Topic: Pianoteq 6.4 is only available in 32 bit for Linux.
I went to download and it shows WIN listed as 32/64 bit but Linux is 32 bit only. Performance on 64 bit system for 32 bit s/w is less than optimum. I am forced to shut down some applications (such as WiFi) or the cpu overloads even on playback of a "last played on keyboard" midi. I am using Kubuntu 16.04.4 64 bit, low latency, with KDE and plasma 5.9.
