I figured out, that, to receive MIDI clock signal from the DAW, in Cubase, i have to go into the Transport menu, choose "Project sync options", or however it is called in English, and there, have to set up the Impulse's MIDI port, as the MIDI clock target, and, after 10 minutes of banging my head why it doesn't work
Ok, so, i thought i'd also try in Studio One. Thing is, though, when you set up your MIDI device, in my case, i set it up as a generic "New keyboard", because it isn't supported by Studio One out of the box, and the New keyboard devices don't offer the ability to receive, or send MIDI clock signals. So, my question is, is it possible, and issue free, when i add a "New instrument", transmitting, and receiving on the same MIDI port, to get MIDI clock signals working on my Impulse? It's really bad that you can't just add a "universal" device in Studio One, which can be keyboard, MIDI control device, with sliders, knobs, and what not, and at the same time a device which can transmit, and receive data, like MIDI clock signals.
