This is where you can recommend to readers an alternative - or gear that goes with - MODARTT Pianoteq 4 Stage Software Piano Instrument. What gear sounds similar, is less expensive, higher-end or boutique, etc.?
I bought this at whatever version a couple of years ago and was very impressed with the sound but to get the full package it is rather expensive and I have other even more realistic sampled piano libraries so never use this now. Good if you have limited hard drive space as it is modelled and you can buy individual instruments covering modern and antique keyboard instruments and not only pianos but harpsichords, vibes anything in the keyboard family.
