Hi,

I own a Roland HP 704 digital piano, but I suppose that the issue is the same one for all Roland digital pianos using Supernatural modelling to generate sounds, perhaps also Pure acoustic modelling.

Some notes sound brighter than others when played loudly. The best example is A4 of the Ballad Piano sound (the character of all notes is set to +1). Playing softly F4-G4-A4-B4-C4 endlessly, all notes sound equally balanced. Then playing louder the same sequence, the A4 sounds brigther than the others, and sounds "in front of the others".

It's possible to fix the issue with the Roland application Piano Designer, by lowering the character setting of A4 to 0. But the result isn't completely perfect, still unbalanced but in the reverse way : after lowering the character setting of A4, this note sounds then a little bit darker than G4.

Is anyone notice the same thing ? Does anyone modify the setup of some piano sounds to balance the character of all notes ?

Thanks for your feedback.

I've had exactly the same problem with my fp90. Adjusting with piano designer mitigates the problem to a degree but produces a duller sound. I've found the adjustment options to be non-intuitive, so it's possible someone else could get a better result but I doubt it. Most of the unnaturally bright (to the point of harsh and brittle) notes are in the upper octaves.

It's a long time since I did any adjustments to my LX706 but what I found is that where you have these differences it is a matter of balancing the character, volume and maybe even the tuning. In the case of the LX706, and I think the 708, it came tuned to 442 rather than 440 so adjusting that reduced the brightness and was especially noticeable with the higher octaves.

I’ll give a couple of thoughts here.

In the piano designer you can adjust the per note tuning and the default stretch tuning curve has some randomness to it. But a4 should be 0 I believe and so it is possible you have a bit of flatness to the surrounding keys.

Also, I believe the sympathetic resonance for the undamped upper register keys kicks in at g# so you might be hearing that on the A

Also, there may be some randomness in the key volume.

All of there these things can be adjusted with the piano designer app or with the piano designer option in the menu.

I changed the soundboard type, lid position and set resonances to mid-levels - this seamed to mitigate the issue of bright upper registers for me on my FP-90.

Have you tried if you get the same effect using quality headphones? I've noticed the "Roland" sound depends quite heavily on speakers/headphones used.

I'm glad to see that I'm not the only one to hear this unbalanced brightness. I posted the same question in French forums without success. I was asking myself if it wasn't my ears !

I tried to change a lot of settings, almost all, except tuning. I prefer soundboard 1 by far, as well as the lid setting to 6. Changing the volume does not improve anything and the problem is also present when listening through headphones. I also enjoy having several different Piano sounds, depending on the mood of the song.

I tried a few (but not all) tuning examples in the Piano Designer app, but I was not convinced. Has anyone found one that suits him ?

There remains the tuning ... It seems difficult to get into such settings. I am not a tuner. Yet it is true that the default tuning seems a bit irregular. It is undoubtedly perfectible. I found a Steinway tuning curve on the web. It is quite different. I'll try to apply it to see...

You should get the Roland piano designer app. It is quite easy to adjust the stretch tuning on that and save it to a library preset and save to the keyboard.

Once I found a piano sound I liked, I tweaked it a bit to suite my taste and fit better with my playback system such as equalization. Then, over time, I began to hear certain notes "jumping out" at me. It became very annoying! I found there are a few settings in the designer(?) controls where I could neutralize these differences and make that note have the same characteristics as the others.

The big question is why? Roland had to know these notes where deviant especially since they gave us the capability to make them like the others. I suspect Roland wanted to give the piano sound a character like real pianos. I never played a real piano that was perfectly tuned or adjusted. But.... over time... becoming very familiar with the particular RD2000 piano sound, these deviant notes started jumping out at me and ... well kinda got me mad.

The good is you can save your tweaks so when you power up, the piano is just the way you like it.

BTW, after I finally got the RD2000 to play like I wanted, I purchased my first VST, the Ravenscroft and, well, that is all I play now. To my ear and experience, this VST is just a better piano. Along with the keybed, (and great playback components) I now have a great system. I do like the feel of the RD2000 keybed.

Peace
