在录制这套4CD的巨型钢琴音色时,PMI公司使用了它们所能找的最好的钢琴。就是这台型号为D3，序列号为393210的大钢琴，出厂日期为1965年。在1999年被Steinway Hamburg重新复原。这台钢琴在荷兰鹿特丹的DOELEN音乐厅已经演奏了数十年，上百位最优秀的钢琴家弹奏过它。

When making the Grandioso Steinway D, they recorded the best grand piano they could find. This particular instrument was in premium condition, a Steinway model D3 with serial number 393210 which was built in 1965. It was fully refurbished by Steinway Hamburg in 1999. This piano served the Rotterdam 'DOELEN' concert hall for several decades, where hundreds of famous musicians, from Claudio Arrau to the Rolling Stones, performed for live audiences and broadcast concerts. Up to 6 articulations were captured (PPP, PP, P, MF, F, FF and FFF) for sustain pedal up, sustain pedal down and 4 articulations for the release triggered samples. They recorded the samples using the finest digital equipment available. Prism Sound, a 24-bit ProTools TDM Mix+ system and Waves processing was used. They mapped up to 16 levels of velocity, true multiple velocity release layers, ultimate staccato, and sustained pedal-down samples with a carefully chosen amount of resonance. The library has 5 GB of samples. The end result was tested by several concert pianists, who helped develop a sampled instrument which could meet their highest expectations. There is no doubt in our minds that this is the best sampled piano ever.
