Harpeggiator 1.3 (Gumroad)

An arpeggiator with a twist, this Max for Live device lets you create arpeggios by sweeping across held notes in every octave, like a glissando on a harp, hence the name. You can sweep manually with a fader or knob, automate it, or use an LFO or side-chain signal to dynamically control the arpeggiator. Also functions well as a MIDI guitar strummer.
