piano sounds dull, muffled

I have Mainstage running on our Macbook Pros. We want to use it in the 'normal' way, keyboards hooked up to play live. But all the pianos (Yamaha, S'way, B'dorfer) sound muffled, like there is a filter taking out the highs. This is how it was out of the box.
It's the same on all the computers, and doesn't seem to matter what keyboard is hooked up-- now we have two new Kurzweil SP2X's USB'd.
I have searched! In the EXS24 window, there is filtering possible, and it was originally on, but now it's off. The EQ for the channel is off. no FX, just a bit of reverb.
Velocity is on, and that of course has an effect, but even at hardest playing still it sounds dull.

Is this your experience too? any ideas for a solution? absolutely any (intended relevant) suggestions gladly heard.
thanks in advance....

If you mean the Software Instrument EXS24 samples for piano sounds are lacklustre, I agree with you. I suspect poor choices when putting the samples together. I get around this by inserting Channel EQ & brightening the sounds up; this makes a big difference.

Usually problems like this one are down to some user preference being wrong; however, for once, I think it really is a dodgy set of samples (other people have complained about the string samples, too).

Thanks Caramby.
It seems to me that the samples are good, at least usable, quality. It's more like there is some kind of automatic filtering on the piano sounds. Yes, if i add EQ and crank up the high end, and fiddle a bit more, it begins to sound ok. I just wondered why it's like that in the first place, so obviously, strangely dull, it's not usable as it is.

I've had this happen a couple times to me ... and it invariably was because of one of two things:

A) the output was turned waaaay down on my audio interface (in software) ... so I had to crank my amp way up ... and it just didn't sound right

B) stereo / mono problems. Either the piano was sending to a mono bus, or I had stereo summing turned on in my amp, either way ... it sounded muffled and non-right.

Can the same be said of other instruments? For instance, if you change the channel strip to say a bright pad or an organ, do those sound similarly stifled? Plug some headphones into your audio interface or computer ... does it still sound raunchy? Cabling and amps ... that's usually where I find problems.

best of luck.

thanks for the ideas guys, including suggestion for 3d-party samples. i could try that to see if they are also 'damped'.
But it's not any of these things. it's driving me nuts because, i got this software because i use it in another show. it works great there, good chance for a tryout, i liked it, so i got it. In that show, there are piano sounds, afaik exactly the same as what i have, and those pianos don't sound muffled.
???

are you using the exact same setup as for the other show? If you're not using the same audio interface, that could make a HUGE difference alone right there. Is the sound guy tweaking the EQ in your monitor at the other show, maybe?

One other thing to check is the 'expression' setting on the channel strip (looks like the pan knob), if that's turned down that might do it ... should be all the way up.

Caramby, Ahicox, Carsimm, thanks a lot for the ideas.
good question about 'exactly the same'. no, not exactly. different keyboards for one: we use kurzweil sp2x's, the big show uses roland, i dont know what. the big show uses a big multi midi interface, we used small boxes, now USB (with no difference in sound). the macs are different, the show uses iMacs, we use two different macbook pros, one two years old, one brand spankin new, top of the line.
But the Logic/Mainstage is the same, the samples are the same, the adjustments (eq, filters, expression, effects etc) are the same, i.e., none. it's certainly not monitoring, system eq, that sort of thing. it's really a difference in the sound of the piano sample itself, coming out of the computer. i can use earphones for example, and still there is this difference.
do you think that the keyboards, or interface keys/computer (usb, midi) can make a difference?
really i don't think it's anything after the computer, monitoring or system eq or so.
it's not compression either, i know that sound, it's much more a 'dullness' of the tone of the sample, as if filtered. but it's not filtered! -- that i can find anyway.
btw-- i am using the logic/garageband samples, and they all haver the same filtered sound, like the steinway/b-dorfer/yamaha ones, you know, you get a choice of club, hall, room, studio.

i have been fiddling with the samples. using eq, lots of high end, some mids adjustment, i can get a reasonable tone. so it's as if there is a sort of autofilter. but where???

jeez. it just can't be like this out of the box, it's so ugly. yet it must be something with our setup, because that other one is not like this.
i am going crazy, spent so much time trying to figure this one out.

thanks again all!

If I understand correctly, you're saying that all sounds coming from mainstage sound as if they are being run through a filter, even when you plug headphones directly into the computer?

Can the same be said if you load up the same channel strips in Logic?

If they sound fine in Logic, that means there's a configuration in MainStage, which needs to be fixed. If they still sound wrong in Logic, maybe you have a problem overall on your computer?

Forgive me if any of this is repetitive, but this is getting quite a long discussion now (which is great, of course, but a bit harder to follow).

Have a good look around in the Parameters Window of EXS24. I said above that the piano sounds you mention are lacklustre, but one of the reasons for this is that they seem to come with a small amount of modulation (& other stuff) applied. *Turn all of that OFF.*

We all know that if one channel of stereo is out of phase with the other, when you sum the two channels to Mono you will lose frequencies. I believe this may be what you are observing.

Furthermore, many of the presets apply other plug-ins in the Channel Strips. So check in the Mixer that apart from the actual EXS24 plug-in (which obviously you need) there are no other naughty plug-ins interfering with your sound in way you don't like.

Pretty sure that if you follow the above suggestions, you will fix this. Here's hoping, anyway!

hi and geez, effusive thanks for your time and trouble.

Ahicox, great suffestion, i will try that. I haven't opened logic, even. No need for it yet, we got the whole set initially just for mainstage. will let you know.

Caramby, in the EXS24 window, all the mod possibilities are indeed off, no filters, no mods. adding filtering driven by velocity can go a long way to making a 'normal' piano sound.
I hear the sounds in stereo. again, with earphones, or through the speakers, it's the same. it also doesn't sound like mono dullness either, really it's as if it were filtered. EQing can make the sound sound more or less 'normal', bright.

NO plugins in the channel, i set them routinely off, in fact i find it a bit annoying that there is always EQ and compression and stuff already there, i wish the sounds would start up dry.

.......

I go forward.
thanks again!
