I listened to the demos and it sounds great; they finally fixed the hollow bass notes problem with this piano in my opinion.
One of the main advantages of Pianoteq is the lack of noise build up. Even the best piano sample libraries suffer from noise build up. This is one of the inherent flaws of all sample libraries. No matter how good the microphones and converters, you will always get noise build up when playing complex pieces.
It is inevitable that Pianoteq (or any other modelling software- Arturia Piano V) will eventually catch up with the best sample libraries, like VSL, Ivory, Kontakt etc.
Sample libraries have probably peaked around the time VSL Steinway and Garritan CFX were released. The VSL Steinway was released in 2018 - 6 years ago.
Notice there haven't been many advancements in sampling technology since that time. There are only so many microphones and velocity layers you can add before you hit a plateau.
However things that can be improved in Pianoteq:
- Needs to take advantage of modern CPU/GPUs and offer higher resolutions within its synthesis engine.
- Needs a better reverb. The current reverb is grainy and metallic sounding. If you turn off the reverb in Pianoteq and use an expensive reverb like Valhalla or ChromaVerb set to ultra quality, the pianos can sound amazing. Especially if you run your sound interface at 96khz to get rid of the aliasing.
- UI can be improved - the graphics look kind of outdated and cheap. Especially those studio settings - why is there a green guitar in the studio next to the piano!
It is exciting times ahead for piano enthusiasts - I'm looking forward to Pianoteq 9 now and also Arturia's Piano V - which is due an update at the end of this year. That German piano model in Arturia's Piano V was something special and hopefully they can raise the bar further in the next update.
