By default notes are added with a velocity (loudness) value of 100. (The range is 1 - 127.) Within Pattern Editor bold press SELECT to enable adjustment of note parameters. The velocity of a note may now be changed with the BACK encoder. This adjusts the velocity that new notes will have. It also adjusts the velocity of the currently selected note in the pattern. Alternatively with a touchscreen, press on an existing note and drag vertically to adjust the velocity.
