I’ve watched a video about the step sequencer and I’ve noticed that when I’m trying to select a colour for the first or the last sound on my step sequencer (colour selected -> gradient) it automatically selects all of the sounds in there. It does work normally if I’m selecting somewhere in the middle or even if I’m choosing ,for example, the first, third and fifth.
Simply just RIGHT-CLICK beside a sound on the Channel rack to highlight a sound. You can select and de-select sounds this way.
Then you can open the Gradient Editor by using the Keyboard Shortcut (SHIFT + ALT + C) .. or as you mentioned in the top-left arrow menu in the Channel rack (Step Sequencer) with “Color selected -> Gradient…”
If you’re still having issues with the Gradient not coloring properly, just reply back.. let me know if this helps okay?
