@ddw_music, thanks for the advice.

Wow, thank you very much , David!
It works now.

Hey guys,

I've just making first steps with Pd while reading Andy Farnell's Designing Sound book and he provided the simple sequencer example, which I can't make to work without modifications. So his patch is on the right and my working variant is on the left. What can be wrong?

You can see it in action in the attached video as well: Farnell_PdSequencer.mp4

Thanks,
Vitalii
