It is just me that turned off RT. Actually it works - it was among the
steps to perform in order to make running at all. Now as things become

Seems enabled:
snd_hrtimer 12604 1
snd_timer 22917 4 snd_seq,snd_pcm,snd_hrtimer

It seems working now - I suppose it was RoseGarden that made the

Oh, thank You for the information. Will be doing more tuning when MIDI
keyboard arrives.
Thank You for Your help!
