The Summer Sale just inspired me to take the plunge. I've purchased PT8 Standard plus one extra piano instrument:
Steinway D
Petrof
Bosendorfer
Bechstein
Steinway D is a no-brainer because it replaces my previous sampled Ivory American Concert D. Petrof has been highly regarded in this forum, with a warm and woody sound to complement the Steinways.
The new Bosendorfer surprised me. I've not been a Bosendorfer fan, but digging into the demos, the sonic purity in this instrument is amazing. I'll do some sound design and have a lovely main piano.
The Bechstein simply sounds nice to me and complements the others well. My favorite aspect of the sound is the lack of phasing that comes with mic placement with sampled VIs. I may play with mid-side mic options for perfect collapse to mono.
I expected the Pianoteq "sound". While it's there, it is much better than some of the Modartt demos suggested. Plus, responsiveness and playability of the models more than offset these subtle artifacts.
I really appreciate how lightweight modelling is compared to sampling. Instant launch, ultra low latency and glitch free. On a M2 Max CPU I reach perhaps 10% CPU load in dense passages.
Overall, very satisfied with this investment so far.
