sorry for my English. I want to know how to automatically make a percussion note line with the same spacing ?
Or repeating a note with the same spacing ?
In order to copy the spacing, you will need to copy at least two notes. In the piano roll select two notes and press copy. The two notes will be copied with the same spacing between them, but will be placed immediately after the last of the two notes. You then move the pair of notes to where you want them.
So if you draw in a kick on 1 & 2, select them, press copy, you would need to drag the two new kicks to 3 & 4. I find it useful to draw in a measure's worth of notes, press Select All, then Copy to copy the whole measure. Move the new measure of notes to line up with measure 2. Press Select All again, which highlights 2 measures, press Copy and move the two new measures to line up with measure 3. Press Select All again, highlighting 4 measures, press Copy and move the 4 new measures to line up with measure 5. That's now an 8 bar loop. Keep going as needed.
k. thanks to you
