Hello, thanks for the answer. I didn't know that I can control directly the tempo of the clock with cc (I don't understand on which input I should plug the inlet), this is why I used a square lfo between cc and clock, a lfo is easy to modulate.
About the run inlet, it works like a regular clock, at every new cycle of the square LFO, it starts the clock and generates an impulsion (so basically, my clock is the rate of my square LFO).
I know this part of the patch seems weird but it's ok for me.
The problem I have is that I can't use a midi/in/cc object, when I connect the inlet from midi CC to pitch from the square lfo, it doesn't work. The only way to make it work is to use the "midi/in/cc any" and use the value output (but every CCs from every channel from the octatrack will chaque the value from the lfo, which is not good for me). How can I use properly the midi/in/cc object ? Should I use a kind of convertor to transform the midiCC output into a Value output ? Thank you, this is my beginning on the Axoloti, so I have some understanding issues.
