I always avoided the physical modeling instruments beacuse i felt that
- computational load is much higher
- sound quality is lower
So for that concert grand piano sound I started out with the ‘The Grandeur’ from Galaxy Instruments [ http://www.galaxy-instruments.com/the-grandeur.html ] wich resembles a sampled Steinway Concert Grand. (99€)
It provides an average to good quality grand piano sound. But it never really made me feel at home with it.
After searching for better quality sound, I decided on the ‘Digital Grand’ from C. Bechstein (249€). That was a huge step upwards. Not only in cost and sound quality but also in loading times and time load (never measured just felt that way.)
Recently, with the release of Pianoteq 6 (99€, 2 Instruments) there was some hype around their product. I decided to give it a chance and downloaded the trial product Pianoteq Stage including all optional instrumunts but restricting usage to 20 minutes, after which a relaod is required, just enough time to perform some tests.
In general I rate the sound quality of the grand pianos to be equal to the Digital Grand, slightly better in the low and high registers.
Now with the profiler included in build 3543 one can directly compare the load profile of the three (using Kontakt Player VST plugin for the sample based instruments)
- The Grandeur, Instrument: The Grandeur.nki
- Digital Grand, Instrument: Digital Grand Player 1.1.0.nki
- Pianoteq VST plugin, Instrument: Steinway D Classical
Here are the results (using out of the box ettings, no tweaking):
- Total Sample Size 7.16 GB
- Loaded Patches in Memory 0.18 GB
- Profiler Memory Working Set: 0.6GB
- Profiler Max. Time Load (max/avg): 10%/4%
- Profiler Max CPU Load: 0,9%
- Total Sample Size 14.34 GB
- Loaded Patches in Memory 0.83 GB
- Profiler Memory Working Set: 1.5GB
- Profiler Max. Time Load (max/avg): 31%/12%
- Profiler Max CPU Load: 1,8%
- No Samples
- Profiler Memory Working Set: 0.4 GB
- Profiler Max. Time Load (max/avg): 15%/9%
- Profiler Max CPU Load: 2,7%
I expected a much higher CPU load, but it is just 50% higher than the Digital Grand, while the time load is 50% down. Very impressed.
Looks like physical modeling of grand piano has made it into the top league.
There are some other differences, like in the usability, user interface etc. which i did not investigate into. There is also a Standard and Pro version for those into tweaking the physical models.
Are you using physically modeled instruments? What kind? What are your thoughts and experience?
