Hi, i am new (some months of use) to Sonar Artist Edition.

I am interested on getting a good and clean piano virtual instrument or soft synth. I have used the one that comes with Cakewalk TTS (Piano1, 2 and 3), but i am trying to find one a bit better. I know there is True Pianos for $199 but also don't want to spend so much money. I just need a good piano sound, at least 1.

Dimension PRO might have a few good ones, but there is no demo to see how they sound. Also at the Cakewalk Store i see the Stainway Grand Piano (Does this work with Sonar)? Is this only one instrument?


 
How many piano sounds are on Dimension PRO?

Thanks

Have you explored Rapture Session? It comes with Sonar Artist.

Yes, there are a few piano sounds, but not fully satisfied with the piano sound that i am looking :)

XLN Audio Addictive Keys might be worth checking out.
 
Edited to add:
 
Addictive Keys has a demo for Studio Grand that has some limitations but might be useful depending on your needs:
 
From the web site:
NO TIME LIMIT - use it as long as you like
INCLUDES demo version of the acclaimed Studio Grand (4 octaves, 3 mic perspectives)
THE FULL VERSION of Studio Grand offers all 88 keys and 6 mic perspectives - or buy any of the other AK instruments or bundles

Kontakt Player is free, and Native Instruments has a good reputation.

There are a lot of piano emulations out there -- from free to expensive. I've you could give us a better idea of what you're looking for specifically (grand, upright, etc.), and what your budget range is, you'll likely get better recommendations.

google/bing free piano VSTiand you will find a number of free pianos.  Maybe one or more of these will be what you are looking for in a piano sound.

These sound good!

True Pianos is pretty decent.  Comes with Plat.  Sample Tank has some good pianos too.

I use XLN Addictive Keys (Studio Grand, Mark One and Electric Grand), also True Pianos, and Dimension Pro has great Piano sounds too.

XLN Addictive Keys are sweet indeed, both Grand and Upright.
If you have Focusrite or Novation hardware, you'll get one for free.
Sonivox EightyEight is quite worthwile even at its low price under $20, and has some great layering capabilities.
Moving up in price, yet still under $50, have a look at the ones by Sampletekk, definitely if the 60% off sale is on.
Next, under $100, check out ImpactSoundworks Pearl Grand, SoundIron Emotional Piano and CineSamples Piano-In-Blue.
A little bit more will get you that sweet Mercury Grand by Wavesfactory or the Rosewood Grand by OrangeTreeSamples.
Then also look into the Native Instruments pianos, preferably as part of their Komplete bundle.
VI Labs TrueKeys are wonderful too, but you just missed the $199 sale.
And then there's the Bechstein Digital Grand, but you'll pay $249 for its glory.
