dewster For 16 bit stereo, 44.1k sample rate, this gives:
16MB / 2 bytes/sample / 2 stereo samples / 44100 samples/sec = 95 seconds of sample time. /88 = 1.08 seconds per note. To get any kind of realism out of it requires a stretching factor of at least 3x (and indeed there are 29 stretch groups on the P105 : 88/29=3.03).

. Due to affordability I am considering the YD P-115 which seems to have the same stretch issue as the P105 as referenced. The idea of the stretching does bother me, but is stretching for 3 notes that noticeable? Hey, if I could afford a Kawai ES110 I would just go for one. I have not found any ES110's used for any price and if I did, I know it would be for significantly more than than the $399 price that I can very regularly find a P-115 used for. Perhaps the fact that the P-45 and P-115 so often come up for sale as players move up the upgrade ladder is saying somthing about them (although many in that range would be piano students that just lose interest). Obviously players are hanging onto there ES110's though, and this is saying somthing about their quality. But should I really be worrying about the stretching issue so much? I know I sure notice my eMedia student KB sounds off and several along this thread have said stretching is noticeable and that gives me pause. I do find it interesting though that out of ALL the reviews for the P105 and P115 I have read NONE of them thought to mention note stretching comparisons with other DP's.

. I have read this through and thoroughly enjoyed its contents. I have also referenced back to it several times in my research of a DP. Thank you for all who have contributed to it.

Using an eMeda 61 KB for dummies Yup, That's really what it's called. Can you blame for wanting to upgrade to an 88 key Digital Piano (ie. YDP115w). Yep, I've got the bug for digital sound and 88 keys. I am learning to play using PianoVideoLesson.com Year 1 Course, and am currently in Unit 3.

I wonder if he wonders of fulcrum location, key weight or what chipset? He bought it to play, and imho, he does pretty well.



WHERE are all his videos? All there are here, are tutorials. I've listened to loads of his stuff, and excellent it is too. . . .
