Yes, unfortunately!This topic has been requested on many occasions. The native metronome can not be changed, nor does it allow volume control. You can create a phrase.Here is a small solution.
You can also create a tool that automatically inserts a phrase (with the desired metronome).I included something similar in my tool GT16-Colors(it’s a small portion of the whole tool).
However, yes, Renoise should have a better native metronome, to change the measure and the volume, at least (and change the sound for something more advanced).
Maybe you should put a suggestion on this topic in the ideas and suggestions forum.I’ve seen a few users complain about this.
