Reliably ? At a latency below 10 ms ?
Which synth ? I don't intend to mistrust you, but I remain
disbelieving for now. :-)

Linuxsampler is well written and reliable, but
when playing intensely, it xran too here.

Interesting, although uneligible for my laptop..

Being generic means (for the platform) to support a bunch of
specialised applications.
It doesn't bother much to buy additional hardware, in order to make
the system more generic, but not being able to make it
generic enough for being able to use it for a cerain specialised application.
We are used to extend the systems usability through additional peripherials
such as graphic-cards, audio-cards, printers....
That's what has made it a success.

These make me lose the generality.

It absolutely would, if it gave me the same reliability.

I'm not making it bad. I'm even searching for a way to
make it more valueable by making it more usable.

I don't think my system is so badly configured - how to measure ?
It's not the most recent hardware, I admit.
