Arpeggiator
Hold a chord, hear an arpeggio. A Keyboard (or MIDI In) feeds an ARPEGGIATOR that plays the held notes back as a rhythmic line through a synth voice; a Clock drives the timing. Press play, then hold a chord on the keyboard. Shape it on the Arp: MODE (up / down / up-down / random / as-played / chord), OCTAVES, RATE, GATE — turn LATCH on to keep it going hands-free. A FUNCTIONAL preset (explicit nodes + connections).
