Well, what can I say, tubes afford huge dynamic range and so they go as
linear as

Dear Mihail

I am relatively sure that my native lanugage is the same as yours :)
and what you wrote in English is perfectly readible to me :)

Dear Josh Green
Thank you very much for your thorough explanations.
I did put "-o audio.alsa.device=hw:0" option to make fluidsynth
consume 10% instead of 100% of CPU.
Thanks again

Hello everybody,
I have read in the list archives that if there is noise while switching
windows, than the buffers and the number of them needs to be increased.
this will, however, will increase the delay in responce.
On my system I had to do fluidsynth -c 16 -z 1024 to get rid of the
noise. The q
