I wrote this last night, listening to the files through my AirPods. I just re-listened to them through my HD-650 and while my comment still holds true, there's this noticeable difference in volume levels. You should have normalized all files. 2 and 3 are too loud compared to 1.
I think the 3 is even nastier through proper headphones. 1 is a slight bit too clean and dry but it seems to respond best to dynamics and the soft timbre is most to my taste. 2 is not bad in terms of timbre but there's something wrong with its dynamic response, it's too sensitive and jumps out unnecessarily loudly and that ruins it. Also I think the reverb in 2 is not very well done. Judging from the proper dynamic response in 1 and very unnatural dynamic response in 2 and 3 I would assume 1 is your digital piano's internal voice, whereas 2 and 3 are VST-s and you need to rethink your velocity touch settings.
Kudos CG - I don't know how you do it but you do have a knack picking these out...
1) was built-in CFX sound of P515 (played on P515) - with edited paramaters: Concert Hall/Reverb 15 - recorded to USB (and transferred to dropbox)
2) was VI Labs Ravenscroft 275 (played on SL88 Grand) - with TW Hall Warm/Reverb 20 - recorded using GarageBand DAW (no other added effects bar a little compression)
3) was Steingraeber E-272 using the Venue Reverb from the Ant. Petrof Venue preset - recorded directly to PTQ (end exported as WAV)
I have learned a little something from this, the CFX with the P515 is probably the best combo I have, in terns of sound/action/eveness ratio to the SL88 with the VSTs but I still don't understand why the P515s USB recording does not produce a decent output volume, when I play it over speakers vs hearing it back is lacklustre in comparison and just doesn't do the playing any justice whatsoever.
Quick question, is the answer to normalise the recordings and if so does that not affect the dynamics of the performance or should the gain be used instead? Other recordings of the P515 especially on YouTube are so much louder with clarity, I know there is something missing...
