A stock linux is completely sufficient, but you have to configure your linux user to be in the audio group. There is a README file in the Linux package of Pianoteque which offer same valuable hints.

You should invest into a dedicted sound interface (USB based for your laptop), as the mainboard audio often is suboptimal.

I'm getting very low latency even on an ARM board using the stock linux kernel.

I'm using Linux Mint 17.3 (Ubuntu 16.04) and I have no problems with latency even with a regular kernel.

Make sure you choose either a direct ALSA hardware device (don't use PulseAudio).

If you need multiple programs using simultaneous audio, then use JACK instead. In this case, you configure the audio settings (sample rate/buffer/latency/etc) in JACK instead of Pianoteq.

Oh the latest version 6.3.1 doesn't require any compiling. Nice.
It seems to work ok.
Is there a way to objectively measure the latency on linux?

Ubuntu Studio? If not, try installing RT kernel, also there is a little txt file with instructions in the compressed file for linux.

I run Ubuntu 18.04 (ie Kubuntu 18.04 ie KDE) linux on a Dell XPS 15 (9570). I want to install pianoteq on it but read there's likely latency problems to deal with due to either linux and/or the Dell laptop. What do I need to do to setup Pianoteq so it will run satisfactorily with decently low latency? I've read somewhere about JACK and ALSA, but don't know what I need to do to get it working.
