The software update to the Synchron pianos player was fundamental to me. I struggled to enjoy the Bösendorfer Imperial (BI) before the update. I think it was partly because the MP11SE has quite a light action and I found it really hard to control the BI.
Being able to make my own velocity curve really changed things for me. I also think that I would not have enjoyed the VC280 without the update which I got around the time of the update.
I am constantly switching between three VSL pianos now (BI, VC280, Blüthner). Sometimes it will just be one for weeks on end, but then something changes and I switch to one of the other 2. But mostly now I switch between the three of these within one practise session. I love them all for different reasons.
The BI is the most even of the three, I am most likely to get a decent recording of something I'm working on with the BI because it is even across the keyboard and I've got the velocity curve right. I feel the BI works for everything and I love its deep rumbly base but it lacks that idiosyncratic sound to give that something extra special.
The Blüthner has the least dynamic range and it takes the most work to bring out dynamics with it, I've wound up the settings in the Synchron player for my usual configuration to maximise dynamics but it is still hard work. But I love its distinctive sound and I've played it a lot recently.
I love the VC280's punchiness. You can nicely pick out a melody line using the VC280 and it has a lovely sound. My one grumble with it is as ha been reported here before is there are some bass notes which produce an unpleasant sound when sustained and this sound sustains longer than expected. David B mentions it here. http://forum.pianoworld.com/ubbthre...-sendorfer-280vc-review.html#Post3129686
There are some of my recordings where it really does stand out.
