Pianoteq vs Stylus RMX

Pianoteq is a virtual piano and instrument suite that generates sound through physical modelling rather than built-in samples. It creates notes in real time, and the maker describes it as about 50 MB. More than 20 instrument packs cover electric pianos, plucked strings and historical keyboards. The software models sympathetic resonances and exposes physical parameters for adjusting tone. Pianoteq 9 can position and mix up to eight microphones to stereo or multichannel output. Desktop editions run standalone or in VST3, Audio Units and AAX hosts; NKS compatibility is also listed. It is available on iOS, Linux, macOS and Windows. There is no free plan, but the Pianoteq 9.2.5 evaluation version is full-featured with eight silent notes and a restart required every 20 minutes. Stage costs $139, paid once and includes two instrument packs; Standard costs $269, paid once with three packs, while PRO costs $399, paid once with four. The Studio Bundle is $929, paid once and includes PRO plus all current instrument packs.
