Have you see yet this video I made?
No I haven't, thank you!
L&R seem swapped.
3:18 - When you play very softly it seems like it is playing at a low volume not possible to achieve on a real piano. This IMO is a consequence of the 61 dB dynamic range, which seems perhaps too wide to me, but I suppose not obnoxious.
4:00 - I think I can hear stretching on the low end.
4:11 - The guitar voice sounds kind of fake.
3:38 - The harpsichord sounds pretty good, with the realistic "return quill" sample when the key is lifted.
6:50 - The pipe organ sounds like a mix of full pipes and chapel organ voices. The upper notes are a bit strident. I think I hear notes decaying unnaturally when you lift the keys with the sustain pedal down, something Yamaha does on other models and I'm not sure why (it sounds weird to me).
Sorry to be so critical, not trying to rag on the P-105 or your excellent playing! Thanks again!
