Hi there,
My P515 arrived 2 days ago and i'm enjoying it, but i am considering returning it as i'm struggling to get the bass notes that i want to.

I'm trying to get a clearer bass sound and the sound when you slap the keyboard (sorry only way i know how to explain it), i'm finding that i have to hit the keyboard far too hard to get the desired sound.

I'm not a proffessional pianist and don't know a whole lot about sound engineering.

Any help wouild be greatly appretiated.

You can't get a an electric bass guitar base out of a piano.

There is no key slapping.

But seriously ... I wonder whether the lack of bass strength in the P515 is just another example of inadequate speakers.
Good bass requires relatively heavy speakers situated in a proper enclosure.
Slab pianos are made to be relatively light and they don't have a proper enclosure.

That's just a fact of life with digital pianos. And that's why so many of us rely on separate sound systems.

I'm using headphones so that shouldn't really matter, Maybe im just not used to acoustic pianos or realistic actions, but i find my hands are red raw trying to a clear bass sound from the yamaha CFX sample

This could be your issue...
You may need an headphone amp.

There were some discussions about headphones in the past.
This could be helpful for you: http://forum.pianoworld.com/ubbthre...dt770-pro-32-80-250-ohm.html#Post3122039

The more ohm your headphones have, the better amp you need. But digital pianos usually don't have great amps.

Well, my hands would be red raw too after a session of slapping the keys of any piano. Fortissimo, especially in the bass of a graded weight action, would be achieved with arm weight, not hand slaps. But it is true that the P-515 has a heavy action and takes more force to play than most other slab digital pianos. If improper technique is used, it is an injury waiting to happen.

I am used to a much lighter plastic action on my YDP-141,
You are probably right that its to do with my technique as i have learned mostly on my old digital piano, however i find that even when i'm playing hard and not slapping the keys i can't get the sound that i want.

The 515 is certinly a different sound to your YDP, and a different action too.
If anything, I found the bass too heavy. There is plenty of room for scope with changing the response and tonal qualities, so give it at least a bit longer until you strike that happy place.
I got that with "Warm Grand" and "Studio Grand" which required more work on it.
Though folk including yourself might find the action heavy, I find it acceotable. i used to play a DGX which was lighter at the ends of the keys and sounded very nice.

I might suggest setting the touch to soft2 and turning up the volume.

I would also try adjusting the lid and brilliance.

You could also boost the low frequencies in the equalizer settings.

Good luck!

That's just a fact of life with digital pianos. And that's why so many of us rely on separate sound systems.

That's my first thought. If "inadequate speakers" is the cause, you could try experimenting with a sub-woofer, driven from the Left-side "Aux Out" (or "Line Out") jack.

Or getting a pair of powered monitors -- probably more expensive.

My second thought (free to test and implement)(and this applies to both loudspeakers and headphones):

. . . What is your volume setting, on the P-515 ?

(a) If it's less than 3/4, raise it to between 3/4 and full volume (or the highest level that doesn't distort), and see if the situation improves.

(b) If you play consistently at low volume, because of the Fletcher-Munson curve (see Wikipedia), you need to boost the bass, to get a balanced sound.

You can do that with the P-515 EQ (frequency equalization) settings, which are decently explained in the manual.

As a wise man said:

. . . You can't move two cows through a one-cow gate.

The little speakers in the P-515 can do their best, but it may not be good enough. If you want to sound something like an acoustic piano, in the bass, you need to move a lot of air. You'll need more power, and larger speaker cones, to do that.

EDIT -- DT770's have a good reputation. Raising the volume, and playing with EQ, should be enough to get decent bass.

Can you provide an example of "slapping" the bass keys, please?

Either your own video, or something uploaded by another pianist.

Kind regards,
James

Which bass notes, specifically, have you been struggling to get that you want .... which ones have you been slapping? Is it possible you want to hear more bass than what is intended, especially with headphones?

The DT770 Pro headphones are available in 3 variants: 250 Ohm, 80 Ohm and 32 Ohm. Which ones do you have?

If you got the 770s generally recommended for monitoring the play of a dp, they should provide neutral sound - bass, mid-range and treble - in other words, they are not intended to add or accentuate loudness of sound - like extra boomy bass - that is not there in the dp to begin with. If you got the 250 Ohm model, i suspect you might hear under-driven “weak” sound across the range of lows, mids and highs.

Also, you have numerous built-in classic songs as well as demo songs, both which demonstrate the sounds your dp is capable of producing, the former features piano sounds, the latter showcases the various voices “instruments” your dp is capable of playing. Both probably contain passages featuring bass notes. If you listen to some of them with headphone, this should confirm A) that you hear the intended level of bass that B) is or isn’t as much as you want.

If you are referring to a more exaggerated fortissimo “twang” when you strike the keys at a higher velocity, the fp90x would probably be a better fit. You can try to set a lighter touch sensitivity on your p515, bump up the brilliance, it should improve but you can’t change the samples overall. Alternatively if you like the action on the p515 you can look at VSTs such as Pianoteq steingraeber or NY Steinway.
