I'm considering purchasing the Synchron Steinway and am looking for some feedback on specifics from people who use it and have a good ear for the piano.

The most common issue I have - creating very sparse, closely mic'ed and dry (in terms of reverberation) music - is finding a piano library that adequately emulates the effect of playing a note twice or more in close proximity, and trilling. 

I have a feeling that when one trills two notes in close proximity on a real piano that the closely resonating strings influence eachother and the sound is affected in a way I have not found captured in a library.  Also, when playing a single note extremely fast, or in very close proximaty to it's previous iteration, - especially if the felt hasn't dropped - there is a change and fluxuation in sound created in part by the resonating string being restruck, I find that this usually goes unaccounted for.  I've read that the VSL Bosendorfer has an algorhithm to account for this, does the Synchron have an algorhythm or some other consideration?  With pedal and without pedal - how is the same note played in close temporal proximity to itself heard?  Does it sound like the real thing or two samples being triggered one after the other?  How are the trills?

Also, is there the possibility to generate keynoise or approximate somehow a close micing near the keys?

I'd be curious to hear feedback on any of these points.

Thanks for the offer, bbelius.  I don't have any midi files specifically, I had just been playing through some libraries last year and basically gave up on finding one to actually use.  Hearing any sparse single note melodic passage of any variety on the Steinway D would be helpful, if anyone is interested in posting an on-the-fly single melody with some trills and repeated notes that would be a great gesture and really helpful.  I just lost a hard drive and don't have a setup.  I would want to hear how it sounds dry, close and laid bare on a single line with repeated notes, trills, etc.

I'm not personally interested in the Yamaha sound, but thank you again for the offer to post a sound sample.

It's not with close mics, but the Tchaikovsky demo I made has a ton of repeated notes.

Nice to hear from you! Congratulations on your new Steinway! I hope you enjoy it as much as I do!

Thanks for the additional feedback, karvala.  I'm looking forward to using it once I have a machine ready that can handle it!
