Techniques such as down- and up-strokes, slides and bends, hammer-ons and pull-offs, palm muting, muffled strings, and arpeggios are triggered by special strumming keys. Strum Electric also ships with a MIDI loops library which provides rhythmic figures, strumming patterns, and chord progressions in various musical styles.
