously answer your questions:
1) "did you play"?
Honestly meanwhile I studied Piano with pretty good Profs in Austria, I currently "play" on my Piano daily at home but just for my personal fun. My personal Opinion is, that when it comes to produce recordings, we could work that much more reflected, detailed and prezise, with using the technic we have today than with trying to do it the old comparable clumsy and unprezise "craftsman" way which is so much distracted from the essential musical decisions, by tons of for us completly overcome "technical" limitations . So I always start from clean mididata which I always creat directly from the score to avoid any unnecessary additional data which is not part of the score. Than I do what I have learned while studiying the piano: reflecting and shaping each very moment of the piece.
2)"was it a playback from a MIDI file"
You have listened very attentive👍 Meanwhile as I already described all of my recordings (at least since 2008/2009) are always playbacks of "pure" mididate which I edited to give them my interpretational intention for this certain recording I am still searching for the right Piano-sampleset to do those pieces.
Yes I started to work on those pieces with the Synthogy Studioo Grand when they were out, but in some aspects I felt the piano was not that much intended for the needs of this kind of music. I adapted that recording later on the Bechstein-digital which seemed to me in many aspects one of the outstanding well done recent Pianosamplesets on the market (meanwhile it is a Bechstein: yes it has perhaps a bit more characteristic personality in its tone - I always can recognize a Bechstein even if it was simply a Samplesets - but this brings in a few aspects of the avilable palette of colors reactions which are not as warm as I would expect it from a good Steinway) So indeed I am still looking for the ideal Pianosound for that piece.
But yes I worked much more detailed to adapt my interpretation on the Bechstein, than I did for the Yamaha. Meanwhile when working with the Bechstein I was already surprised how much of the tonal decisions of the Studio Grand were likewise apliable for the Bechstein. For the Yamaha-Version I confess: I was not that eager to individualize my interpretation. Since sorry it is a Yamaha: everything is well done and good balanced the overall sound is good, but.... I personally feel this it still not the Piano which would realy replace my current Bechstein-Version. This is explicitly just a matter of my personal taste and definitly not a matter of Quality, (which is superb as usual - or even more - when it comes to VSL-Products).
If the Synchron Steinway brings us, what can give a Steinway such an outstanding Pianosound, Than I probably would not hesitate to spend the work to seriously adapt this music in every detail forr a final version. But this is just my personal opinion. It is the Problem I personal do have with Yamaha: good but without the moment which unfailable touches me in a good Steinwaysound. Thats why you currently get only a rough adaption for the Yamaha. If the Steinway inspires me more I'll spent of course more work to get the best out of it.
