Loop Mode is crazy fun. It's like if a Loop Pedal and Midi Sequencer had a baby.... and named it Noise Machine.
Make sure the Midi CC Knob is set at zero. Play whatever notes you want, in whatever octave, in whatever order. Turn the Midi CC Knob... And BOOM, Noise Machine will play back those same notes in that same order, using the Midi CC Knob to control the BPM. As if that alone wasn't cool enough, you can control any modulation while the loop is playing by using the Octave Slider turned Midi Expression Slider. This mode works great in live settings, allowing up to 16 notes and/or pauses (Maybe more in future updates?).
Piano, Arps, Harps, Drums, Synths, Pads, you name it. Noise Machine's loop mode will have your creativity sparked, and you jamming in no time at all.
