Hello, I share the same opinon as Lucy and Stephen. You will not have a real difference between 48000 and 192000 kHz. In comparaison, I saw for the great deal of people, the latency is a very important thing, and as the same, under 5 or even 10 ms, I never noticed a significant difference. It is also the same with the Midi dialect, standart or high resolution. I never listened a real difference. It is always better to try to have the best latency, sample rate and Midi dialect. Other thing that I do not understand, the latency seems to decrease when the sample rate increase.
With Realtek HD audio, I read in the options/devices of the Pianoteq that when the audio sample increase, for the same audio buffer size, the latency decrease.
Example : for 512 samples, at 44.000 kHz, 11.6 ms, at 48.000, 10.7 ms; ... ; 96.000 , 5.3 ms ; ... ; 192.000 , 2.7 ms
If someone could explain why, it would be nice.
I will go to a auditorium to try my Pianoteq 6 with a high end DAC first at 192.000 kHz and after at 48.000 kHz using a stereophonic class A amplifier. I will only take my laptop and use some Midi files than I record at home with Pianoteq 6 to do the test. If someone is interesting, I will write my own feeling of this experience.
With Pianoteq 6, at 192.000 kHz, the CPU usage stays under 25 per cent when playing for example the prelude in C sharp minor Opus 3 number 2 composed by Mr Rachmaninov, it is half of what Pianoteq 5 used.
