As for whether the P515 is triple sensor, they won't say. I've asked them to get back with me on that - but to my fingers, it doesn't seem to quite as fast of a response, or let me trigger notes without raising the key a bit.Just strike a note (without sustain pedal), and see if you can lift and restrike/retrigger the note without lifting the key so high that the previously struck note goes silent first. If you can do that, it has 3 sensors.

If you can't, it doesn't (or if it does, it ain't working!).Another way might be to use pianoteq's velocity curve wizard. It tells you whether your keyboard action is triple sensor or dual sensor.It would be quite embarrassing if Yamaha's mid to high end action (NWX), was only dual sensor.Pretty sure NWX is triple sensor. Perhaps the cp88 has a better triple sensor implementation?

Jun 9, 2017 - Are Graded Hammer Standard keys of the Piano are infereior than the Graded. I think natural terminology matches with GHS of Yamaha's.

Just in case some newbies on the forum saw that and got excited. The memory in these is not user accessible, but will be used by Yamaha to install periodic updates which will come in the form of OS updates, mainly including new sounds.That's too bad.

I would love to be able to delete unwanted voices and install what I want.I'm a little surprised that there are only 57 voices. Yamaha is falling far behind the latest competition on that spec.

Maybe the quality of the samples will somewhat makeup for the lack of voices. I'm shaking my head looking at the instrument sounds that are absent.Re: YAMAHA CP8801/16/19 03:52 PM 01/16/19 03:52 PMJoined: Oct 2017Posts: 1,181.

It would be quite embarrassing if Yamaha's mid to high end action (NWX), was only dual sensor.Pretty sure NWX is triple sensor. Perhaps the cp88 has a better triple sensor implementation?Read this:Yamaha only emphasizes the third sensor on the NW-GH and on the GH3, but not on the other actions, including the NWX. There is also no reference to the number of sensors on Yamaha's web pages that describe GrandTouch action used in CLP-685/75. Does the GrandTouch use three sensors? As anyone that has opened these DPs confirmed the actual number of sensors?Re: YAMAHA CP8801/16/19 03:55 PM 01/16/19 03:55 PMJoined: Nov 2018Posts: 51. NWX has three sensors.

I'm shaking my head looking at the instrument sounds that are absent.I was too at first, but then I thought it kind of makes sense. Yamaha is putting this out there as a 'stage piano' intended to be just that. 'CP73 and CP88 stage pianos feature a wide range of grand piano, upright piano, electric piano and keyboard sounds.'

If If you need more look at the Montage. Maybe same with Korg SV1 and Korg Kronos. I think we have come accustomed to tons of voices loaded into these stage pianos that blur the line of being a workstation ( ie.

All else being equal, more instruments is more attractive, and may spare a musician from having to buy another keyboard or from having to wire up a computer.Re: YAMAHA CP8801/16/19 04:44 PM 01/16/19 04:44 PMJoined: Oct 2017Posts: 1,181. NWX has three sensors. NWX has three sensors. The CP73 has balanced (equal across all keys) hammer action, and is using the same action in the Montage 8, minus the aftertouch.Where did you get this? Yamaha calls this CP73 action BHS (Balanced Hammer Standard) which doesn’t seem to live up to the Montage’s BHE (Balanced Hammer Effect) quality.Actually, the CP73’s BHS sounds like it’s in the same basic league as their often plagued and clunky GHS (Graded Hammer Standard).John, I sincerely hope you’re right about the CP73 having a Montage quality action, but BHS sounds like, well, standard.Re: YAMAHA CP8801/16/19 09:23 PM 01/16/19 09:23 PMJoined: Sep 2009Posts: 355.
