The slide option is meant to blend the notes into each other as they play, but this option only works with FL native instruments. Leaving the repeat set to 0 will simply loop the entire arp as is. Typically, the more notes you have in the chord, the higher you’ll want to set the repeat to. The repeat option controls the point at which the arp will start over. You’ll likely want to stick to 1 to 3 octaves, but explore the full range to see how far you want to go. The range dictates the number of octaves the notes will arp into. Moving the knob to the left will shorten your notes, which can be useful in creating more of a plucking sound that might be useful for stringed instruments, like guitars. The second knob controls the note lengths.

Remember to either play this with your metronome or a drum pattern, so that you can match this up with your project tempo. It moves faster to the left and slower to the right. The first knob labeled time will adjust how fast the notes play. To arp the notes randomly, select the “?” option. The direction of the arrows will tell you which direction the notes will arp as it plays one at a time. Select any of the options to the right of the X to arpeggiate the notes in your chords. In the image above, you’ll see how it looks with it turned off. This is located under the wrench tool in each channel.

The most common option is through the channel settings. You can use the stock arpeggiator, which is built into the channel settings in each channel, the piano roll arpeggiator, which is accessed through alt+A, or use Riff Machine, which also has an arp section, built into it. In FL Studio, there are 3 ways to create arps from your chords.
